Ashes to Ashes

Gene Hunt's Quattro in the car park of BBC Television Centre

A red 1983 Quattro is driven by DCI Gene Hunt (played by Philip Glenister) in the television drama Ashes to Ashes (aired on BBC1 from 2008 to 2010). Multiple models were used through the run of the series, although always nominally portraying the same car; for example, the vehicle used in series 1 and the Children in Need Top Gear crossover mini-episode lacked a sunroof which was present on the car(s) used in series 2 and 3.

In the run-up to the 2010 general election, a campaign poster by the incumbent Labour Party government portrayed Conservative Party and opposition leader David Cameron as Gene Hunt sitting on the bonnet of the iconic red Audi Quattro and urged voters not to allow Cameron to take Britain "back to the 1980s" by electing his party into government amid fears that it would lead to a repeat of the social unrest and unemployment that Margaret Thatcher's Conservative government of that era oversaw. The image was then adopted by the Conservatives, with the slogan "Fire up the Quattro, it's time for cha

Audi Quatro S1
The original Audi Quattro competition car debuted in 1980, first as a development car, and then on a formal basis in the 1980 Janner Rally in Austria. Largely based on the bodyshell of the road-going Quattro models (in contrast to the forthcoming Group B cars), the engine of the original competition version produced approximately 300 bhp (224 kW; 304 PS). In 1981, Michèle Mouton became the first female ever to win a world championship rally, piloting an Audi Quattro.Over the next three years, Audi would introduce the A1 and A2 evolutions of the Quattro in response to the new Group B rules, raising power from the turbocharged inline 5-cylinder engine to around 350 bhp (261 kW; 355 PS).

The Quattro A1 debuted at the 1983 season opener Monte Carlo Rally, and went on to win the Swedish Rally and the Rally Portugal in the hands of Hannu Mikkola. Driven by Stig Blomqvist, Mikkola and Walter Röhrl, the A2 evolution won a total of eight world rallies; three in 1983 and five in 1984.

Audi Quatro

The Audi Quattro shared many componeThe Audi Quattro is a road and rally car, produced by the German automobile manufacturer Audi, part of the Volkswagen Group. It was first shown at the 1980 Geneva Motor Show on 3 March.
The word quattro is derived from the Italian word for "four". The name has also been used by Audi to refer to the quattro four-wheel drive system, or any four-wheel drive version of an Audi model. To avoid confusion, the original Quattro model is also commonly referred to as the Ur-Quattro - the "Ur-" (German for "primordial" or "ancestral") is an augmentative prefix, in this case meaning "original", and is also applied to the first generation Audi S4 and Audi S6 models, as in "Ur-S4" and "Ur-S6".



The Audi Quattro was the first rally car to take advantage of the then-recently changed rules which allowed the use of four-wheel drive in competition racing. It won competition after competition for the next two years. To commemorate the success of the original vehicle, all subsequent Audis with their trademark quattro four wheel drive system were badged "quattro" with a lower case "q". The original car with the upper case "Q" in the Quattro nts and the core of its body style with the Audi Coupé, which was a member of the Audi 80 (B2) model range. It was internally designated Typ 85, a type number it shared with the Audi Coupé GT, Audi Coupé quattro and Audi 4000CS quattro. Its characteristic flared wheelarches were styled by Martin Smith. The Audi Quattro also had independent rear suspension and independent front suspension.




European market
Audi released the original Quattro to European customers in late 1980,[1] making it both the first car to feature Audi's quattro permanent four-wheel drive system (hence its name), and the first to mate four wheel drive with a turbocharged engine.[

The original engine was the 2,144 cc (131 cu in) (2.1 L), inline-5 cylinder 10 valve SOHC, with a turbocharger and intercooler. It produced 147 kW (200 PS; 197 bhp) and torque of 285 N·m (210 ft·lbf) at 3500 rpm; propelling the Quattro from 0-100 km/h (62 mph) in 7.1s, and reaching a top speed of over 220 km/h (137 mph).[1]

The engine was eventually modified to a 2,226 cc (136 cu in) (2.2 L) inline-5 10 valve, still producing147 kW (200 PS; 197 bhp), but with peak torque lower in the rev-range.[1] In 1989, it was then changed to a 2,226 cc (136 cu in) inline-5 20v (2.2 L 20v) DOHC setup producing 162 kW (220 PS; 217 bhp), now with a top speed of 230 km/h (143 mph).[1]

Audi Quattros are often referred to among owners and enthusiasts by their engine codes, to differentiate between the earlier and later versions: the earliest 2144 cc 10v being the "WR" engine, the 2226 cc 10v being the "MB" engine, and the later 20v being the "RR" engine. Hence, Quattro models may be referred to as either the WR Quattro, MB Quattro, and RR or "20v" Quattro, respectively.

Quattro car production was 11,452 vehicles over the period 1980–1991,[1][2] and through this 11 year production span, there were no major changes in the visual design of the vehicle. For the 1983 model year, the dash was switched from an analogue instrument cluster, to a green digital liquid crystal display (LCD) electronic instrument cluster. This was later changed in 1988 to an orange LCD electronic instrument cluster. The interior was redesigned in 1984, and featured a whole new dash layout, new steering wheel design, and new centre console design, the switches around the instrument panel were also redesigned at this time. In 1985 the dash changed slightly with harder foam and lost a diagonal stripe, the dash switches were varied slightly and the diff lock pull knob gave way to a two-position turning knob with volt and oil temp digital readouts.


1987 MB engined Audi quattroExternal styling received very little modification during its production run. Originally, the car had a flat fronted grille featuring four separate headlamp lenses, one for each of the low and high beam units. This was altered for the 1983 model year, and replaced with combined units featuring a single lens, but housing twin reflectors. This was changed again, for the 1985 model year, in what has become known as the 'facelift model' and included such alterations as a new sloping front grille, headlights, and trim and badging changes. The RR 20v Quattro also featured a new three spoke steering wheel design, leather covering for door arm rests, gloveboxes, centre console and door pockets. There was also a full length leather wrapped centre console running all the way to the rear seats. 20v was also the first Ur-Q to have "quattro" script interior with partial leather seats. The floor on the drivers side had a bulge due to dual catalytic exhaust setup. The different models may be distinguished by the emblems on their boot lids: the WR had a vinyl 'quattro' decal or a brushed aluminium effect plastic emblem, the MB had chrome plated 'audi', 'audi rings' and 'quattro' emblems, whilst the RR had only chrome plated 'audi rings'.

The rear suspension was altered early on with geometry changes and removal of the rear anti-roll bar to reduce a tendency for lift-off oversteer. For the 1984 facelift, the wheel size went from 6x15" with 205/60-15 tyres to 8x15" wheels with 215/50-15 tyres. At the same time the suspension was lowered 20mm with slightly stiffer springs for improved handling. For 1987, the Torsen centre differential was used for the first time, replacing the manual centre differential lock.

North American market


Sales of the Quattro in North America began with the 1983 model year, which were constructed concurrently, and were of the same design as, the European 1982 models (they did not include the minor cosmetic changes of the European 1983 model) and continued through 1986. Total sales in the USA were 664. Canadian market received cars that were identical to the US cars with exception of the speedometer, which was metric like the early Euro cars. Official sales figures for Canada were 99, which included 61 in 1983, 17 in 1984, 18 in 1985 and 3 in 1986. Although it's believed that there might have been up to 6 cars bought in 1986.




US/Canadian cars were also equipped with larger impact bumpers with built in shock absorbers, just like the rest of the 4000/Coupé models. None of the cars came with Anti-lock Braking System (ABS), however they were otherwise "loaded" with options, including air conditioning, and in 90% of the cars, leather upholstery. Most of the 1984 and 1985 Canadian models did not have sunroofs. The remainder of the electric, suspension and cosmetic updates took place at the same time as the European cars. Out of 99 cars imported to Canada 35 are still known to be on the road.




The initial 2.1L (2144cc, engine code "WX") engine for US/Canadian models included minor component and engine control unit (ECU) changes, including lowered turbocharger boost pressure, different camshaft, emission controls including catalytic converter, and lambda stoichiometric fuel control, which lowered power to 160 hp (119 kW; 162 PS). Otherwise, mechanical specifications were identical to the European spec cars. The WX engine was also used on Swiss and Japanese market cars. In fact Audi built 200 special edition cars in 1988 with WX engine and analogue instruments, the rest of the car was identical to the MB cars of that year.

Audi

Birth of the company and its name

The company traces its origins back to 1909 and August Horch. The first Audi automobile, the Audi Type A 10 / 22 hp Sport-Phaeton, was produced in 1910 in Zwickau.

In 1909, Horch was forced out of the company he had founded.[3] He then started a new company in Zwickau and continued using the Horch brand. His former partners sued him for trademark infringement and the German Supreme Court (Reichsgericht in Berlin)finally determined that the Horch brand belonged to his former company.

August Horch was barred from using his own family name in his new car business, so he called a meeting with his best business friends, Paul and Franz Fikentscher from Zwickau. At the apartment of Franz Fikentscher they discussed how to come up with a new name for the company. During this meeting Franz's son was quietly studying Latin in a corner of the room. Several times he looked like he was on the verge of saying something but would just swallow his words and continue working, until he finally blurted out, "Father – audiatur et altera pars... wouldn't it be a good idea to call it audi instead of horch?" "Horch!" in German means "Hark!" or "hear", which is "Audi" in Latin. The idea was enthusiastically accepted by everyone attending the meeting.

Audi started with a 2,612 cc (2.6 litre) four cylinder model[clarification needed] followed by a 3564 cc (3.6 L) model, as well as 4680 cc (4.7 L) and 5720 cc (5.7L) models. These cars were successful even in sporting events. The first six cylinder model,[clarification needed] 4655 cc (4.7 L) appeared in 1924.

August Horch left the Audi company in 1920 for a high position at the ministry of transport, but he was still involved with Audi as a member of the board of trustees. In September 1921, Audi became the first German car manufacturer to present a production car, the Audi Type K, with left-handed drive.[7] Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer.

In August 1928 Jørgen Rasmussen, the owner of DKW, acquired the majority of shares in Audiwerke AG.[8] In the same year, Rasmussen bought the remains of the US automobile manufacturer Rickenbacker, including the manufacturing equipment for eight cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, six cylinder and four cylinder (licensed from Peugeot) models were manufactured. Audi cars of that era were luxurious cars equipped with special bodywork.

In 1932, Audi merged with Horch, DKW and Wanderer, to form Auto Union. It was during this period that the company offered the Audi Front which was the first European car to combine a six cylinder engine with front-wheel drive, using a unit shared with Wanderer but turned through 180 degrees so that the drive shaft faced the front.

Before World War II, Auto Union used the four interlinked rings that make up the Audi badge today, representing these four brands. This badge was used, however, only on Auto Union racing cars in that period while the member companies used their own names and emblems. The technological development became more and more concentrated and some Audi models were propelled by Horch or Wanderer built engines.

Reflecting the economic pressures of the time, Auto Union concentrated increasingly on smaller cars through the 1930s, so that by 1938 the company's DKW brand accounted for 17.9% of the German car market while Audi held only 0.1%.
[edit] Post-World War II

Like most German manufacturing, at the onset of World War II the Auto Union plants were retooled for military production, and immediately [citation needed]were subjected to heavy bombing for the rest of the war, leaving them all severely damaged.

Overrun by the Soviet Army in 1945, on the orders of the Soviet Union military administration the factories were dismantled as part of war reparations.[9] Following this, the company’s entire assets were expropriated without compensation.[9] On 17 August 1948 Auto Union AG of Chemnitz was deleted from the commercial register.[9] These actions had the effect of liquidating Germany's Auto Union AG. The remains of the Audi plant of Zwickau became the VEB (for "People Owned Enterprise") Automobilwerk Zwickau, AWZ for short (which translates into English as Automobile Works Zwickau).[10]

The former Audi factory in Zwickau, restarted assembly of the pre-war-models in 1949. These DKW models were renamed to IFA F8 and IFA F9 and were similar to the West German versions. West and East German models were equipped with the traditional and renowned DKW two-stroke engines.
[edit] New Auto Union

A new West German headquartered Auto Union was launched in Ingolstadt, Bavaria with loans from the Bavarian state government and Marshall Plan aid.[11] The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines.[11] This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F 89 L at Ingolstadt. The Ingolstadt site was a large one, consisting of an extensive complex of formerly military buildings which was suitable for administration as well as vehicle warehousing and distribution, but at this stage there was at Ingolstadt no dedicated plant suitable for mass production of automobiles: for manufacturing the company's first post-war mass-market passenger car plant capacity in Düsseldorf was rented from Rheinmetall-Borsig. It was only ten years later, after the company had attracted a relatively cash rich investor that investment funds became available for constructing a major car plant at the Ingolstadt head office site.

In 1958 Daimler-Benz took an 87% holding in the Auto Union company, and this was increased to a 100% holding in 1959. However, small two-stroke cars were not the focus of the company's interests, and while the early 1960s saw major investment in new Mercedes models and in a state of the art factory for Auto Union's, the company's aging model range at this time did not benefit from the economic boom of the early 1960s to the same extent as competitor manufacturers such as Volkswagen and Opel. It appears that the decision to dispose of the Auto Union business was based on its lack of profitability.[12] Ironically, by the time they sold the business it also included a large new factory and near production-ready thoroughly modern four stroke engine, which would enable the Auto Union business, under a new owner and with the benefit of a rediscovered name, Audi, to become one of Germany's most successful auto-makers during the second half of the 1960s.

In 1964 Volkswagen Group acquired a 50% holding in the business, which included the new factory in Ingolstadt and the trademark rights of the Auto Union. 18 months later Volkswagen bought complete control of Ingolstadt, and by 1966 were using the spare capacity of the Ingolstadt plant to assemble an additional 60,000 Volkswagen Beetles per year.[13] Two-stroke engines became less popular during the 1960s as customers were more attracted to the smoother four-stroke engines. In September 1965, the DKW F102 got a four-stroke engine implanted and some front and rear styling changes. Volkswagen dumped the DKW brand because of its associations with two-stroke technology, and having classified the model internally as the F103, sold it simply as the "Audi." Later developments of the model were named for their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972.
Audi 80 assembly line in Wolfsburg as of 1973

In 1969, Auto Union merged with NSU, based in Neckarsulm, near Stuttgart. In the 1950s, NSU had been the world's largest manufacturer of motorcycles, but had moved on to produce small cars like the NSU Prinz, the TT and TTS versions of which are still popular as vintage race cars. NSU then focused on new rotary engines based on the ideas of Felix Wankel. In 1967, the new NSU Ro 80 was a space-age car, well ahead of its time in technical details such as aerodynamics, light weight, and safety but teething problems with the rotary engines put an end to the independence of NSU. Today the Neckarsulm plant is used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the quattro GmbH, this subsidiary is responsible for development and production of the Audi high performance cars: the R8 and the "RS" model range.

The mid-sized car that NSU had been working on, the K70, was intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80. However, Volkswagen took the K70 for its own range, spelling the end of NSU as a separate brand.
[edit] Modern era

The new merged company was known as Audi NSU Auto Union AG, and saw the emergence of Audi as a separate brand for the first time since the pre-war era. Volkswagen introduced the Audi brand to the United States for the 1970 model year.

The first new car of this regime was the Audi 100 of 1968. This was soon joined by the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design in many ways, because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car.
Audi Quattro

The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger[14] was accepted to develop the four-wheel drive technology in Volkswagen's Iltis military vehicle for an Audi performance car and rally racing car. The performance car, introduced in 1980, was named the "Audi Quattro", a turbocharged coupé which was also the first German large-scale production vehicle to feature permanent all-wheel drive through a centre differential. Commonly referred to as the "Ur-Quattro" (the "Ur-" prefix is a German augmentative used, in this case, to mean "original" and is also applied to the first generation of Audi's S4 and S6 sport sedans, as in "UrS4" and "UrS6"), few of these vehicles were produced (all hand-built by a single team), but the model was a great success in rallying. Prominent wins proved the viability of all-wheel drive racecars, and the Audi name became associated with advances in automotive technology.

Alfa Romeo 1900



The Alfa Romeo 1900 is a sports sedan designed by Orazio Satta for the Alfa Romeo company in 1950. It was Alfa Romeo's first car built entirely on a production line and was also Alfa's first production car without separate chassis and first Alfa offered with left-hand drive. The car was introduced first time for bigger audience in 1950 Paris Motor Show.



The 1900 was offered in two door or four door models, with a new 1884 cc, 90 bhp, 4 cylinder twin cam engine. It was spacious and simple, yet quick and sporty. The slogan Alfa used when selling it was "The family car that wins races", not-so-subtly alluding to the car's success in the Targa Florio, Stella Alpina, and other competitions. In 1951 the short wheelbase 1900C (c for corto (Italian for short) version was introduced. It had a wheelbase of 2,500 mm (98.4 in). In the same year the 1900TI with a more powerful 100 bhp (75 kW; 101 PS) engine was introduced, it had bigger valves, a higher compression ratio and it was equipped with a double carburetor. Two years later the 1900 Super and 1900 TI Super (also 1900 Super Sprint) with 1975 cc engine were introduced. The TI Super had two double carburetors and 115 bhp (86 kW; 117 PS). Transmission was a 4-speed manual on basic versions and 5-speed manual in Super Sprint version, the brakes were drum brakes. The 1900 has independent front suspension (double wishbones, coil springs and hydraulic telescopic shock absorbers) and live rear axle.

Production at the company's Milan plant continued until 1959: a total of 21,304 were built, including 17,390 of the saloons.

The chassis was designed specifically to allow coachbuilders to rebody it, the most notable of which was the Zagato designed, 1900 Super Sprint Coupe, with an improved engine and custom body design. 1900M AR51 or "Matta" is 4wd off-road variant of this car.


1900 SS Zagato

Alfa Romeo 6C


Alfa Romeo 6C name was used on road, race and sports cars made between 1925–1954 by Alfa Romeo. 6C refers to a straight 6 engine. Bodies for these cars were made by coachbuilders such as James Young, Zagato, Touring, Castagna, and Pininfarina. Starting from 1933 there was also a 6C version with a factory Alfa body, built in Portello. n the mid-1920s, Alfa's RL was considered too large and heavy, so a new development began. The 2-liter formula that had led to Alfa Romeo winning the World Championship in 1925, changed to 1.5 liter for the 1926 season. The 6C1500 was introduced in 1925 at Milan, production started 1927, with the P2 Grand Prix car as starting point. Engine capacity was now 1487 cc, against the P2's 1987 cc, while supercharging was dropped. First versions were bodied by Young and Touring.

In 1928, a 6C Sport was released, with a dual overhead camshafts engine. Its sport version won many races, including the 1928 Mille Miglia. Total production was 3000 (200 with DOHC engine). Ten copies of a supercharged (compressore, compressor) Super Sport variant were also made.

A.L.F.A 24 HP


The A.L.F.A 24 HP came on the market in 1910. This was the first automobile created by A.L.F.A (later Alfa Romeo). Giuseppe Merosi was the man behind engineering. The car was used for the first time in car racing in the 1911 Targa Florio. This was first commercial success for the company and the timeline of the HP series tells that the car was continuously developed onwards. The 24HP had a 4,082 cc (249.1 cu in) straight-4 sidevalve engine, which produced 42 bhp (31 kW) with 2200 rpm and gave top speed of over 100 kilometres per hour (62 mph). Until 1913 approximately 200 A.L.F.A 24 HPs were built.

The engine designation consisting of a number as well as "HP" came from the then usual designation of tax schedules. The 24HP became the starting point of a whole series of vehicles, which were built until 1921 and included:

* 12HP , 2413 cc straight-4 and 22 bhp (16 kW), (1910–1911)
* 15HP , 2413 cc straight-4 and 25 bhp (19 kW), (1912–1913)
* 40-60 HP , 6082 cc straight-4 and 70 bhp (52 kW), (1913–1914)
* 15-20 HP , 2413 cc straight-4 and 28 bhp (21 kW), (1914–1915)
* 20-30 HP , 4082 cc straight-4 and 49 bhp (37 kW), (1914–1920)
* 20-30 ES Sport , 4250 cc straight-4 and 67 bhp (50 kW), (1921

Alfa Romeo history


The company that became Alfa Romeo was founded as Società Anonima Italiana Darracq (SAID) in 1906 by the French automobile firm of Alexandre Darracq, with some Italian investors. One of them, Cavaliere Ugo Stella, an aristocrat from Milan, became chairman of the SAID in 1909. The firm's initial location was in Naples, but even before the construction of the planned factory had started, Darracq decided late in 1906 that Milan would be a more suitable location and accordingly a tract of land was acquired in the Milan suburb of Portello, where a new factory of 6,700 square metres (8,000 sq yd) was erected. Late 1909, the Italian Darracq cars were selling slowly and Stella, with the other Italian co-investors, founded a new company named A.L.F.A. (Anonima Lombarda Fabbrica Automobili), initially still in partnership with Darracq. The first non-Darracq car produced by company was the 1910 24 HP, designed by Giuseppe Merosi, hired in 1909 for designing new cars more suitable to the Italian market. Merosi would go on to design a series of new A.L.F.A. cars, with more powerful engines (40-60 HP). A.L.F.A. also ventured into motor racing, drivers Franchini and Ronzoni competing in the 1911 Targa Florio with two 24 HP models. In 1914, an advanced Grand Prix car was designed and built, the GP1914 which featured a four cylinder, double overhead camshafts, four valves per cylinder and twin ignition. However, the onset of World War I halted automobile production at A.L.F.A. for three years.

In August 1915 the company came under the direction of Neapolitan entrepreneur Nicola Romeo, who converted the factory to produce military hardware for the Italian and Allied war efforts. Munitions, aircraft engines and other components, compressors and generators based on the company's existing car engines were produced in a vastly enlarged factory during the war. When the war was over, Romeo invested his war profits in acquiring locomotive and railways carriage plants in Saronno (Costruzioni Meccaniche di Saronno), Rome (Officine Meccaniche di Roma) and Naples (Officine Ferroviarie Meridionali), which were added to his A.L.F.A. ownership. Car production had not been considered at first, but resumed in 1919 since parts for the completion of 105 cars were still lying at the A.L.F.A. factory since 1915.[5] In 1920, the name of the company was changed to Alfa Romeo with the Torpedo 20-30 HP becoming the first car to be badged as such.[7] Their first success came in 1920 when Giuseppe Campari won at Mugello and continued with second place in the Targa Florio driven by Enzo Ferrari. Giuseppe Merosi continued as head designer, and the company continued to produce solid road cars as well as successful race cars (including the 40-60 HP and the RL Targa Florio).

In 1923 Vittorio Jano was lured away from Fiat, partly thanks to the persuasion of a young Alfa racing driver named Enzo Ferrari, to replace Merosi as chief designer at Alfa Romeo. The first Alfa Romeo under Jano was the P2 Grand Prix car, which won Alfa Romeo the inaugural world championship for Grand Prix cars in 1925. For Alfa road cars Jano developed a series of small-to-medium-displacement 4, 6, and 8 cylinder inline power plants based on the P2 unit that established the classic architecture of Alfa engines, with light alloy construction, hemispherical combustion chambers, centrally-located plugs, two rows of overhead valves per cylinder bank and dual overhead cams. Jano's designs proved to be both reliable and powerful.

During the 1960s, Alfa concentrated on competition using production-based cars, including the GTA (standing for Gran Turismo Allegerita), an aluminium-bodied version of the Bertone-designed coupe with a powerful twin-plug engine. Among other victories, the GTA won the inaugural Sports Car Club of America's Trans-Am championship in 1966. In the 1970s, Alfa concentrated on prototype sports car racing with the Tipo 33, with early victories in 1971. Eventually the Tipo 33TT12 gained the World Championship for Makes for Alfa Romeo in 1975 and the Tipo 33SC12 won the World Championship for Sports Cars in 1977.

By the 1970s Alfa was again in financial trouble. The Italian government company Finmeccanica bowed out in 1986 as Fiat Group bought in, creating a new group, Alfa Lancia Industriale S.p.A., to manufacture Alfas and Lancias. Models produced subsequent to the 1990s combined Alfa's traditional virtues of avant-garde styling and sporting panache with the economic benefits of product rationalisation, and include a "GTA" version of the 147 hatchback, the Giugiaro-designed Brera, and a high-performance exotic called the 8C Competizione (named after one of Alfa's most successful prewar sports and racing cars, the 8C of the 1930s).

In 2005 Maserati was bought back from Ferrari and brought under Fiat's full control. The Fiat Group plans to create a sports and luxury division from Maserati and Alfa Romeo. There is a planned strategic relationship between these two; engines, platforms and possibly dealers will be shared in some market areas.

In the beginning of 2007, Fiat Auto S.p.A. was reorganized and four new automobile companies were created; Fiat Automobiles S.p.A., Alfa Romeo Automobiles S.p.A., Lancia Automobiles S.p.A. and Fiat Light Commercial Vehicles S.p.A. These companies are fully owned by Fiat Group Automobiles S.p.A.

Racin History
Alfa Romeo has always been involved with motor racing. In the 1920s and 30s Alfa Romeo scored wins at many of the most famous and prestigious races and motoring events such as Targa Florio, Mille Miglia and Le Mans. Great success continued with Formula One, Prototypes, Touring and Fast Touring. Private drivers also entered some rally competitions, with fine results. Alfa Romeo has competed both as a constructor and an engine supplier, via works entries Alfa Corse, Autodelta and private entries. Today Alfa Romeo is active in different Touring car series and the new Alfa Romeo 8C Competizione is planned to take part to Le Mans GT2 class in the near future

E24, maybe the most beautiful BMW



The BMW E24 series was the first BMW 6 Series coupé, produced by the German automaker BMW between the 1976 and 1989 model years. The 6 Series name reappeared with the BMW E63 chassis beginning in the 2004 model year. The E24 borrowed heavily from contemporary 5-series cars (E12, later E28). Model history

The E24 was a replacement for the CS and CSL coupés first produced in 1965. The CS 3.0 was almost changed by adding a few inches in height to make it easier for customers to get into the car. However, Bob Lutz rebelled against the decision and rough drafted an alternative version that soon became the 6 series[2]. Production started in March 1976 with two models: the 630CS and 633CSi. Originally the bodies were manufactured by Karmann, but production was later taken in-house to BMW.

In July 1978 a more powerful variant, the 635CSi, was introduced (for the time being not available in North America and Japan) that featured as standard a special close-ratio 5-speed gearbox and a black rear spoiler.

In 1979 the carburetted 630CS was replaced with the 628CSi; this car had a fuel injected 2.8L engine taken from the BMW 528i.

In 1982 (Europe) and 1983 (US), the E24 changed slightly, with an improved interior and slightly modified exterior. At the same time, the 635CSi received a new engine, a slightly smaller-bored and longer-stroked 3430 cc six to replace the former 3453 cc engine and became available with a wide-ratio 5-speed or an automatic.

E24s produced after June 1987 came with ellipsoid headlamps instead of the halogen lamps of earlier models. The sleeker European bumpers were also discontinued. Previous cars had either a European-standard bumper or a larger, reinforced bumper to meet the US standard requiring bumpers to withstand impact at 5 mph (8 km/h) without damage to safety-related components. 1989 was the last year for the E24 with production stopping in April. The E24 was supplanted by the considerably heavier, more complex, and more exclusive E31.
M Version

The M635CSi was introduced in Europe at the Frankfurt Motor Show in 1983. It is essentially an E24 powered by the powerplant of the BMW M1 (the M88, now putting out 286 PS (210 kW; 282 hp)). Most M635csi's were equipped with special metric 415 mm diameter wheels requiring Michelin TRX tires. A catalyzed, lower compression ratio version of the car with the S38 engine putting out 260 PS (190 kW; 260 hp) was introduced in the U.S. in 1987. All M635/M6s came standard with a 25% rear slip differential. U.S. models included additional comforts such as Nappa leather power seats and a dedicated rear A/C unit with a center beverage chiller. Car and Driver tested a U.S. M6 in July 1987 and achieved a 0-60 time of 6.1 seconds, better than the BMW published 6.4 and 6.8 second times for the European and U.S. versions respectively. 4,088 M635CSis were built between 1983 and 1988 with 1,767 U.S. M6s built.[3]
In mid-model year 1978 the 630CSi was replaced by the 633CSi. US/Japan specification 633CSi cars had the M30 3.2 litre 181 hp (135 kW) engine until 1984. In 1985 the car was renamed 635CSi, displacement was increased to 3.4 litres and horsepower increased slightly to 182 hp (136 kW). The big difference, however, was torque. Whereas the 3.2 litre had 195 ft·lbf (264 N·m) at 4,000 rpm, the 3.4 litre powerplant managed 214 ft·lbf (290 N·m) at 4,000 rpm.

From model year 1983, North American and Japanese versions benefitted from the technical revisions and changes to the interior introduced elsewhere in spring or summer 1982. Its chassis was now based on the E28 and no longer on the E12. The front and rear suspension was also revised. Later a self-levelling rear suspension was added to the 635 CSi and M6 features list in 1988.

The US received its own M series E24 in 1987 called the M6. The S38 powerplant found in the US model had several modifications from the M88 powerplant in the European model, most notably: a double row timing chain, modified cam tray, different valve lengths, a slightly different cam profile, less elaborate exhaust manifold (rather than full headers), Bosch X5DC copper spark plugs (instead of Bosch Silver plugs on the M88) and the introduction of an oxygen sensor for the EFI. These changes coupled with the introduction of a catalytic converter for emission regulations reduced the output to 256 hp (191 kW). The US model also included a variety of options not found on the earlier European models, to include: heated power seats, sport tuned self-levelling rear suspension, A/C cooled ice box between the rear seats, A/C vents for rear seat occupants, sunshade for rear occupants and an 8 speaker "premium" sound system.


E24 M6

In 1988, the US E24 was now available with the newest version of the M30, the 3.4L (first used in the E32 735i). Even though the intake manifold states 3.5 it's technically a 3.4 (3430cc) like the previous 3.4. This engine had an increased compression ratio, and updated Motronics/DME. The result was 208 hp (155 kW) and 225 ft·lbf (305 N·m) torque. In effect, this engine was identical to the catalyzed version newly available in Germany and other markets.

Volvo 900 series



The Volvo 940 is among the last in the long-running line of large rear-wheel drive cars from Volvo. Introduced in 1991, the 940 was essentially a cosmetic reskinning of the 740. All drivetrains, and most options available in the 940 had been available in the 740. The 940 was more closely related to the 740 than the 760, sharing the same dashboard, drivetrain choices, and sheet metal from the A-pillar forward. In contrast, the 960 was an evolution of the 760. The 760 / 960 front sheet metal, independent rear suspension, dashboard, and other interior features were all exclusive to the two upscale models.
1994-1995 Volvo 940 Turbo sedan (US)



In the United States, the 1991 940 was offered in three versions: the 940GLE used a DOHC 16-valve version of the 2.3-litre engine with a 6000 rpm redline. The 940 Turbo used a turbocharged 2.3-litre engine, and the top-end 940SE (turbo) included body-coloured trim, and the premium features (leather, power seats/moonroof, etc.) as standard equipment.

In 1992, the 940 GLE was downgraded with a 114 bhp 2.3-litre 4-cylinder engine and sold as the 940 GL (or basic 940 in some export markets). The 940 SE was altered in such a fashion that it was a 960 Turbo sold as the 940 SE, but the 940 Turbo remained largely unchanged. Production of the 940 series ended on February 5, 1998.

Autumn 1990 saw the launch of the Volvo 960 in time for the 1991 model year. This was the replacement for the 760. The 1991 960 was an evolutionary progression of the 1990 760, but it was also one of the first cars to feature the work of British designer Peter Horbury. The most significant change was that, in most markets, the 960 was offered with an all-new aluminum 24-valve DOHC inline six-cylinder engine, often referred to as "white block" in the Volvo community due to its bare aluminum block. Some markets, such as Australia, saw 1991 960s equipped with the same B280 V6 engine that had powered the 1990 760. The 1992 model year saw the U.S. introduction of the DOHC inline six-cylinder engine. For the Italian and Portuguese markets, the 960 was available with the 16v 2-litre turbo for the model year 1991-1994 along with the 2.5 and 3.0 inline 6 engine.
Volvo 960 wagon (US)


The 960 received incremental changes for the 1992, 1993, and 1994 model years. Most visible were the new more shapely seats, and redesigned seat-belts with hydraulic pretensioners for 1992. 1993 saw a new more ergonomic shifter, and in 1994 dual front airbags were introduced in some markets. The opaque sunroof was replaced by a sliding sunshade and glass window.

For 1995, the 960 underwent radical changes.[2] Most obvious was the more aerodynamic front end, and more body-coloured panels. Underneath, the front suspension was completely retooled to more closely match that of the 850. Indeed, 1995 to 1998 960s may use the same wheels as 1994 and newer front-wheel drive Volvo models. The rear suspension received a completely redesigned multi-link independent system. Instead of conventional coil springs, Volvo used a single transverse fibreglass leaf spring. The 1995 960 station wagon marked the first time ever that Volvo equipped one of its rear-wheel drive station wagons with an independent rear suspension. Boge's Nivomat self-levelling rear suspension system became an option rather than standard equipment.

Production of the 960 ended on February 5, 1998. Some 1997 and all 1998 model year vehicles were renamed the Volvo S90/Volvo V90 to match the letter-and-number naming scheme now used on their other models.

The 1992-94 Volvo 960s were built in Kalmar, Sweden. The very first Volvo 960 for the US-market rolled off the assembly line on August 12, 1991 as a 1992 model. The 1995 to 1998 960s were built in Göteborg, Sweden. The first 1995 960 was built on June 27, 1994.

All US cars were equipped with an electronically controlled Aisin AW-series automatic transmission. Beginning in the 1995 model year, European cars with the 2.5 L engines were also available with a manual transmission, the so-called M90, a strong new design that was derived from the Volvo 850's transmission. With the demise of the 2.5 L engine, the M90 was paired with a detuned version of the 3.0 L engine.

Volvo 700 series

The Volvo 700 and 900 series are two ranges of mid-size car manufactured by Volvo Cars in the 1980s and 1990s. The 700 series was introduced in 1982, followed in 1990 by the 900 series. The 700, designed by Jan Wilsgaard, was originally to have been a replacement for the 200 series, but production of that model continued.

The most visible differences between the 700 and the 900 series were the more rounded corners on the body of the latter, and a somewhat better-appointed interior. The 960 was substantially revised for the 1995 model year, improving the handling. The range was first augmented and finally supplanted by the Volvo 850 in 1993, with the last of the 900s being sold in 1998. Some 900 series were built as chassis for ambulances and hearses after the main production run had been completed. he 760 was Volvo's attempt to cement a place in the prestige market, after building a reputation for being solid and safe rather than out-and-out luxurious cars. Jan Wilsgaard, head of Volvo's Design and Styling team, proposed over 50 new designs for the new car. It was introduced to the US in 1982 for the 1983 model year as the 760 GLE sedan. This new design was criticized by the media when released: Gordon Murray of Autocar Magazine said, "To me it's obscene! That goes right against the grain of what everybody else is trying to do. To me it looks like a European version of a North American car. It produces the same amount of power as a 2600 or 3500 — in this day and age it disgusts me to see something about like that. It's a definite step backwards." All that changed however when Autocar and Car & Driver got their hands on a turbo intercooled 760; they said it was one of the best handling and fastest accelerating cars they had seen in a while, thundering from 0-60 mph (97 km/h) in under 8 seconds.[citation needed]
1984–1985 Volvo 760 Turbo sedan (Australia)

Turbocharged and intercooled variants were added in 1984, station wagon variants and the 740 – the 760's lower-specification sibling – were introduced for the 1985 model year. In 1985 Electronic Traction Control system was introduced. For the 1988 model year, the 760 received numerous updates. From the outside, the most noticeable of the over 2,000 changes were the revised front sheetmetal, including an aluminium hood, recessed windscreen wipers, and new aerodynamic headlights. Inside, all 760s were equipped with a new electronic climate control (ECC), a revised dashboard, three-position tilt steering, and a new stereo system. Underneath, sedans received the same multi-link independent rear suspension that was used on the 780.[1] Along with the revised dash, the interior saw the addition of a revised dome light and many fabric accent pieces.

The Volvo 760 was also used as a police car in several countries. East German leader Erich Honecker also often used this Volvo in his governmental car pool.

For its final year of production, 1990, 760 sedans received tail lights in the style of the Volvo 780 (see below), and minor interior changes. The 760 was discontinued after the 1990 model year (with production ending on 27 June 1990), and was replaced by the Volvo 960, an evolutionary update of the 760 chassis. The Volvo 740 outlived the 760, remaining for another two years.

All 760s were built in Kalmar, Sweden, or Ghent, Belgium.

During a challenge on the British television motoring series Top Gear, the team are given a challenge to purchase fully legal cars (with road tax and a valid M.O.T.) for less than £100, presenter Jeremy Clarkson purchased a Volvo 760 GLE, and won the overall challenge, mainly because his car cost only £1, and was the only car still working after a 30 mph (48 km/h) crash they had at the end.

Volvo 740


Introduced in the U.S. for the 1985 model year, the 740 was a more simply equipped version of the Volvo 760. The 740 was intended to be a mid-size car that offered more style, performance, and luxury than the venerable 200 series.
Volvo 740 wagon (US)

In the U.S., the 740 was offered from 1985 to 1992 as a 4-door sedan (known internally as the 744) and a 5-door station wagon (known internally as the 745). Production of the 740 ceased in 1992, though the engine, transmission, chassis, and other details lived on in the Volvo 940, which was essentially a re-skinned 740. Though out of production for over 15 years, the majority of these cars are still on the road today, thanks to robust construction and engines known to run for hundreds of thousands of miles.[citation needed]
Volvo 700-series sedan (US)

In 1990 the 740 received a minor facelift with new composite headlamps and 780-style tail lights. In 1991, both the 740 and the newly introduced 940 received an updated dashboard, similar in appearance to the ones found in the 760. The 740 remained mostly unchanged for the 1992 model year, and was phased out in 1993 in favour of the Volvo 940.

Aside from styling, 1990 marked a number of mechanical improvements to the 740 series. The B230 motor received larger 13 mm (0.5 in) connecting rods. The 740 Turbo switched from the Garrett T3-series turbocharger to the Mitsubishi TD04 series, offering quicker spool-up and better low-RPM boost at the expense of top-end performance. The fuel system was upgraded from Bosch LH-Jetronic 2.2 to 2.4 (in 1988 for naturally aspirated cars, 1990 for Turbo cars). The newer fuel system offered onboard diagnostics, which are easily accessible from under the hood, and require no special equipment. In 1992, the final year for the 740, the mechanical engine cooling fan was replaced with an electric fan. In short, many of the mechanical lackings of the 1985-89 740s were ironed out in the 1990-92 model years. The 1990-92 Volvo 700-series cars may very well represent one of the most reliable 4-door passenger sedans of its era due to a limited number of engineering limitations and solid build quality.

Trim levels were GL, GLE and GLT worldwide; Continental markets had some exceptions to this rule. The most interesting exception was perhaps the 740 Turbo 16v sold only in Italy. This car used the B204FT engine found also in the 780 on the same market and it came with some unusual extras such as the ECC from the 760.

The Volvo 780 grand touring coupé made its debut at the International Auto Show in Geneva, Switzerland in 1985. It marked the return of a two-door 2+2 seater coupe to the Volvo stable after a four-year absence following the departure of the 262C in 1981. The 780 became available in Europe in 1986, and would come to the United States a year later.
Like its predecessor, the 780 was designed and built by Carrozzeria Bertone in Turin, Italy. However, unlike the Volvo 262C, the 780 was not merely a two-door 760 with a "chop top" roof. Bertone gave the 780 its own distinctive shape which set it apart from the other models, yet was still identifiable as a Volvo. The car had a sleek, low profile, inheriting some of the styling of the other 700 series cars, but without many of the severe angles and sharp corners. The hood, trunk, and roof lines were all slightly lower than the standard 700 series profile, and the C-pillar was wider and had a more gradual slope down to the trunk. Headroom was improved over the 262C, due to Bertone’s mere 1 cm lowering of the roofline. Window frames all had black matte trim, and were accented with chrome. Chrome also highlighted the door handles, bumpers, and side mouldings.

In the first two years the 780 was available worldwide ('86 and '87) the 780 was available with the B280F V6 engine and a solid (live) rear axle. In the following year, they came equipped with Volvo's independent rear suspension, which used self-leveling Nivomat shocks, to keep ride height correct.

Many people began to take note of the relatively weak powerplant that the 780 had.[citation needed] The B280F at this point had roughly 150 hp (110 kW), but the car itself was nearly 3,400 lb (1,500 kg). To address concerns over performance, Volvo introduced the B230FT+; a B230FT with Volvo's boost controller, Turbo+, increasing the engine output to 175 hp (130 kW). The following model year saw it increase to 188 hp (140 kW). In Italy, 780s came with the B204GT. This was a 16 Valve Turbo motor producing 200 hp (150 kW). In the car's final year, 1991, it was rebadged simply as "Coupé". At this point, the car came only in turbo guise.

Volvo's official production total for the 780 is 8,518 cars built between 1986 and 1991. However, this number has often been disputed as different sources[clarification needed] have often estimated the actual total to be higher. As before, a coupé would remain absent from Volvo's model line for several years, until the front-wheel drive C70 was premiered in 1995 for the following model year.

Total production was more than 9,521 worldwide, but the exact total production is still unknown. 5,695 were imported to the US.

Mercedes-Benz W125





The Mercedes-Benz W125 was a Grand Prix racing car designed by Rudolf Uhlenhaut to race during the 1937 Grand Prix season. The car was used by Rudolf Caracciola to win the 1937 European Championship and W125 drivers also finished in the second, third and fourth positions in the championship.

The supercharged engine, with 8 cylinders in line (94.0 x 102.mm) and 5,662.85 cc (345.56 CID), attained an output of up to 595 horse power (444 kW) in race trim. The highest test bed power measured was 637 BHP (646 PS) at 5,800 rpm. It gave 245 BHP (248 PS) at a mere 2,000 rpm. In 1938, the engine capacity of supercharged Grand Prix cars was limited to 3000cc, and the W125 was replaced by the Mercedes-Benz W154.

The W125 was considered the most powerful race car ever for about 3 decades, until large capacity US-built V8 engines in CanAm sportcars reached similar power in the mid 1960s. In Formula One racing itself, the figure was not exceeded until the early 1980s, with the appearance of turbo-charged engines in Formula One.

The W125 reached race speeds of well over 300 km/h (190 mph) in 1937, especially on the AVUS in Berlin, equipped with a streamlined body.



In land speed record runs, a Mercedes-Benz W125 Rekordwagen was clocked at 432.7 km/h (268.9 mph) over a mile and a kilometer. This car was fitted with a DAB V12 engine (82.0 x 88 mm) of 5,576.75 cc (340.31 CID) with a power of 726 BHP (736 PS) at 5,800 rpm. The weight of this engine caused the car to weigh over the 750 kg maximum limit. So it never appeared in Grand Prix.



Concept

Due to the uncompetitiveness of their W25 car, Mercedes pulled out of the 1936 Grand Prix Season midway through the year in order to concentrate on designing a car that would see them return to the top of the rankings. A new racing department ('Rennabteilung') was set up within Mercedes-Benz in order to work on the car. Rudolf Uhlenhaut, previously a production car engineer for the company, was selected to lead the design team. Uhlenhaut had not previously designed a racing car, but had significant experience testing road cars on the Nürburgring race track, experience which allowed him to adapt his knowledge relatively easily to race cars.

When testing the old W25 car, Uhlenhaut remarked that the suspension was too stiff, preventing the wheels from following the road. During the test session, a wheel came off the car, yet Uhlenhaut continued to drive the car as if nothing had happened. This stiffness caused the chassis to flex and the rear axle to bend by up to 7-10 cm (3-4 inches) under braking. The brief for the new car included a stiffer chassis and more travel on the suspension to avoid the problems experienced in the 1936 car.
[edit] Chassis and suspension
The W125 cockpit

The W125 had a much stiffer tubular frame construction compared to the previous W25 model. This was achieved using oval tubes made of nickel-chrome molybdenum which flexed considerably less than the steel frame used in the W25.

The bodywork of the W125 was aluminium metal, which like its predecessor was left unpainted in its bare silver colour. This brought Mercedes' cars during this period (and rivals Auto Union, whose cars were the same colour) the nickname of Silver Arrows.
[edit] Engine and transmission

With no regulations limiting engine size, other than the 750 kg total car weight limit, Mercedes designed a 5.6 litre engine configured with eight inline cylinders and an overhead camshaft for the W125. Named the M125, the engine was also fitted with a Roots type supercharger producing 632 lb·ft (857 N·m) of torque at the start of the season. The engines built varied in power, attaining an output between 560 and 595 horse power (418-444 kW) at 5800 rpm. Fuel used was a custom mix of 40% methyl alcohol, 32% benzene, 24% ethyl alcohol and 4% gasoline light.[1] The engine weighed 222 kg (490 lbs) - approximately 30% of the total weight of the car, and was mounted in the front of the car.[2]

Like its W25 predecessor, the W125 used a 4-speed manual transmission. The gearbox design was changed to a constant mesh type, which provided better reliability compared to the unsynchronized transmission of the M25. In a constant mesh gearbox, the transmission gears are always in mesh and rotating, but the gears are not rigidly connected to the shafts on which they rotate. Instead, the gears can freely rotate or be locked to the shaft on which they are carried. The previous unsynchronised transmission required the gears to be spinning at roughly the same speed when engaged; otherwise, the teeth would refuse to mesh.

Racing history

The W125 made its first competitive outing in May at the 1937 Tripoli Grand Prix with Mercedes-Benz entering four cars. German Hermann Lang won his first Grand Prix motor race to give the W125 a victory on its début and provide Mercedes with their first victory over rivals Auto Union since May 1936. The next race was held at the AVUS motor-racing circuit in Germany, a 12-mile (19 km) long circuit consisting of two long straights of approximately 6 miles (10 km) length joined at either end by a curve. As such, it was possible for a car to reach its top speed. Mercedes entered two W125 cars, a streamliner which was modified from the original design to increase its top speed on the straights and a standard car driven by Richard Seaman in case of problems with the streamliner. The streamliner had a top speed 25 km/h (16 mph) faster than the regular car. On lap three of the race, the streamliner retired while leading due to a gearbox failure.

At the Eifelrennen held at the Nürburgring circuit, Mercedes entered five W125's, including one driven by Christian Kautz fitted with the new suction carburettor supercharger system. Kautz finished in ninth, while team-mates Rudolf Caracciola and Manfred von Brauchitsch finished in second and third places. For the next race, Mercedes split their entries between two races which occurred within a week of another. Two cars were sent to the USA to compete in the Vanderbilt Cup, one of which was fitted with the suction carburettor supercharger used on Kautz's car, and three cars went to Belgium to compete in the first round of the 1937 European Championship. Richard Seaman finished second in the Vanderbilt, and third and fourth place were achieved in the Belgian Grand Prix. Following Seaman's success in the Vanderbilt with the new supercharger system, it was fitted to all of the W125s.

The following two races were also both part of the European Championship. The next round in Germany saw both Mercedes and rivals Auto Union competing on home soil. Mercedes triumphed, as Rudolf Caracciola took his first victory of the year and Manfred von Brauchitsch followed him home in second position. In the next round at Monaco, the positions were reversed as von Brauchitsch won and Caracciola finished in second. A third Mercedes W125, driven by Christian Kautz, took third place.

The non-championship Coppa Acerbo in Italy was the next event the W125 entered. During practice Richard Seaman crashed into a house and destroyed his car. Therefore only von Brauchitsch and Caracciola started the race. During the race, Seaman took over from Caracciola and despite an engine fire, he finished the race fifth. von Brauchitsch fared better finishing in second position. The Swiss Grand Prix was the penultimate round of the 1937 European Championship. Like in Monaco, Mercedes W125s finished in the top three places, Caracciola taking the win with Hermann Lang in second and von Brauchitsch third. The final round of the championship marked a return to Italy, where at the Livorno Circuit, Caracciola held off team-mate Lang to win the race by 0.4 seconds and become European Champion. von Brauchitsch retired from the race and took second place overall in the Championship. Kautz and Lang took third and fourth places meaning Mercedes drivers occupied the top four positions in the championship table.

The W125 entered into two non-championship events before the end of the season. The Masaryk Grand Prix in Czechoslovakia gave the W125 its final victory when Caracciola won the race, von Brauchitsch finished second and Seaman came in third. The race was marred as Hermann Lang had crashed into spectators on lap five, resulting in twelve injuries and two deaths.

The final competitive race Mercedes entered the W125 into was the 1937 Donington Grand Prix. Rosemeyer prevailed, von Brauchitsch finished in second place and Caracciola in third while both of the other W125s failed to finish. The British ERA were outclassed, failing to get classified in their home race.
[edit] Retirement from racing

1938 saw changes in the rules, with the maximum limit on weight being replaced with a maximum limit on engine capacity and a minimum weight for the car being introduced. As such the W125 would not be eligible for entry without heavy modifications. Instead, Mercedes-Benz developed a new car, the Mercedes-Benz W154, and the W125 was withdrawn from racing.

W 154 Grand Prix


The Mercedes-Benz W154 was a Grand Prix racing car designed by Rudolf Uhlenhaut. The W154 competed in the 1938 and 1939 Grand Prix seasons and was used by Rudolf Caracciola to win the 1938 European Championship.

The W154 was created as a result of a rule change by the sports governing body AIACR, which required supercharged engine capacities to be limited to 3000cc. Mercedes' previous car, the W125 used a 5700cc engine and was therefore ineligible to be entered. Mercedes decided that a new car, designed from the outset to comply with the new regulations would be preferable to modifying the existing car and thus designed the W154.

Although using the same chassis design as the 1938 car, a different body was used for the 1939 season and the M154 engine used during 1938 was replaced by the M163. As a result of the new engine, the 1939 car is often mistakenly referred to as a Mercedes-Benz W163.

300 SL Gullwing



The Mercedes-Benz 300SL was introduced in 1954 as a two-seat, closed sports car with distinctive gull-wing doors. Later it was offered as an open roadster. It was the fastest production car of its day. That car has nickname "Gullwing" It comes from the gull-wing door and their way of opening.


Built by Daimler-Benz AG and internally numbered W198, the fuel-injected road version was based (somewhat loosely) on the company's highly successful competition-only sports car of 1952, the somewhat less powerful carbureted Mercedes-Benz 300SL (W194).



The road model was suggested by Max Hoffman. Being intended for customers in the booming post-war American market it was introduced at the 1954 New York Auto Show, unlike previous models introduced at either the Frankfurt or Geneva shows. In Mercedes-Benz fashion, the "300" referred to the engine's three litre cylinder displacement. The "SL" stood for "Sport Leicht" (Sport Light).

The 300SL was best known for both its distinctive gull wing doors and being the first-ever gasoline-powered car equipped with fuel injection directly into the combustion chamber. The gull wing version was available from March 1955 to 1957. Production of the roadster ended in 1963 with the introduction of the 230SL.

A race car for the street

New York Mercedes distributor Max Hoffman, Daimler-Benz's official importer in the USA, suggested to DBAG management in Stuttgart that a street version of the 300SL would be a commercial success, especially in America.

The racing W194 300SL was built around a tubular chassis to offset its relatively underpowered carbureted engine. Designed by DBAG's chief developing engineer, Rudolf Uhlenhaut, the metal skeleton saved weight while still providing a high level of strength. Its unique architecture gave birth to the model's distinctive gull wing doors, as part of the chassis passed through what would be the lower half of a standard door. Even with the upward opening doors, the 300SL had an unusually high sill, making entry and exit from the car's cockpit problematic. A steering wheel with a tilt-away column was added to improve driver access.

The 300SL's body was mainly steel, except for the aluminum hood, doors and trunk lid. It could also be ordered with an all-aluminium outer skin at tremendous added cost, saving 80 kg (176 lb).

More than 80% of the vehicle's total production of approximately 1400 units were sold in the US, making the Gull wing the first Mercedes-Benz which sold in bulk outside its home market and confirming the validity of Hoffman's suggestion. The 300SL is credited for changing the company's image in America from a manufacturer of solid, but staid, automobiles to that of a producer of sporty cars.

The 300SL's engine, canted at a fifty-degree angle to the left to allow for a lower hoodline, was the same 3.0 litre straight-6 as the regular four-door 300. Fitted with a Bosch mechanical direct fuel injection system it had almost double the power of the original 86 kW (115 hp) carbureted version.

While not the first fuel-injected car - Mercedes engineers who had developed the principle for the DB 601 fighter aircraft engine had used fuel injection in the tiny 2-stroke Gutbrod they had designed after the War - it was the first to inject fuel directly into the cylinders. This innovation allowed a top speed of up to 260 km/h (161 mph) depending on gear ratio and drag, making the 300SL the fastest production car of its time.

The engine's maintenance requirements were high. Unlike the current electrically-powered fuel injection systems, the mechanical fuel pump would continue to inject gasoline into the engine during the interval between shutting off the ignition and the engine's coming to a stop; this gasoline was of course not burned, and washed the oil from the cylinder walls and ended up diluting the engine's lubricating oil, particularly if the engine was not driven hard enough nor long enough to reach a temperature high enough to evaporate it out of the oil.

Exacerbating the problem were the large oil cooler as well as the large volume of oil (10 liters), both oriented more to racing than to street driving, which virtually guaranteed that the oil would not reach a high enough temperature. In practice, many street drivers would block off airflow through the oil cooler, and the recommended oil change interval was 1,000 miles (1,600 km). Operation of the clutch was initially very heavy, later roadster having an improved clutch arm helper spring which reduced the pedal force. From March 1963 to the end of production, a light alloy crankcase was used on a total of 209 vehicles.[2]

Aerodynamics played an important role in the car's speed, Mercedes-Benz engineers even placing horizontal "eyebrows" over the wheel openings to reduce drag. Unlike many cars of the 1950s, the steering was relatively precise and the four-wheel independent suspension allowed for a reasonably comfortable ride and markedly better overall handling. However, the rear swing axle, jointed only at the differential, not at the wheels themselves, could be treacherous at high speeds or on imperfect roads due to extreme changes in camber.

Mercedes C112



The Mercedes-Benz C112 was an experimental mid-engined sportscar created in 1991 by Mercedes-Benz as a test bed, similar to the later versions of the Mercedes-Benz C111. Despite using the same number, it was not related to the 1960s Mercedes-Benz W112 series of limousines and coupes of the 1960s. The C112 also was a road-legal counterpart for the Sauber-built Mercedes-Benz C11 Group C prototype race car for the 1990 World Sportscar Championship.

The C112 which also featured gullwing doors was equipped with the new 6.0-litre V12 engine, with the standard 300 kW (408 hp) and peak torque of 580 Nm. The major systems tested on this vehicle were:

Active Body Control

This was designed to control the vehicles stability through a combination of active springs and hydraulics at each wheel, plus sensors that monitor the vehicle’s movements. The vehicles computer assesses the information from the sensors and adjusts the suspension accordingly.

Other systems

The most recent updates in anti-locking braking (ABS) and anti-skid control system (ASR) which split the braking pressure between the front and rear wheels

Active Aerodynamics

This was provided through the cars front spoiler and rear wing which could be moved to ensure the optimum combination of low drag and high downforce. The rear wing was also used to improve the car's braking in emergency situations. Although this was not seen in production until the Mercedes-Benz SLR McLaren.

Even though Mercedes-Benz received 700 orders for the car it never went into production

Lamborghini Jalpa (1982)



Evolving from the Urraco, Jalpa was the cheapest Lamborghini in the 80s intending to compete with Ferrari 308 / 328GTB. It looked unique, if not really beautiful. Powered by a 3.5-litre V8 (with 2 valves / cylinder only), it had similar performance to match with the Ferraris. Handling and roadholding were also up to Ferrari’s league.

In fact, this car was larger than the Countach in all dimensions bar width. Besides, since it was built as a monocoque structure rather than spaceframe, it did not have the wide and high door sills as featured in Countach. Therefore cabin room was rather generous for 2 occupants. Furthermore, fine leather trimming, Targa roof and large storage space enabled it to attract more mainstream customers.

Nevertheless, it still lived under the shadow of Ferrari 328GTB, since the latter was marginally better in nearly all aspects. As a result, production terminated in the late 80s.

Lamborghini Urraco (1974)




Urraro was an ambitious project. Ferruccio Lamborghini wanted this car to be sold at a rate of 2,000 units per year, which made Lamborghini the Porsche of Italy. However, hit by the energy crisis, Urraco found itself born in the wrong time. The project failed completely.

In technical view, Urraco was quite interesting. It was a mid-engined sports car, but simultaneously had 2+2 seating layout. That made it the first 2+2 mid-engined car in the world, even earlier than Ferrari 308GT4. The original car was powered by an underpowered sohc 2.5-litre V8, then upgraded to dohc 3-litre V8 and the new car was called Urraco P300 (compared with the original P250).

P300 was an excellent GT, with sensuous handling accompanied with excellent brakes. Between 1974 and 1976, only 776 Urracos were made, which was well below Lamborghini's expectation. After that, it was modified to Silhouette (more like a Urraco with Targa roof) and eventually became the 2-seat Jalpa. What a pity a good car died in this way.

Lamborghini Espada (1968)




Espada was the only 4-seater that Lamborghini had ever produced. Based on an all-new semi-monocoque chassis, it was long enough to accommodate 2 more adults with comfort, that made it the roomiest GT.

Apart from space, its drivetrain also gave it advantages over rivals from Ferrari and Maserati. Engine came from the familiar 400GT, which displaced 3.9 litres and mounted in front rather than rear as the prototype. In debut, 320 hp was available, but a couple of years later it was improved to 350 hp by raising compression ratio from 9.5 to 10.7 to 1. Power transferred to a slick changing ZF five-speed box. As a whole, these combinations provided a healthy 52:48 front-to-rear weight distribution. Therefore the Espada was praised for powerful, relatively easy to operate and had a good road manner, while the only drawback was the Italian-styled driving position.

Espada was the second most successful classic Lamborghini in terms of sales. 1,217 Espadas were built between 1968 and 1978. If not hit by the company’s financial crisis, it would have survived longer.
