Audi Quattro
The 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.[1][3] Production continued through 1991.

The word quattro is derived from the Italian word for "four" to represent the fact that the vehicle delivers power to all four wheels. 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. The original Quattro model is also commonly referred to as the Ur-Quattro - the "Ur-" (German for "primordial", "original", or "first of its kind") is an augmentative prefix. The idea of such a car came from the Audi engineer Jörg Bensinger.
The Audi Quattro was the first rally car to take advantage of the then-recently changed rules that allowed the use of four-wheel drive in competition racing. It won consecutive competitions for the next two years.[4] To commemorate the success of the original vehicle, all subsequent Audi production automobiles with this four-wheel-drive system were badged with the trademark quattro with a lower case "q" letter.
The Audi Quattro shared many parts and platform with the Coupé version of the Audi 80 (B2).[4] The quattro was internally designated Typ 85, a production code it shared with the quattro versions of the Audi Coupé. Its characteristic flared wheelarches were styled by Martin Smith. The Audi Quattro also had independent front and rear suspension.[5][6]
The idea for a high-performance four-wheel-drive car was proposed in 1977 by Audi's chassis engineer, Jörg Bensinger, after he found that the Volkswagen Iltis military vehicle could outperform other vehicles when tested in the snow. An Audi 80 variant was developed in co-operation with Walter Treser, Director of Pre-Development.[7][8]
Audi introduced the original Quattro to European customers in late 1980,[4] featuring Audi's quattro permanent four-wheel drive system, and the first to mate the front-engine, four-wheel-drive layout with a turbocharged engine.[4]
The original engine was the 2,144 cc (2.1 L), longitudinally-mounted inline-5-cylinder 10 valve SOHC, with a turbocharger and intercooler. It generated 147 kW (200 PS; 197 hp) and torque of 285 N⋅m (210 lbf⋅ft) at 3,500 rpm, propelling the Quattro from 0 to 100 km/h (62 mph) in 7.1 seconds, and on to a top speed of over 220 km/h (137 mph).[4]
The displacement of the engine was dropped slightly from 2144 cc to 2133 cc with a bore x stroke of 79.3 mm × 86.4 mm (3.1 in × 3.4 in) for the Rally car so that Audi could satisfy the 3-litre rallying class with a 1.4 times multiplication factor. Valvetrain was DOHC 4 valves per cylinder (20 valves in total) with an oil cooled KKK K27 turbocharger at 1.03 bars (14.9 psi) and Air-to-Air - Längerer & Reich intercooler fed by Bosch LH-Jetronic fuel injection, generating 225 kW (306 PS; 302 hp) at 6,700 rpm and 350 N⋅m (258 lbf⋅ft) of torque at 3,700 rpm.[9]
The engine was eventually modified to a 2,226 cc (136 cu in) inline-5 with 10 valves, still generating 147 kW (200 PS; 197 hp), but with peak torque lower in the rev-range.[4] In 1989, it was then changed to a 2,226 cc (136 cu in) inline-five 20-valve DOHC setup generating 162 kW (220 PS; 217 hp), now with a top speed of 230 km/h (143 mph).[4]

The Quattro was partially hand-built on a dedicated line.[8] Production totaled 11,452 units from 1980 to 1991,[4][3] and through this 11 year production there were no major changes in the visual design of the car. For the 1983 model year, the dashboard did away with an analogue instrument cluster now fitted with 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 new dashboard layout, new steering wheel design, and new centre console design, the switches around the instrument panel were also redesigned. In 1985, the dashboard changed slightly with harder foam and it lost a diagonal stripe, the switches were varied slightly and the diff lock pull knob gave way to a two-position turn knob with volt and oil temp digital readouts.

Exterior styling received little modification during the Quattro's production run. Originally, the car had a flat front grille featuring four separate headlamp lenses, one for each of the low and high beam units. This was altered for the 1983 model year with combined units featuring a single lens 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.[2] The 20V RR Quattro also featured a new three-spoke steering wheel design, leather trim 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 and 'quattro' script on the interior with partial leather seats. The floor on the driver's 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-inch with 205/60-15 tyres to 8x15-inch wheels with 215/50-15 Pirelli Cinturato P5 tyres. At the same time the suspension was lowered by 20 mm 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.[4]
The last original Audi Quattro was produced on 17 May 1991, more than two years after the first models of the new Audi Coupé (8B) range (based on the 1986 Audi 80) had been introduced.[10]
Sales of the Quattro in North America began in the 1983 model year.[11] They entered the all-wheel-drive market established by the AMC Eagle, the first full-time automatic all-wheel-drive line of passenger cars to reach mass production.[12][13] The small Subaru Leone station wagon offered an optional part-time 4-wheel drive system in the US market starting in 1975.[14]
The North American Quattro was manufactured concurrently and were of the same design as their European 1982 model year counterparts (they did not include the minor cosmetic changes of the 1983 European model) and continued through 1986. Total sales in the U.S. totalled 664 units. The Canadian market cars were identical to the U.S. version with exception of the speedometer, which was metric. Official sales figures for Canada were 99 units, which included 61 sold in 1983, 17 sold in 1984, 18 sold in 1985, and 3 sold in 1986.
The U.S./Canadian cars were equipped with larger impact bumpers with built-in shock absorbers, like the rest of the 4000/Coupé models. They did not have anti-lock braking system (ABS), but included air conditioning and leather upholstery. Most of the 1984 and 1985 Canadian models came without sunroofs. The remainder of the electric, suspension, and cosmetic updates took place at the same time as the European cars.
The initial 2.1 L (2,144 cc, engine code "WX") engine for U.S./Canadian models included minor component and engine control unit (ECU) changes, lowered turbocharger boost pressure, different camshaft, as well as emission controls that consisted of a catalytic converter and fuel control giving a stoichiometric air-fuel ratio, lowering power output to 160 hp (119 kW; 162 PS). Other mechanical specifications were identical to the European market vehicles. The WX engine was also utilized in Swiss and Japanese market cars. Audi built 200 special edition cars in 1988 with the WX engine and analogue instrument cluster, with everything else identical to the MB model of that year.
In May 1981, Autocar magazine road tested a left hand drive Quattro (registration number WBD 335W), one of the first magazines to do so since it was introduced. Beginning with a photograph in the magazine of a Quattro cornering hard on Pendine beach in South-west Wales, Autocar's Road Test Editor raved about the Quattro's "thrilling performance" being impressed with its traction and acceleration particularly on wet, greasy and slippery surfaces, noting that only the Porsche 911 could match its traction and acceleration in slippery conditions. After extensive driving across the mountain roads of Wales, the Road Test editor mentioned that while the 60/40 front/rear weight distribution can make the Quattro "tricky in extremis" under very hard cornering, the editor wrote that "When driven with respect, once you have learned its ways, the Quattro is nevertheless magnificent, particularly through a wet and deserted roundabout or series of open bends." The road test editor praised the interior's "comfortable refinement" and judged that its 1981 £14,500 price tag "is very good value for money considering its performance and the fact that its BMW, Porsche and Jaguar rivals cost £5000 more." (In summer 1981 both a Jaguar XJS V12 and BMW 6 Series Coupe on sale in the UK cost almost £20,000). Adding the caveat that in 1981 (and until summer 1983) the Quattro was only available in left hand drive in the UK, the Autocar Road Test concluded that the Quattro "is a vastly satisfying and enjoyable car to drive."
The Audi quattro Spyder was a mid-engine coupé equipped with a 2.8-litre V6 engine taken from the Audi 100. The engine was rated at 174 PS (128 kW; 172 hp) and 181 lb⋅ft (245 N⋅m) of torque. The car was a rolling test bed for a future mid-engine sports car and featured a 5-speed manual gearbox, a modified version for the quattro four-wheel-drive system, aluminium body panels with a tubular steel space frame, 1,100 kg (2,425 lb) kerb weight and a suspension system with trapezoidal links. All of the unique features depicted in the concept car would find their way in future Audi production vehicles.
The car was production-ready and garnered a lot of acclaim from both the motoring press and prospective buyers but due to the economic downturn of the 1990s, Audi decided not to press ahead with the project as the demand would not outweigh the development costs for the model.
The concept car was unveiled at the 1991 Frankfurt Motor Show
Audi AG (German: [ˈaʊ̯di ʔaːˈɡeː] ) is a German automotive manufacturer of luxury vehicles headquartered in Ingolstadt, Bavaria, Germany. A subsidiary of the Volkswagen Group, Audi produces vehicles in nine production facilities worldwide.
The origins of the company are complex, dating back to the early 20th century and the initial enterprises (Horch and the Audiwerke) founded by engineer August Horch (1868–1951). Two other manufacturers (DKW and Wanderer) also contributed to the foundation of Auto Union in 1932. The modern Audi era began in the 1960s, when Auto Union was acquired by Volkswagen from Daimler-Benz.[9] After relaunching the Audi brand with the 1965 introduction of the Audi F103 series, Volkswagen merged Auto Union with NSU Motorenwerke in 1969, thus creating the present-day form of the company.
The company name is based on the Latin translation of the surname of the founder, August Horch. Horch, meaning 'listen', becomes audi in Latin. The four rings of the Audi logo each represent one of four car companies that banded together to create Audi's predecessor company, Auto Union. Audi's slogan is Vorsprung durch Technik, which is translated as 'Progress through Technology'.[10] Audi, along with German brands BMW and Mercedes-Benz, is among the best-selling luxury automobile brands in the world.[11]
Automobile company Wanderer was originally established in 1885, later becoming a branch of Audi AG. Another company, NSU, which also later merged into Audi, was founded during this time, and later supplied the chassis for Gottlieb Daimler's four-wheeler.[12]
On 14 November 1899, August Horch (1868–1951) established the company A. Horch & Cie. in the Ehrenfeld district of Cologne. In 1902, he moved with his company to Reichenbach im Vogtland. On 10 May 1904, he founded the August Horch & Cie. Motorwagenwerke AG, a joint-stock company in Zwickau (State of Saxony).
After troubles with Horch chief financial officer, August Horch left Motorwagenwerke and founded in Zwickau on 16 July 1909, his second company, the August Horch Automobilwerke GmbH. His former partners sued him for trademark infringement. The German Reichsgericht (Supreme Court) in Leipzig,[13] eventually determined that the Horch brand belonged to his former company.[14]

Since August Horch was prohibited from using horch as a trade name in his new car business, he called a meeting with close 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?".[15] Horch in German means 'hark' or 'hear', which is audi in the singular imperative form of audire—'to listen'—in Latin. The idea was enthusiastically accepted by everyone attending the meeting.[16] On 25 April 1910 the Audi Automobilwerke GmbH Zwickau (from 1915 on Audiwerke AG Zwickau) was entered in the company's register of Zwickau registration court.
The first Audi automobile, the Audi Type A 10/22 hp (16 kW) Sport-Phaeton, was produced in the same year,[17] followed by the successor Type B 10/28PS in the same year.[18]
Audi started with a 2,612 cc inline-four engine model Type A, followed by a 3,564 cc model, as well as 4,680 cc and 5,720 cc models. These cars were successful even in sporting events. The first six-cylinder model Type M, 4,655 cc appeared in 1924.[19]
August Horch left the Audiwerke 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.[20] Left-hand drive spread and established dominance during the 1920s because it provided a better view of oncoming traffic, making overtaking safer[20] when driving on the right.
In August 1928, Jørgen Rasmussen, the owner of Dampf-Kraft-Wagen (DKW), acquired the majority of shares in Audiwerke AG.[21] In the same year, Rasmussen bought the remains of the U.S. automobile manufacturer Rickenbacker, including the manufacturing equipment for 8-cylinder engines. These engines were used in Audi Zwickau and Audi Dresden models that were launched in 1929. At the same time, 6-cylinder and 4-cylinder (the "four" with a Peugeot engine) 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 AG, Chemnitz. It was during this period that the company offered the Audi Front that became the first European car to combine a six-cylinder engine with front-wheel drive. It used a power train shared with the Wanderer, but turned 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. However, this badge was used 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%. After the final few Audis were delivered in 1939 the "Audi" name disappeared completely from the new car market for more than two decades.
Richard Bruhn, a Nazi party member, was Auto Union’s Chairman of the Board from 1932 to 1945 and then again after the war when the company was reestablished. In 2014 Audi became the last major German car company, after Volkswagen, BMW and Daimler, to commission a study of their wartime activities.[22] The investigation found that the company worked with the SS to build seven labor camps where more than 3,700 prisoners were put to work for Auto Union.[23] In addition, 16,500 more people were forced to work at the company's factories in Zwickau and Chemnitz, and another 18,000 at an underground plant in Bavaria where 4,500 people died.[22]
Some of the company's factories were bombed by the Allies.[citation needed]

With no prospect of continuing production in Soviet-controlled East Germany, Auto Union executives began the process of relocating what was left of the company to West Germany.[citation needed] A site was chosen in Ingolstadt, Bavaria, to start a spare parts operation in late 1945, which would eventually serve as the headquarters of the reformed Auto Union in 1949.[citation needed]
On 17 August 1948, Auto Union AG of Chemnitz was deleted from the commercial register.[21] 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 [de] or AWZ (in English: Automobile Works Zwickau).
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. The Zwickau plant later manufactured the infamous Trabant until 1991, after it was acquired by the Volkswagen Group following the reunification of Germany, and has since been substantially rebuilt. In 2021, production of the Audi Q4 e-tron began at the plant, marking the return of Audis being manufactured at Zwickau after over 80 years.
A new West German headquartered Auto Union was launched in Ingolstadt with loans from the Bavarian state government and Marshall Plan aid.[24] The reformed company was launched 3 September 1949 and continued DKW's tradition of producing front-wheel drive vehicles with two-stroke engines.[24] This included production of a small but sturdy 125 cc motorcycle and a DKW delivery van, the DKW F89 L at Ingolstadt. The Ingolstadt site was large, 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 an investor, when funds became available for construction of major car plant at the Ingolstadt head office site.
In 1958, in response to pressure from Friedrich Flick, then the company's largest single shareholder,[25] 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 Daimler-Benz'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. The decision to dispose of the Auto Union business was based on its lack of profitability.[26] Ironically, by the time they sold the business, it also included a large new factory and near production-ready modern four-stroke engine, which would enable the Auto Union business, under a new owner, to embark on a period of profitable growth, now producing not Auto Unions or DKWs, but using the "Audi" name, resurrected in 1965 after a 25-year gap.
In 1964, Volkswagen acquired a 50% holding in the business, which included the new factory in Ingolstadt, the DKW and Audi brands along with the rights to the new engine design which had been funded by Daimler-Benz, who in return retained the dormant Horch trademark and the Düsseldorf factory which became a Mercedes-Benz van assembly plant. Eighteen 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.[27] 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 was fitted with a four-stroke engine and a facelift for the car's front and rear. 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 after their horsepower ratings and sold as the Audi 60, 75, 80, and Super 90, selling until 1972. Initially, Volkswagen was hostile to the idea of Auto Union as a standalone entity producing its own models having acquired the company merely to boost its own production capacity through the Ingolstadt assembly plant—to the point where Volkswagen executives ordered that the Auto Union name and flags bearing the four rings were removed from the factory buildings. Then VW chief Heinz Nordhoff explicitly forbade Auto Union from any further product development. Fearing that Volkswagen had no long-term ambition for the Audi brand, Auto Union engineers under the leadership of Ludwig Kraus developed the first Audi 100 in secret, without Nordhoff's knowledge. When presented with a finished prototype, Nordhoff was so impressed he authorised the car for production, which when launched in 1968, went on to be a huge success. With this, the resurrection of the Audi brand was now complete, this being followed by the first generation Audi 80 in 1972, which would in turn provide a template for VW's new front-wheel-drive water-cooled range which debuted from the mid-1970s onward.
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 car well ahead of its time in technical details such as aerodynamics, light weight, and safety. However, teething problems with the rotary engines put an end to the independence of NSU. The Neckarsulm plant is now used to produce the larger Audi models A6 and A8. The Neckarsulm factory is also home of the "quattro GmbH" (from November 2016 "Audi Sport GmbH"), a subsidiary responsible for development and production of Audi high-performance models: the R8 and the RS model range.
The new merged company was incorporated on 1 January 1969 and was known as Audi NSU Auto Union AG, with its headquarters at NSU's Neckarsulm plant, 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. That same year, the mid-sized car that NSU had been working on, the K70, originally intended to slot between the rear-engined Prinz models and the futuristic NSU Ro 80, was instead launched as a Volkswagen.
After the launch of the Audi 100 of 1968, the Audi 80/Fox (which formed the basis for the 1973 Volkswagen Passat) followed in 1972 and the Audi 50 (later rebadged as the Volkswagen Polo) in 1974. The Audi 50 was a seminal design because it was the first incarnation of the Golf/Polo concept, one that led to a hugely successful world car. Ultimately, the Audi 80 and 100 (progenitors of the A4 and A6, respectively) became the company's biggest sellers, whilst little investment was made in the fading NSU range; the Prinz models were dropped in 1973 whilst the fatally flawed NSU Ro80 went out of production in 1977, spelling the effective end of the NSU brand. Production of the Audi 100 had been steadily moved from Ingolstadt to Neckarsulm as the 1970s had progressed, and by the appearance of the second generation C2 version in 1976, all production was now at the former NSU plant. Neckarsulm from that point onward would produce Audi's higher-end models.
The Audi image at this time was a conservative one, and so, a proposal from chassis engineer Jörg Bensinger[28] 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 Saloons, 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.
In 1985, with the Auto Union and NSU brands effectively dead, the company's official name was now shortened to simply Audi AG. At the same time the company's headquarters moved back to Ingolstadt and two new wholly owned subsidiaries; Auto Union GmbH and NSU GmbH, were formed to own and manage the historical trademarks and intellectual property of the original constituent companies (the exception being Horch, which had been retained by Daimler-Benz after the VW takeover), and to operate Audi's heritage operations.
In 1986, as the Passat-based Audi 80 was beginning to develop a kind of "grandfather's car" image, the type 89 was introduced. This completely new development sold extremely well. However, its modern and dynamic exterior belied the low performance of its base engine, and its base package was quite spartan (even the passenger-side mirror was an option). In 1987, Audi put forward a new and very elegant Audi 90, which had a much superior set of standard features. In the early 1990s, sales began to slump for the Audi 80 series, and some basic construction problems started to surface.
Through the early 1990s, Audi began to shift its target market upscale to compete against German automakers Mercedes-Benz and BMW. This began with the release of the Audi V8 in 1990. It was essentially a new engine fitted to the Audi 100/200, but with noticeable bodywork differences. Most obvious was the new grille that was now incorporated in the bonnet.
By 1991, Audi had the four-cylinder Audi 80, the 5-cylinder Audi 90 and Audi 100, the turbocharged Audi 200 and the Audi V8. There was also a coupé version of the 80/90 with both four- and five-cylinder engines.
Although the five-cylinder engine was a successful and robust powerplant, it was still a little too different for the target market. With the introduction of an all-new Audi 100 in 1992, Audi introduced a 2.8L V6 engine. This engine was also fitted to a face-lifted Audi 80 (all 80 and 90 models were now badged 80 except for the USA), giving this model a choice of four-, five-, and six-cylinder engines, in saloon, coupé and convertible body styles.
The five-cylinder was soon dropped as a major engine choice; however, a turbocharged 220 PS (160 kW; 220 hp) version remained. The engine, initially fitted to the 200 quattro 20V of 1991, was a derivative of the engine fitted to the Sport Quattro. It was fitted to the Audi Coupé, named the S2, and also to the Audi 100 body, and named the S4. These two models were the beginning of the mass-produced S series of performance cars.
Sales in the United States fell after a series of recalls from 1982 to 1987 of Audi 5000 models[29] associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents.[29] At the time, NHTSA was investigating 50 car models from 20 manufacturers for sudden surges of power.[30]
A 60 Minutes report aired 23 November 1986,[31] featuring interviews with six people who had sued Audi after reporting unintended acceleration, showing an Audi 5000 ostensibly suffering a problem when the brake pedal was pushed.[32][33] Subsequent investigation revealed that 60 Minutes had engineered the failure—fitting a canister of compressed air on the passenger-side floor, linked via a hose to a hole drilled into the transmission.[31]
_(10629216834).jpg)
Audi contended, prior to findings by outside investigators,[30] that the problems were caused by driver error, specifically pedal misapplication.[30] Subsequently, the National Highway Traffic Safety Administration (NHTSA) concluded that the majority of unintended acceleration cases, including all the ones that prompted the 60 Minutes report, were caused by driver error such as confusion of pedals.[34] CBS did not acknowledge the test results of involved government agencies, but did acknowledge the similar results of another study.[32]
In a review study published in 2012, NHTSA summarized its past findings about the Audi unintended acceleration problems: "Once an unintended acceleration had begun, in the Audi 5000, due to a failure in the idle-stabilizer system (producing an initial acceleration of 0.3g), pedal misapplication resulting from panic, confusion, or unfamiliarity with the Audi 5000 contributed to the severity of the incident."[35]
This summary is consistent with the conclusions of NHTSA's most technical analysis at the time: "Audi idle-stabilization systems were prone to defects which resulted in excessive idle speeds and brief unanticipated accelerations of up to 0.3g [which is similar in magnitude to an emergency stop in a subway car]. These accelerations could not be the sole cause of [(long-duration) sudden acceleration incidents (SAI)], but might have triggered some SAIs by startling the driver.[36] The defective idle-stabilization system performed a type of electronic throttle control. Significantly: multiple "intermittent malfunctions of the electronic control unit were observed and recorded ... and [were also observed and] reported by Transport Canada."[36]
With a series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models.[29] Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park.[29] A legacy of the Audi 5000 and other reported cases of sudden unintended acceleration are intricate gear stick patterns and brake interlock mechanisms to prevent inadvertent shifting into forward or reverse. It is unclear how the defects in the idle-stabilization system were addressed.
Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years,[29]—with resale values falling dramatically.[37] Audi subsequently offered increased warranty protection[37] and renamed the affected models—with the 5000 becoming the 100 and 200 in 1989[30]—and reached the same sales levels again only by model year 2000.[29]
A 2010 BusinessWeek article—outlining possible parallels between Audi's experience and 2009–2010 Toyota vehicle recalls—noted a class-action lawsuit filed in 1987 by about 7,500 Audi 5000-model owners remains unsettled and remains contested in Chicago's Cook County after appeals at the Illinois state and U.S. federal levels.[29]
In the mid-to-late 1990s, Audi introduced new technologies including the use of aluminium construction. Produced from 1999 to 2005, the Audi A2 was a futuristic super mini, born from the Al2 concept, with many features that helped regain consumer confidence, like the aluminium space frame, which was a first in production car design. In the A2 Audi further expanded their TDI technology through the use of frugal three-cylinder engines. The A2 was extremely aerodynamic and was designed around a wind tunnel. The Audi A2 was criticised for its high price and was never really a sales success but it planted Audi as a cutting-edge manufacturer. The model, a Mercedes-Benz A-Class competitor, sold relatively well in Europe. However, the A2 was discontinued in 2005 and Audi decided not to develop an immediate replacement.
The next major model change came in 1995 when the Audi A4 replaced the Audi 80. The new nomenclature scheme was applied to the Audi 100 to become the Audi A6 (with a minor facelift). This also meant the S4 became the S6 and a new S4 was introduced in the A4 body. The S2 was discontinued. The Audi Cabriolet continued on (based on the Audi 80 platform) until 1999, gaining the engine upgrades along the way. A new A3 hatchback model (sharing the Volkswagen Golf Mk4's platform) was introduced to the range in 1996, and the radical Audi TT coupé and roadster were debuted in 1998 based on the same underpinnings.
The petrol engines available throughout the range were now a 1.4 L, 1.6 L and 1.8 L four-cylinder, 1.8 L four-cylinder turbo, 2.6 L and 2.8 L V6, 2.2 L turbo-charged five-cylinder and the 4.2 L V8 engine. The V6s were replaced by new 2.4 L and 2.8 L 30V V6s in 1998, with marked improvement in power, torque and smoothness. Further engines were added along the way, including a 3.7 L V8 and 6.0 L W12 engine for the A8.
Audi's sales grew strongly in the 2000s, with deliveries to customers increasing from 653,000 in 2000 to 1,003,000 in 2008. The largest sales increases came from Eastern Europe (+19.3%), Africa (+17.2%) and the Middle East (+58.5%). China in particular has become a key market, representing 108,000 out of 705,000 cars delivered in the first three quarters of 2009. One factor for its popularity in China is that Audis have become the car of choice for purchase by the Chinese government for officials, and purchases by the government are responsible for 20% of its sales in China.[38] As of late 2009, Audi's operating profit of €1.17 billion ($1.85 billion) made it the biggest contributor to parent Volkswagen Group's nine-month operating profit of €1.5 billion, while the other marques in Group such as Bentley and SEAT had suffered considerable losses.[39] May 2011 saw record sales for Audi of America with the new Audi A7 and Audi A3 TDI Clean Diesel.[40] In May 2012, Audi reported a 10% increase in its sales—from 408 units to 480 in the last year alone.[41]
Audi manufactures vehicles in seven plants around the world, some of which are shared with other VW Group marques[42] although many sub-assemblies such as engines and transmissions are manufactured within other Volkswagen Group plants.
Audi's two principal assembly plants in Germany are:
- Ingolstadt, the former Auto Union site originally opened in 1945 and substantially rebuilt by Daimler-Benz in 1962, and acquired by Volkswagen in 1964 (Q2, A3, A4, A5)
- Neckarsulm, the former NSU plant, acquired by Volkswagen in 1969: (A4, A5 (cabrio), A6, A7, A8, R8, and all RS variants) - a satellite plant at nearby Böllinger Höfe produces the e-tron GT
Outside of Germany, Audi produces vehicles at:
- Aurangabad, India, since 2006
- Bratislava, Slovakia, shared with Volkswagen, SEAT, Škoda and Porsche (Q7 and Q8)
- Brussels, Belgium, acquired from Volkswagen in 2007 (e-tron)
- Changchun, China, since 1995
- Győr, Hungary (TT, A3, Q3)
- Jakarta, Indonesia, since 2011
- Martorell, Spain, shared with SEAT and Volkswagen (A1, Q3)
- San José Chiapa, Mexico (2nd gen Q5)
In September 2012, Audi announced the construction of its first North American manufacturing plant in Puebla, Mexico. This plant became operative in 2016 and produces the second generation Q5.[43]
From 2002 up to 2003, Audi headed the Audi Brand Group, a subdivision of the Volkswagen Group's Automotive Division consisting of Audi, Lamborghini and SEAT, which was focused on sporty values, with the marques' product vehicles and performance being under the higher responsibility of the Audi brand.
In January 2014, Audi, along with the Wireless Power Consortium, operated a booth which demonstrated a phone compartment using the Qi open interface standard at the Consumer Electronics Show (CES).[44] In May, most of the Audi dealers in the UK falsely claimed that the Audi A7, A8, and R8 were Euro NCAP safety tested, all achieving five out of five stars. In fact none were tested.[45]
In 2015, Audi admitted that at least 2.1 million Audi cars had been involved in the Volkswagen emissions testing scandal in which software installed in the cars manipulated emissions data to fool regulators and allow the cars to pollute at higher than government-mandated levels. The A1, A3, A4, A5, A6, TT, Q3 and Q5 models were implicated in the scandal.[46] Audi promised to quickly find a technical solution and upgrade the cars so they can function within emissions regulations.[47] Ulrich Hackenberg, the head of research and development at Audi, was suspended in relation to the scandal.[48] Despite widespread media coverage about the scandal through the month of September, Audi reported that U.S. sales for the month had increased by 16.2%.[49] Audi's parent company Volkswagen announced on 18 June 2018 that Audi chief executive Rupert Stadler had been arrested.[50]
In November 2015, the U.S. Environmental Protection Agency implicated the 3-liter diesel engine versions of the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and the Q5 as further models that had emissions regulation defeat-device software installed.[51] Thus, these models emitted nitrogen oxide at up to nine times the legal limit when the car detected that it was not hooked up to emissions testing equipment.[52]
In November 2016, Audi expressed an intention to establish an assembly factory in Pakistan, with the company's local partner acquiring land for a plant in Korangi Creek Industrial Park in Karachi. Approval of the plan would lead to an investment of $30 million in the new plant.[53] Audi planned to cut 9,500 jobs in Germany starting from 2020 till 2025 to fund electric vehicles and digital working.[54]
In February 2020, Volkswagen AG announced that it plans to take over all Audi shares it does not own (totalling 0.36%) via a squeeze-out according to German stock corporation law, thus making Audi a fully owned subsidiary of the Volkswagen Group.[55] This change took effect from 16 November 2020, when Audi became a wholly owned subsidiary of the Volkswagen Group.[56]
In January 2021, Audi announced that it is planning to sell 1 million vehicles in China in 2023, comparing to 726,000 vehicles in 2020.[57]
Audi AI is a driver assist feature offered by Audi. The company's stated intent is to offer fully autonomous driving at a future time, acknowledging that legal, regulatory and technical hurdles must be overcome to achieve this goal. On 4 June 2017, Audi stated that its new A8 will be fully self-driving for speeds up to 60 km/h using its Audi AI. Contrary to other cars, the driver will not have to do safety checks such as touching the steering wheel every 15 seconds to use this feature. The Audi A8 will therefore be the first production car to reach level 3 autonomous driving, meaning that the driver can safely turn their attention away from driving tasks, e.g. the driver can text or watch a movie. Audi will also be the first manufacturer to use a 3D Lidar system in addition to cameras and ultrasonic sensors for their AI.[58][59]
Audi produces 100% galvanised cars to prevent corrosion,[60] and was the first mass-market vehicle to do so, following introduction of the process by Porsche, c. 1975. Along with other precautionary measures, the full-body zinc coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year warranty against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust).[61]

Audi introduced a new series of vehicles in the mid-1990s and continues to pursue new technology and high performance. An all-aluminium car was brought forward by Audi, and in 1994 the Audi A8 was launched, which introduced aluminium space frame technology (called Audi Space Frame or ASF) which saves weight and improves torsion rigidity compared to a conventional steel frame. Prior to that effort, Audi used examples of the Type 44 chassis fabricated out of aluminium as test-beds for the technique. The disadvantage of the aluminium frame is that it is very expensive to repair and requires a specialized aluminium bodyshop.[62] The weight reduction is somewhat offset by the quattro four-wheel drive system which is standard in most markets. Nonetheless, the A8 is usually the lightest all-wheel drive car in the full-size luxury segment, also having best-in-class fuel economy.[63] The Audi A2, Audi TT and Audi R8 also use Audi Space Frame designs.
For most of its lineup (excluding the A3, A1, and TT models), Audi has not adopted the transverse engine layout which is typically found in economy cars (such as Peugeot and Citroën), since that would limit the type and power of engines that can be installed. To be able to mount powerful engines (such as a V8 engine in the Audi S4 and Audi RS4, as well as the W12 engine in the Audi A8L W12), Audi has usually engineered its more expensive cars with a longitudinally front-mounted engine, in an "overhung" position, over the front wheels in front of the axle line—this layout dates back to the DKW and Auto Union saloons from the 1950s. But while this allows for the easy adoption of all-wheel drive, it goes against the ideal 50:50 weight distribution.
In all its post Volkswagen era models, Audi has firmly refused to adopt the traditional rear-wheel drive layout favored by its two archrivals Mercedes-Benz and BMW, favoring either front-wheel drive or all-wheel drive. The majority of Audi's lineup in the United States features all-wheel drive standard on most of its expensive vehicles (only the entry-level trims of the A4 and A6 are available with front-wheel drive), in contrast to Mercedes-Benz and BMW whose lineup treats all-wheel drive as an option. BMW did not offer all-wheel drive on its V8-powered cars (as opposed to crossover SUVs) until the 2010 BMW 7 Series and 2011 BMW 5 Series, while the Audi A8 has had all-wheel drive available/standard since the 1990s. Regarding high-performance variants, Audi S and RS models have always had all-wheel drive, unlike their direct rivals from BMW M and Mercedes-AMG whose cars are rear-wheel drive only (although their performance crossover SUVs are all-wheel drive).
Audi has recently applied the quattro badge to models such as the A3 and TT which do not use the Torsen-based system as in prior years with a mechanical center differential, but with the Haldex Traction electro-mechanical clutch AWD system.
Prior to the introduction of the Audi 80 and Audi 50 in 1972 and 1974, respectively, Audi had led the development of the EA111 and EA827 inline-four engine families. These new power units underpinned the water-cooled revival of parent company Volkswagen (in the Polo, Golf, Passat and Scirocco), whilst the many derivatives and descendants of these two basic engine designs have appeared in every generation of VW Group vehicles right up to the present day.
In the 1980s, Audi, along with Volvo, was the champion of the inline-five cylinder, 2.1/2.2 L engine as a longer-lasting alternative to more traditional six-cylinder engines. This engine was used not only in production cars but also in their race cars. The 2.1 L inline five-cylinder engine was used as a base for the rally cars in the 1980s, providing well over 400 horsepower (300 kilowatts) after modification. Before 1990, there were engines produced with a displacement between 2.0 L and 2.3 L. This range of engine capacity allowed for both fuel economy and power.
For the ultra-luxury version of its Audi A8 fullsize luxury flagship sedan, the Audi A8L W12, Audi uses the Volkswagen Group W12 engine instead of the conventional V12 engine favored by rivals Mercedes-Benz and BMW. The W12 engine configuration (also known as a "WR12") is created by forming two imaginary narrow-angle 15° VR6 engines at an angle of 72°, and the narrow angle of each set of cylinders allows just two overhead camshafts to drive each pair of banks, so just four are needed in total. The advantage of the W12 engine is its compact packaging, allowing Audi to build a 12-cylinder sedan with all-wheel drive, whereas a conventional V12 engine could have only a rear-wheel drive configuration as it would have no space in the engine bay for a differential and other components required to power the front wheels. In fact, the 6.0 L W12 in the Audi A8L W12 is smaller in overall dimensions than the 4.2 L V8 that powers the Audi A8 4.2 variants.[64] The 2011 Audi A8 debuted a revised 6.3-litre version of the W12 (WR12) engine with 500 PS (370 kW; 490 hp).
New models of the A3, A4, A6 and A8 have been introduced, with the ageing 1.8-litre engine now having been replaced by new Fuel Stratified Injection (FSI) engines. Nearly every petroleum burning model in the range now incorporates this fuel-saving technology.
In 2003, Volkswagen introduced the Direct-Shift Gearbox (DSG), a type of dual-clutch transmission. It is a type of automatic transmission, drivable like a conventional torque converter automatic transmission. Based on the gearbox found in the Group B S1, the system includes dual electro-hydraulically controlled clutches instead of a torque converter. This is implemented in some VW Golfs, Audi A3, Audi A4 and TT models where DSG is called S-Tronic.
Beginning in 2005, Audi has implemented white LED technology as daytime running lights (DRL) in their products. The distinctive shape of the DRLs has become a trademark of sorts. LEDs were first introduced on the Audi A8 W12, the world's first production car to have LED DRLs,[65][66][67] and have since spread throughout the entire model range. The LEDs are present on some Audi billboards.
Since 2010, Audi has also offered the LED technology in low- and high-beam headlights.[68]

Starting with the 2003 Audi A8, Audi has used a centralised control interface for its on-board infotainment systems, called Multi Media Interface (MMI). It is essentially a rotating control knob and 'segment' buttons—designed to control all in-car entertainment devices (radio, CD changer, iPod, TV tuner), satellite navigation, heating and ventilation, and other car controls with a screen.
The availability of MMI has gradually filtered down the Audi lineup, and following its introduction on the third generation A3 in 2011, MMI is now available across the entire range. It has been generally well received, as it requires less menu-surfing with its segment buttons around a central knob, along with 'main function' direct access buttons—with shortcuts to the radio or phone functions. The colour screen is mounted on the upright dashboard, and on the A4 (new), A5, A6, A8, and Q7, the controls are mounted horizontally.
Audi has assisted with technology to produce synthetic diesel from water and carbon dioxide.[69][70][71] Audi calls the synthetic diesel E-diesel. It is also working on synthetic gasoline (which it calls E-gasoline).[72]
Audi uses scanning gloves for parts registration during assembly, and automatic robots to transfer cars from factory to rail cars.[73]
