The first Audi 100, developed by Volkswagen's subsidiary Auto Union at Ingolstadt, was shown to the press as a four-door sedan on 26 November 1968. Its name originally denoting a power output of 100 PS (74 kW), the Audi 100 was the company's largest car since the revival of the Audi brand by Volkswagen in 1965. The C1 platform spawned several variants: the Audi 100 two- and four-door saloons, and the Audi 100 Coupé S, a fastback coupé, which bore a resemblance to the Aston Martin DBS released a year earlier, especially at the rear end, including details such as the louvres behind the rear side windows and the shape of the rear light clusters.
Audi followed up the introduction of the four-door saloon in November 1968 with a two-door saloon in October 1969 and the 100 Coupé S in autumn 1970. The cars' 1.8 litre four-cylinder engines originally came in base 100 (80 PS or 59 kW or 79 hp), 100 S (90 PS or 66 kW or 89 hp), and 100 LS (100 PS or 74 kW or 99 hp) versions, while the Coupé was driven by a bored-out 1.9 litre developing 115 PS (85 kW; 113 hp). From April 1970 the 100 LS could be ordered with a three-speed automatic transmission sourced from Volkswagen.
The Audi 100 included a rough engine note that was described as unlikely to discourage buyers whose first car had been a Volkswagen and who aspired to drive a diesel powered (pre-turbo) Mercedes-Benz. The Ingolstadt production line was at full capacity, but supply fell short of demand that during the summer of 1970 an additional production line for Audi 100s was set up in Volkswagen's own Wolfsburg plant, which made it the first water-cooled car to be produced in Germany's (and by some criteria the world's) largest car plant.
Starting with the 1972 model year, the 80 and 90 PS versions were replaced by a new regular-petrol-variant of the 1.8 litre engine developing 85 PS (84 hp/63 kW); at the same time, the 100 GL was introduced featuring the 1.9 liter engine formerly used only in the Coupé S.
In March 1971 the 500,000th Audi was produced. By now the Audi 100 had become the most commercially successful model in the company's history.
In September 1973 (for the 1974 model year) the 100 received a minor facelift with a somewhat smaller squared-off grille, with correspondingly more angular front fenders, and with reshuffled taillight lens patterns. The rear torsion bar was replaced by coil springs. For model year 1975 the base 100 was re-christened the 100 L and received a 1.6 litre four-cylinder engine (coming out of the Audi 80). A four-wheel drive prototype of the Audi 100 C1 was built in 1976, long before the appearance of the quattro.
In the United States the Audi 100 appeared in 1970 in LS guise, with a 115 hp (86 kW) SAE 1.8 liter engine and with either two or four doors. For 1972 the engine was enlarged to 1.9 litres, but the SAE net claimed power was down to 91 hp (68 kW). A base and a GL model were added, as was an automatic transmission. For 1974 the lineup was again restricted to the 100 LS, while the larger safety bumpers were now fitted. Power increased to 95 hp (71 kW) for 1975, by changing to fuel injection. Standard equipment was improved accompanied by an increase in prices. In August 1977 the new Audi 5000 replaced the 100, although another 537 leftover cars were sold in 1978. The Coupé was not available in the United States.

The restyled C2 Audi 100 was launched in 1976, with an in-line five-cylinder engine. It was initially a 100 PS (74 kW) engine offering "six-cylinder power and four-cylinder economy", and later upgraded to 136 PS (100 kW).
The Coupé was discontinued, but a five-door hatchback model, the 100 Avant, was launched in August 1977 as part of this generation. The mainstay of the range remained the four-door sedan model. A two-door sedan version was offered, primarily on the domestic market, from February 1977, but by now there was little demand for large two-door sedans, thus a few of these two-door Audi 100 C2s were sold.
At the end of September 1977, the Audi 100 became the manufacturer's first model to reach a production level of 1,000,000 units. The millionth Audi 100 was a hatchback Audi 100 Avant assembled not at the company's main Ingolstadt plant but to the west, at the Neckarsulm factory which, since the demise of the mainstream volume models from the NSU range, had been concentrating on providing additional production capacity for the fast selling Audi range.

The RHD Audi 200 5E and 5T were introduced into the UK in 1979, only 500 were imported. The 5T (170 PS) was a higher spec Turbo version of the 5E (136 PS injection) and came with many optional extras as standard. The UK version of the 5T had opening quarter lights, electric wing mirrors, a sun roof, cruise control and heated seats. All Type 43 200's came with automatic gearboxes, with a five-speed manual available by special order.
Audi 5000 (1978-1983)
In North America, where 133,512 of the Audi 5000 C2 were sold, only five-cylinder engines were available. The diesel was originally not available in California, as Porsche-Audi of North America were unable to meet that state's strict emissions standards. The naturally aspirated diesel was also only available with a five-speed manual, a handicap in the American market. It wasn't until the 1983 introduction of the turbodiesel that these issues were rectified. The 5000 had twin round headlamps for the first two model years, after which they were replaced by rectangular units.
In 1980 the 5000 Turbo arrived in the US. This model only delivered 130 hp (97 kW), more than twenty percent less than the European spec model. Aside from meeting the strict US emissions, this model also had lower boost pressure to be able to run on the lower octane unleaded fuel available in America. While the Turbo also received a harder, sportier suspension, bigger aluminium wheels, and other performance upgrades, it was also only available with a three-speed automatic transmission. Road & Track were able to reach a top speed of 113 mph (182 km/h) in the federalized car, slower than a naturally aspirated European market 2.1 E. In the US, reflecting the Audi's luxury connotations, 90 percent of 5000s received the costly "S" equipment package.

The Audi 100 had an aerodynamic look, achieving a drag coefficient of 0.30 for its smoothest base model. The increased aerodynamic efficiency resulted in better fuel economy. The design was in contrast from the boxy shape of the C2. Audi innovated flush windows on the C3, a key area for aerodynamic drag that has been adopted by virtually all manufacturers today. The aerodynamic body gave the 100 higher top speed than other cars of similar engine size. A new technology introduced in the C3 included the procon-ten safety system.
The two-door models were no longer available, and the Audi 100 Avant was reintroduced as Audi's first attempt at a station wagon based on the 100. The 200, launched in 1983 continued as the upmarket variant with several versions of the 2.2 L turbo 5-cylinder available in different markets over its life ranging in power outputs from 165 PS (121 kW) MC engine, through the 200 PS (147 kW) versions to the final 220 PS (162 kW) 20-valve 3B engine available from 1991. The 1983 Audi 200 Turbo had a top speed of 139 mph (224 km/h). The MC turbo engine was available in the 100 as well for some markets.
The 1991 200 20V was distinguished by its flared front and rounded rear wheel arches instead of the flat type used for the rest of the 100-200 range, this allowed wider wheel and tire combinations to be fitted to 20V models. U.S. magazine articles of the period reported 0-60 times of the 20v Audi 200 under 7 seconds, with 1/4 mile times in the mid to upper 15 second mark.
The 100 also featured a 2.5 L straight-five direct injection turbo-diesel (TDI) model with 120 PS (88 kW) introduced in January 1990 (engine code 1T). A such-engined Audi 100 was the first model to wear the TDI label. It had a brief career in the C3, being replaced in December of that year when the C4 arrived.
Reported sudden unintended acceleration
During model years 1983–1987, Audi's U.S. sales fell after a series of recalls of Audi 5000 models associated with reported incidents of sudden unintended acceleration linked to six deaths and 700 accidents. At the time, National Highway Traffic Safety Administration (NHTSA) was investigating 50 car models from 20 manufacturers for sudden surges of power.
In North America, the CBS television broadcast network 60 Minutes news program aired a report titled Out of Control on November 23, 1986. It featured interviews with six people who had sued Audi after reporting unintended acceleration, including footage of an Audi 5000 ostensibly displaying a surge of acceleration while the brake pedal was depressed. Subsequent investigation revealed that 60 Minutes had not disclosed they had engineered the vehicle's behavior – fitting a canister of compressed air on the passenger-side floor, to pump fluid via a hose to a hole drilled into the transmission — the arrangement executed by one of the experts who had testified on behalf of a plaintiff in a then-pending lawsuit against Audi's parent company.
Audi initially responded by suggesting that the drivers of the cars involved in the incidents were at fault, because they had stepped on the accelerator pedal rather than the brake. 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 mainly by factors such as confusion of pedals. CBS acknowledged the report and stressed its findings that “the problem could be aggravated by vehicle design, the shape, location and feel of gas and brake pedals." Audi's research demonstrated that many of the drivers who encountered "unintended acceleration" were "below average in height", indicating their knowledge of a relationship between design and the incidents.
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."
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. 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."
With the series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. 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. It is unclear what was done regarding the defects in the idle-stabilization system. Subsequent to the recall campaigns, vehicles now include gear shift patterns and brake interlock mechanisms to prevent inadvertent gear selection.
Audi's U.S. sales, which had reached 74,061 in 1985, dropped to 12,283 in 1991 and remained level for three years. – with resale values falling dramatically. Audi subsequently offered increased warranty protection and renamed the affected models — with the 5000 becoming the 100 and 200 in 1989. The company only reached the same level of U.S. sales again by model year 2000.
As of early 2010, a class-action lawsuit — dealing with a charge that on account of the sudden acceleration controversy, Audi models had lost resale value — filed in 1987 by about 7,500 Audi Audi 5000-model owners remains unsettled and is currently contested in county court in Chicago after appeals at the Illinois state and U.S. federal levels. The NHTSA's findings have been "small solace for Audi in defense of product liability actions, as more and more successful cases used Audi's human factor design errors and failure to warn or recall as a basis for liability."

In 1988, Audi entered the Trans-Am Series with the 200 turbo quattro by contracting Bob Tullius Group 44 Racing. The car was equipped with the Quattro system. The car was piloted by Haywood and with both Walter Röhrl and Hans Joachim Stuck won eight out of thirteen events. Audi moved to IMSA by the end of the season, the SCCA would change the regulation to a two-wheel drive only and banning cars with non-American engines. The Historic Trans-am & IMSA Group is dedicated to the preservation of the cars that ran in the SCCA Trans-am series and the similar IMSA GTO class from 1980 until 1991.
Audi also used the 200 Turbo Quattro 20v as their Group A rally car replacement for the aging Audi Quattro after the FIA eliminating Group B in 1986. The 1987 Group A 200 was piloted by former World Rally Champion drivers Hannu Mikkola and Walter Rohl. The Audi 200 became the first four-wheel-drive car to win the East Africa Safari Rally with Hannu Mikkola in the pilot seat. The 200 Quattro become the last car Audi campaigned in racing.

Audi released the C4 (a heavily revised C3) in late 1990 in Europe and 1991 in other markets. The C3-platform Audi V8 continued to be sold as a separate line. The major change for the C4 was the introduction of a 2.8 L, 90-degree, SOHC 12v, V6 engine. It was later joined by a 2.6 L variant, of the same configuration as the 2.8 L unit. They are essentially the same engines offered in the 1992, B4 Audi 80. The option of quattro permanent four-wheel drive was an option across the range, and the Audi 100 quattro was available with a ZF four-speed automatic gearbox.
For the 1995 model year, in conjunction with some styling revisions, Audi dropped the Audi 100 tag, renaming it the A6 instead. In addition, the existing 100-derived Audi S4 became the S6. The S4 name was later re-used for the high-performance derivative of the Audi A4. The Audi V8 had been replaced by the A8 in 1994.
The C4-based A6 continued until early 1997, when it was replaced by an all-new A6.
In addition to the C platform codes, Audi assigned type numbers to their models:
- F104: C1; Audi 100 (1968–1976)
- Type 43: C2; Audi 100 (1976–1982); Audi 200 (1979–1982)
- Type 44: C3; Audi 100 (1983–1991); Audi 200 (1983–1992)
- Type 4A: C4; Audi 100 (1990–1994); Audi S4 (1992–1994); Audi A6 (1994–1997); Audi S6 (1994–1997)
The C3-platform Audi 100 was also produced in Changchun, China, by FAW (First Automobile Works, a Chinese automotive manufacturer) during the 1990s. Since most products in China are designed for government use, all 100s manufactured as FAWs were front-wheel drive sedans with a 2.0 L inline-4 motor or a 2.3 L inline-5 motor.
In 1990, Politburo of the CCP approved a resolution to circumscribe car import and the engine displacement of cars equipped to officials. Furthermore, the resolution also prescribed that all cars of central departments of both Party and government must be domestic built. As the most luxurious and advanced cars made in China in early-1990s, FAW-Audi 100 and 200 had a high percentage of the Chinese high-class market of executive cars for nearly one decade, until the C3-platform cars was replaced by Audi A6 in 1999.
During the negotiation between FAW and Volkswagen in late-1980s, Volkswagen acceded to FAW's suggestion of combining the C3 platform with previously introduced Chrysler engines in the new generation Hongqi (Red Flag). Hongqi CA7200 series with the technology of C3 were launched in mid-1990s, while most of C3 Audi 100 parts could be made in China. CA7200 were initially equipped with Chrysler 2.0 L or 2.2 L 4-cylinder 488 engines, whose product line was introduced into China in 1987. In 2000s (decade), new Nissan VQ20 engines replaced the original 4-cylinder petrol engine.
At the Geneva Motor Show in March 1990 Audi presented its first iteration of the Audi Duo (or Audi 100 Avant Duo) experimental vehicle, a plug-in parallel hybrid based on the Audi 100 Avant quattro. This car had a 12.6 bhp (9.4 kW) Siemens electric motor which drove the rear wheels. A trunk-mounted nickel-cadmium battery supplied energy to the motor that drove the rear wheels. The vehicle's front wheels were powered by a 2.3-litre five-cylinder engine with an output of 136 PS (100 kW; 134 hp). The intent was to produce a vehicle which could operate on the engine in the country and electric mode in the city. Mode of operation could be selected by the driver. Ten vehicles are believed to have been made; one drawback was the extra weight of the electric drive, making vehicles less efficient when running on their engines alone than standard Audi 100s with the same engine.
In late 1991, Audi unveiled the second Duo generation – likewise based on the Audi 100 Avant quattro. Once again this featured an electric motor, a 28.6 PS (21 kW; 28 hp) three-phase machine, driving the rear wheels. This time, however, the rear wheels were additionally powered via the Torsen differential from the main engine compartment, which housed a 2.0-litre four-cylinder engine.
