Audi 100

The Audi 100 and Audi 200 (and sometimes called Audi 5000 in North America) are primarily mid-size/executive cars manufactured and marketed by the Audi division of the Volkswagen Group. The car was made from 1968 to 1997 across four generations (C1–C4), with a two-door model available in the first and second generation (C1-C2), and a five-door model available in the last three generations (C2–C4).

In 1982, the third generation Audi 100 achieved a remarkably low (for its time) drag coefficient of 0.30,^[1] featuring flush greenhouse sides with unique sliding window mountings.

The C2 and C3 models of the Audi 100 were marketed in North America as the Audi 5000 from 1978 to 1988, and in South Africa as the Audi 500.

In 1993, the models were mildly restyled, and renamed the Audi A6 series in conjunction with a general new Audi naming scheme, until they were replaced by a new generation of A6, internally code-named C5, in 1997. The Audi 100's traditional competitors include the Mercedes Benz E-Class and BMW 5-Series.

The first Audi 100, developed by Auto Union (Volkswagen's subsidiary) in Ingolstadt, was unveiled as a four-door sedan on November 26, 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 with similar details such as the louvres behind the rear side windows and the shape of the rear light clusters.

Audi followed 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 powered 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.
