First generation (C4) S6 (1995-1997)

The Audi S6 is a high performance variant of the A6. It went on sale in 1994 shortly after the A6 was introduced, replacing the Audi 100. The original S6 was largely the same as the out going version - first generation S4, with the only visible differences being new body cladding and badging.

Audi S6 Manual

Audi was constantly re-structuring their model lineup in early and mid-1990s and in 1995 began selling the fifth generation 100 model as the A6. Wanting to keep a sports-saloon in their lineup, the company made small revisions to what had been badged as the S4 and began reselling it as the S6; the S4 would eventually become a completely separate car based on Audi's smaller A4.

For 1995, the S6 was powered by a 2.2 L turbocharged five-cylinder engine producing 230 PS (169 kW/227 hp) @ 5900 rpm and 350 Nm (258 ft.lb) @ around 1950 rpm. The powerful engine gave the S6 surprisingly good performance, it had a top speed of 151 mph and went from 0 to 62 mph in 6.1 seconds; 100 mph was reached in 17.5 seconds.

The vehicle came standard with a six speed manual gearbox (five speed only in the USA), and Audi's quattro all-wheel-drive system. It was available as both a saloon and an "Avant" to European and United States customers, but only as a saloon in Canada, Asia and Australia.

Audi had made a high-performance, 4.2 L V8 available as an option in the first generation European S4s, and made the decision to continue to do so with the S6, making a 290 PS (213¬ kW/286 hp) version of the 4.2 available as an optional upgrade over the 5-cylinder. Unlike the turbocharged version, the V8-powered S6 was shipped with automatic transmission by default, but kept the quattro four wheel drive. A 6-speed manual gearbox was available as an option.

An even more powerful and very limited-production S6 Plus, powered by another version of the 32 valve 4.2 litre V8 (engine code AHK, later to be seen in the Audi S8, as AKH), was briefly available to European customers. Developed by quattro GmbH (a wholly owned subsidiary of Audi AG), it was available for sale only during the 1997 model year (production from 04/96-07/97). Only 952 cars were produced in total - 855 Avant (Estate) and 97 saloons.

Audi's performance division reworked key parts of the engine and increased the power output to 326 PS (240 kW/322 hp). During this process they also made revisions to the suspension, brakes and transmission. With so much power on tap, the S6 Plus could reach 62 mph from a standstill in 5.6(saloon) and 5.7(avant) seconds, making it comparable in terms of acceleration to vehicles like the Porsche 944 Turbo.
