Audi A6
Audi made a high-performance, 4.2-litre V8 engine (parts code prefix: 077, identification code: AEC) with a Bosch KE-Motronic ECU available as an option in the original European S4s, and made the decision to continue to do so with the S6, making a version of the 4.2 available as an optional upgrade over the 2.2-litre inline five-cylinder turbo. Unlike the five-cylinder turbocharged version, the V8-powered S6 was supplied with a four-speed automatic transmission as standard, but kept the quattro four wheel drive. A six-speed manual gearbox was also available as an option.

Transmission options initially included only a six speed manual gearbox. Shortly after launch, the LuK originated multitronic continuously variable transmission (CVT), with selectable six or seven speeds, became available on models equipped with the 2.0 TSI petrol and 2.0 TDI diesel engines. Distribution of the engine torque to the driven roadwheels is only via the front wheels, and there is not a four-wheel drive offering, which the Audi A4 used as an option in its 'trademark' quattro.
