The Audi S6 was initially introduced to the North American market in 1994 as a sedan and “Avant” wagon. The S6 remains the high-performance analogue to the relatively mild-mannered A6 executive sedan, offering excellent straight line performance as well as remarkable handling and braking capabilities. The S6 continues to set the standard for fast, yet luxurious vehicles that offer excellent overall performance.



The current model features a 4.0-liter twin-turbocharged DOHC eight-cylinder engine. Fitted with Turbo Fuel Stratified Injection and stop-start technology for increased fuel efficiency, the 4.0-liter produces 420 horsepower and 405 pound-feet of torque. Not only does the Audi S6 share this engine with the current Audi A8 luxury sedan, it can also be found under the hood of its high-performance stable mate, the Audi S8. The 4.0-liter engine in the S8 offers a higher state of tune for a total power output of 520 horsepower.

The previous generation Audi S6 featured a 5.2-liter ten-cylinder engine, codenamed BXA. This engine is closely related to the 5.0-liter ten-cylinder engine found in the Lamborghini Gallardo, except the BXA engine features a longer stroke and a wider bore for increased torque at lower revs. Fitted with Fuel Stratified Injection, the 5.2-liter engine produces 429 horsepower and 398 pound-feet of torque.

From 1999 to 2003, Audi used its 4.2-liter DOHC eight-cylinder engine. Codenamed AQJ and ANK, it featured a magnesium two-stage variable intake manifold, sequential fuel injection and five valves per cylinder. Power output was rated at 335 horsepower and 310 pound-feet of torque.

Salvage yards, dismantlers and engine brokers dealing in motors for higher-end vehicles like the Audi S6 are more than likely to have this engine in stock. With the relative complexity of these motors, any engine replacement should be left in the hands of a skilled technician who is familiar with modern Audis.
