About the Audi S6 C6
The C6-generation Audi S6 is defined by its 5.2-litre V10 engine, a unit sharing its basic architecture with the Lamborghini Gallardo but tuned for greater low-end torque. While visually discreet, it is distinguished by quad exhaust pipes and a signature strip of five LEDs in the front bumper, which pioneered the modern DRL trend. The driving experience is dominated by the smooth, linear power delivery of the naturally aspirated V10 and the security of the Torsen-based quattro system. Though heavier and less aggressive than the contemporary BMW M5, it remains a highly capable and unique high-speed cruiser.

Audi S6 C6 fun facts
- The S6's V10 engine was the first production application of a V10 in an Audi saloon, predating the C6 RS6 and the R8 V10.
- It was the first car to feature integrated LED daytime running lights in the front bumper, a design cue that soon became an industry standard.
- To fit the long V10 into the A6 engine bay, Audi moved the timing chains to the rear of the engine, requiring an engine-out service for chain maintenance.
