Audi S6, S7 and S8 to Bow at Frankfurt Auto Show With New 4.0L V8 Turbo

At this year’s Frankfurt Motor Show, Audi will unveil four new S performance models, all packing a version of the brand’s new turbocharged V8 engine. Displacing 4.0-liters, this V8 can deliver up to serious power with improved fuel economy over past S versions.

In the new S6 sedan and Avant models, the engine will produce 420-hp and 406 lb-ft of torque, enabling a 0-62 mph time of 4.8 seconds. The same engine, with the same output will also be found in the new S7, which will deliver a 4.9 second 0-62 mph time thanks to a slightly heavier chassis.

All models will come standard with Audi’s quattro technology, while the S6 and S7 will get Audi’s S-Tronic dual-clutch transmission. The S8 will come equipped with an 8-speed automatic.

Audi is also touting fuel economy improvements, due to a lighter chassis as well as a new ‘cylinder on demand’ technology that will reduce the number of active cylinders to four under lighter loads.
