Audi's S8 is its biggest, baddest and most luxurious sedan.
With a twin-turbo V8 borrowed from the RS 7 and RS 6 Avant, it's plenty fast and will sound great too.
The S8 is based on Audi's awesome flagship A8 sedan but adds more performance and aggressive styling.
It serves as Audi's answer to Mercedes-AMG's S63 and BMW's M760i xDrive.
The S8's 4.0-liter V8 makes 563 horsepower and 590 pound-feet of torque.
