On the test bench: The Audi S6 C7

CPA PowerBox achieves extra power

The A6 is considered the mediocrity of all things and the flagship of the Ingolstadt-based company. As an S6, the V8 biturbo, which is also used in the RS6, delivers an impressive 450 hp. Since the engine offers enormous performance potential in our eyes, the power could be increased to up to 507 hp by means of specially developed software. The torque has also been increased from 550 NM to up to 670NM. It was important to us to maintain the suitability for everyday use and the durability of the components despite this massive increase in performance. Thanks to the CPA Connective system, they have the different performance levels in their hands at any time.
