Our spies have managed to catch an Audi S6 prototype undergoing testing in Germany.
Looking tastefully restrained, the S6 is distinguished by sportier fascias, aerodynamic side skirts, and a four-tailpipe exhaust system. Additionally, we can expect the production model to feature a revised grille and faux aluminum mirror casings.
Under the hood, power will likely be provided by a turbocharged 4.0-liter V8 engine which will also be used in the Bentley Continental GT. It is reported that this engine using a single turbo version in the Bentley will produce 415 hp (309 kW / 420 PS). However, this is no good for the S6 as it's less than the outgoing 5.2-liter V10 that develops 429 hp (320 kW / 435 PS). Surely, Audi will engineer output to be higher. Exactly how much, we'll have to wait and see.
