These latest spy shots show an Audi S6 prototype on its way from a German port to Swedish Gothenburg.

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 aluminium mirror casings.

Under the hood, power will likely be provided by a turbocharged 4.0-litre V8 engine which will also be used in the Bentley Continental GT. It is reported that this engine is using a single turbo version in the Bentley and will produce 415 hp. However, this is no good for the S6 as it's less than the outgoing 5.2-litre V10 that develops 429 hp. Surely, Audi will engineer output to be higher. Exactly how much, we'll have to wait and see.
