Next-generation flagship S-line model showing a front fascia with a new air intake design.

Here is the 2012 Audi S8 spied without any camouflage.

We get to see that front face for the first time here, as this Audi S8 prototype conducts testing while pulling a trailer in the European Alps.

That front fascia features new air intakes similar to the current A5 and upcoming A4 facelift.

At the back is a quad exhaust indicative of this flagship S-line model.

The Audi S8 will come with a Bentley-sourced 4.0-liter twin-turbo V8 that produces around 500 PS (368 kW / 493 bhp). Standard will be an eight-speed automatic gearbox and the Quattro all-wheel-drive system.
