Our spy photographers have snapped the first undisguised images of the 2012 Audi S6 Avant.

Caught near the company's Nürburgring testing facility, the prototype features aggressive bumpers, revised side skirts and a four-tailpipe exhaust system. Elsewhere, there's a sport-tuned suspension, high-performance brakes and massive alloy wheels.

Power will likely be provided by a 4.0-liter V8 with approxomitely 440 PS (324 kW / 434 hp), so you probably won't want to race an E63 AMG Estate anytime soon.
