UPDATE: Thanks to our "sharp as tacks" WCF members for giving us a swift kick in the #@!% for misidentifying these images. It is indeed an RS4.

Our spies have already snapped pictures of the 2013 Audi RS6 Avant, but here are the first patent photos of the upcoming model.

As you can see, the wagon is equipped with an aggressive body kit that includes a new front fascia, aerodynamic side skirts and a revised rear bumper with an integrated diffuser. There's also a mesh grille, a tailgate-mounted spoiler and two massive exhaust tips.

Engine specifications remain unconfirmed, but rumors suggest the model will have a twin-turbo 4.0-liter V8 with up to 580 PS (427 kW / 572 hp). It will likely be connected to a dual-clutch transmission which sends power to the ground via a sport-tuned quattro all-wheel drive system.

The Audi RS6 Avant could be unveiled later this year, so look for a possible debut at the Paris Motor Show.
