The first official pictures of the Audi RS6 Avant have leaked to the web. See the images inside

The first official pictures of the Audi RS6 Avant have surfaced to the public prior to an official announcement.

Looking bold and aggressive, the wagon features a distinctive front fascia with LED headlights, matte aluminum accents and a honeycomb mesh grille with integrated "quattro" badging. Out back, there's a rear diffuser, a tailgate-mounted spoiler and a dual exhaust system with massive oval tips in typical RS style.

The premium styling carries over to the interior as it boasts high quality materials and a pleasing design. Once ensconced in the heavily-bolstered sport seats, drivers will find themselves surrounded by premium leather upholstery, carbon fiber trim and piano black accents. There's also a premium audio system and attractive alloy pedals.

Power will reportedly be provided by a twin-turbo 4.0-liter V8 engine that develops 560 HP (412 kW) and 700 Nm (516 lb-ft) of torque. Thanks to an eight-speed automatic transmission and quattro all-wheel drive, the RS6 could rocket from 0-100 km/h in 3.9 seconds and hit a top speed of 304 km/h (189 mph).

The RS6 Avant will likely be unveiled at the 2013 Geneva Motor Show, but the timing of the leak suggests a Detroit debut is also a possibility.
