Audi tuning specialist ABT Sportsline has released the first images of its new performance kit for the A7 sportback, which it plans to unveil at next month’s 2011 Geneva Motor Show alongside a range of other modified Volkswagen Group cars.

ABT has taken an uncharacteristically subtle approach for its latest kit for the A7, with most of the exterior elements consisting of new bumpers, sporty side sills and new rear diffuser with squared-off exhaust tips. The car also sports new wheels, available in sizes ranging from 19 to 21 inches in diameter.

Inside, the ABT prepped A7 gets a custom steering wheel with a Nappa leather rim, carbon-look leather accents, aluminum pedals and a special gear shift to finish off the package.

ABT offers a range of power-up mods for the differing A7 models, so it’s unclear what package will be displayed in Geneva. For the base 3.0-liter V-6 TDI, ABT offers two kits developing 282 and 310 horsepower, respectively, while the 3.0 V-6 TSI kit delivers up to 410 horsepower.

Also on show will be a heavily modified Audi R8 complete with a supercharger kit (pictured below).
