Abt sportsline company offers new tuning package for the Audi RS4 last generation with some external and inner upgrades. There could be installed special 2.5cm extenders and 20 inch alloy firm abt wheels with sport tyres 265/30 ZR20 from German company Continetal.
Another difference is Abt logos on the sportcar body that indicates the tuning author. Bumpers and side skirt were not touched as they don't need to be improved. There are no upgrades for the engine too. Naturally aspirated motors have a little ability for chip tuning. But exhaust system has been changed to the original stainless from Abt. It allows the engine to sound a little bit better. Also Abt tuning package removes max speed limiter, or raises it to 290 km per hour.
The most obvious difference is the larger wheels
Because of no changes in car interior the company didn't decide to install any firm logos into steering wheel or gear box manipulator. The Audi RS4 B8 tuning from Abt sportsline didn't change the RS4 tech specs except its max speed that could be removed in other ways, but bigger wheels and upgraded exhaust system make sportcar more harmonious. The tuning RS4 price and sales start are unknown, more information in early 2013.
