By utilizing the sophisticated ABT Engine Control unit (AEC) the output of the 4.0-liter V8 increases from 591 HP / 590 lb-ft of torque to approximately 690 HP and 649 lb-ft (with 93 octane fuel) in a safe and reliable way. The ABT Performance Upgrade comes with TÜV (German DOT) certification and a lot of engine protection measures to provide drivers with a with guilt-free driving pleasure.

Whether used in combination with an ABT power upgrade or the regular engine performance, the ABT stainless steel exhaust system stirs the emotions even further. Consisting of a middle muffler replacement pipe, rear muffler with electronically adjustable exhaust valves and dual exhaust pipes per side the ABT exhaust system displays an impressive sound range. The ABT exhaust system significantly reduces exhaust back pressure and changes the look of the car by adding two 4-inch (102-mm) diameter matt carbon fiber end pipes to each side.

The sporty design of the RS 6 Avant is further highlighted by ABT 22” wheels. Drivers can choose between the lightweight ABT High Performance HR flowforming wheels in dark smoke or the elegant GR alloy wheels in either glossy black or matt black finish.

The ABT treatment for the Audi RS 6 Avant also includes high-quality carbon fiber upgrades for the interior: carbon fiber coated seat covers and dashboard side panels as well as a carbon fiber shift knob cover (the latter is also available directly through Audi of America Parts and Accessories).

And if that is not enough there still is the ABT RS6-R Edition – a spectacular tuning package that is as legendary as the RS 6 Avant itself and limited to just 125 units worldwide.
