The Audi RS7 Sportback is already one of the most powerful liftbacks with an internal combustion engine, but tuner ABT has presented two new versions called RS7 Legacy Edition and RS7-S.

The 4.0-liter twin-turbocharged V8 has been reworked, increasing its power from 621 hp. to 710 hp and torque increased from 850 Nm to 949 Nm. These improvements were achieved by the installation of the ABT engine control unit and stainless steel exhaust system with electronically controlled exhaust valves.

At the front, a new carbon fiber splitter has been fitted along with additional new black air intakes that are slightly larger than standard. These new air intakes are only available for the RS7 Legacy Edition.

The German tuner has developed new carbon side skirts for the car. The Legacy Edition model received carbon air intakes on the front side panels, a carbon air intake on the hood and a fixed carbon rear spoiler. The RS7-S is a little more refined and gives up the spoiler in favor of a small carbon lip. There are also no ventilation holes on the side panels.

ABT also created a new set of 22-inch forged wheels. Both the RS7 Legacy Edition and RS7-S feature height-adjustable springs and coils and new anti-roll bars that are 40% stiffer than standard. ABT installed a new shift knob cover, carbon fiber parts and new shifters.
