The new generation Audi RS4 Avant has fallen into the hands of ABT Sportsline once more, only to come out even hotter than before. By fitting the 2.9-liter twin-turbo V6 engine with an engine control unit, and a high-performance exhaust system, the tuner’s engineers were able to lift the output to 530PS (523hp) and 690Nm (509lb-ft) of torque.

This represents a 20PS (20hp) and 10Nm (7lb-ft) of torque increase over their previous RS4 project, and 80PS (79hp) and 90Nm (66lb-ft) of torque more than the stock car. Cornering performance is said to be enhanced by the sport stabilizers and height adjustable suspension springs. Those looking for a bit more will have to wait for the ‘shock absorber setup’, which is currently in development with KW.
