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.

Alongside the 102mm carbon tailpipes, the super wagon also has a host of visual updates on the outside, such as the tweaked grille, bumpers, and rear diffuser. As a final touch, the Audi RS4 Avant rides on 21-inch wheels, shod in 275/25 rubber.

More carbon fiber was added inside too, where the part-leather seats can also be found, in addition to other upgrades.

ABT has baptized their latest project the RS4-R, and they will bring it at the Geneva Motor Show, probably alongside other tuned vehicles.
