ABT Sportsline is already offering certain conversion packages for the Audi S4 and RS4, but their latest work revolves around the regular A4 models, of the B9 generation. With their own engine control units, the tuner can lift the output of the four- and six-cylinder petrol and diesel engines, claiming as much as 325 PS and 660 Nm of torque when it comes to the 3.0-liter TDI.

That’s a 53 PS and 50 Nm of torque increase over the stock car, while the ECU tune includes more power for the lesser version, too, 250 PS and 450 Nm of torque, up from the standard 218 PS and 400 Nm  of torque.


The 2.0-liter TDI with 190 PS and 400 Nm of torque is now making 215 PS and 440 Nm of torque, and the 2.0-liter TSI petrol unit gets boosted to 330 PS and 440 Nm of torque, up from 252 PS and 370 Nm  of torque.

For the right sum, ABT will throw in new suspension springs and a few aftermarket parts for the exterior too, such as add-ons for the grille, front and rear bumpers, and fender inserts. Joining them are the new tailpipes and one of four rim choices available in different sizes and finishes, including the 20-inch ones equipping the Audi A4 Avant pictured below.

Greeting users inside are the integrated entrance lights, push-button start cover and the carbon fiber gearstick.
