We’ve recently heard about another tuning program for the facelifted Audi S4, this time from the German aftermarket specialists ABT Sportsline. They’ve added a few in-house tweaks and gadgets, related to both looks and performance, and simply named this upgrade package the AS4.
The original output of the S4 is a somewhat intriguingly low 328 HP and thus has needed a bit of raise. ABT have added a new sports exhaust system which added 101 HP to the output, the car now delivering no less than 429 HP and a maximum torque amplified from 440 Nm (328 lb-ft) to 520 (383 lb-ft). The changes made to the 3.0-liter supercharged V6 allow the car to reach a maximum speed of 282 km/h (175 mph).
In terms of looks, the vehicle has been done a few finishing touches, but quite moderate, like front fender air vents. In addition, ABT will equip the car, at customer’s choice, with 19- or 20- inch alloy wheels encased in high performance tires.
