The newest generation of Audis S- and RS- models have pretty much said goodbye to the tried-and-true 4.2-liter naturally aspirated V-8 engine that powered them in the past for so long. Now, most are packing a mighty 4.0-liter, twin-turbocharged V-8 thats packed with potential. One of those cars is the Audi S6 and its a monster right off of the factory floor. The German aftermarket car tuning team at ABT Sportsline that specialize in cars from the Volkswagen Automotive Group knew they had a car that they could get some serious power from, so they designed a full upgrade program for the Audi S6. Called the AS6-R, the new upgrade program features a full engine tuning upgrade for the new V-8, a revised suspension, new 3 piece wheels that reduce weight, and a number of exterior upgrades that add a touch of visual muscle to the German sports car.
The 4.0-liter V-8 engine uses a pair of turbochargers to create a generous amount of boost pressure throughout the rev range for the engine. This gives the engine a great deal of potential that the team at ABT Sportsline was able to tap into with their long history of tuning expertise with Audis. The team designed and installed a pair of bigger turbochargers that can supply the engine with even greater amounts of boost pressure than before to create more power. A full stainless steel exhaust system with quad tips and bigger diameter helps optimize backpressure for quicker spool time. The team then installed a custom software tune for the ECU so that a total of 600 horsepower and 553 lb-ft. of torque is sent to all four of the 3 piece wheels through the Quattro all-wheel drive system. This enables the sports car to accelerate to 62 mph in just 3.9 seconds.
The added power required the German team to modify the chassis and suspension. The team at ABT Sportsline opted for a set of custom tailored sport springs that lower the overall ride height by 25 mm for a better center of gravity and improved handling. The team then installed a set of 3 piece wheels made from forged aluminum that reduce weight and increase the cars footprint.
The final aspect that was modified was the exterior. Here, they fitted a new front bumper spoiler and radiator grille. Above each of the 3 piece wheels sits a new fender insert up front while side skirts run towards the rear. A new rear apron set and spoiler help give the back end a more aggressive stance.
