The engine also guarantees extremely sporty acceleration data. The acceleration from zero to 100 km/h depends on the respective vehicle but all models have one thing in common: Acceleration is always incredible. The Abt Audi AS4 only takes 5.2 seconds for the sprint, the AS6-R 5.7 seconds and the larger Abt VW Touareg VS8-R and AS8-R 5.9 seconds. The same goes for the top speed data: The Touareg reaches 260 km/h and the AS-models even race to 280 or 290 km/h. With Abt Sportsline, an increase in power and durability are no opposites and do not exclude each other. The modified motor management guarantees performance throughout the car’s life. The Bavarian tuning company always carries out extensive tests under real conditions in terms of the capacity of new technical developments. The Abt engineers determine the greatest possible power increase without reducing the life expectancy of the original engine on the engine test bench and on the road. Besides a new intake manifold also a new injection system was developed for the supercharger thus ensuring best possible combustion. However, the real power booster is the supercharger. The charger flanged to the intake manifold is operated by means of screw-type compressor technology.  Two turning rotors with different angular speeds pressurize the air by 0.45 bar. The advantages of this technology are engine smoothness, durability and consistent power development – in other words just right for the sporty eight-cylinder vehicles of Abt Sportsline.
