ABT Power accelerates Audi S8 at 100 km/h in 3,6 Secs. Incredibly fast but providing first-class comfort: the Audi S8 tuned by ABT Sportsline is proof of the fact that you can in fact build a super sports car that is not uncomfortable, noisy and cramped. A luxury limo at its core, this car accelerates as fast as a Ferrari or Lamborghini. “As always, we have timed it precisely: our S8 reaches 100 kph in 3.6 seconds. And in contrast to the serial version, its top speed is 290 kph,” says a proud CEO Hans-Jürgen Abt. To realise this impressive performance, the globally largest tuner of cars produced by the Volkswagen Group has uprated the car from 520 hp / 382 kW to 675 hp / 496 kW and from 650 to 840 Nm.
