As if their previous Audi S8 tune with 640PS (632hp) wasn’t fast enough, ABT has found a way to fork a few more dozen ponies out of the 4.0-liter twin-turbo V8.

In stock trim, the force-fed V8 is rated at 520PS (513hp) and 650Nm (479 lb-ft), but with ABT’s new engine software and muffler system, output is boosted to 675PS (666hp) and 840Nm (619 lb-ft).

With these upgrades, the S8 powers up to 100km/h (62mph) in just 3.9 seconds and can continue to accelerate up until 290km/h (180mph), compared to the standard model’s 4.1 seconds and 250km/h (155mph) limited top speed.

If you want to show off your ABT tune, the Germans can hook you up with some of their discreet badges, different exhaust finishers, and 20- or 21-inch alloy wheels in gun metal, silver or black shades.
