As if the standard Audi S8 facelift wasn’t already an absolute monster, the aftermarket specialists over at ABT Sportsline decided to take the high-performance sedan even further by developing an upgrade program. The highlight was on the V8 4.0-liter twin-turbo engine which now churns 640 PS and a maximum torque of 780 Nm so the S8 has gained no less than 120 PS and 130 Nm. Performance numbers have not been revealed by the tuner but they did say the top speed was bumped to an impressive 174 mph (280 km/h).
The Audi S8 by ABT has also received an electronic lowering module reducing the ride height by 25mm, along with various styles of 20- and 21-inch alloy wheels, as well as a quad exhaust system made from stainless steel.
