ABT Sportsline is introducing an update for its power package developed for the 2014 Audi S8 facelift.

Back in May we found out from ABT they were able to bump output of the V8 4.0-liter twin-turbo engine by 120 HP (88 kW) & 130 Nm (96 lb-ft) to 640 HP (471 kW) & 780 Nm (575 lb-ft) and now they are back with a second output boost to 675 HP (496 kW) & 840 Nm (619 lb-ft).

While the stock S8 sprints to 62 mph (100 km/h) in 4.1 seconds, ABT's version does it 0.5s quicker. The engineers have also removed the S8's 155 mph (250 km/h) top speed limiter and now the high-performance full-size sedan is capable of hitting a maximum speed of 180 mph (290 km/h).

Aside from packing more punch, the 2014 Audi S8 facelift by ABT has been lowered by 25mm and features a custom muffler system. Lastly, the tuner is offering 20- and 21-inch alloy wheel sets with 275/35 R20 and 275/35 R21 tires, respectively.

The Audi S8 tuning kit developed by ABT is offered in Germany with a two-year / 100,000 km warranty.
