A 120-hp increase should give potent sedan lightning acceleration.
Stylish, spacious and with performance to burn, the Audi S8 is the complete package yet ABT Sportsline just couldn't resist stamping its mark on the luxury sedan. The Audi's 4.0-liter twin-turbo V8 was the first area to receive attention. Without revealing what mods it made, ABT claims output has increased by 120 hp and 96 lb-ft of torque to 640 hp and 575 lb-ft. The result is a new top speed of 174 mph. Other upgrades include a stainless-steel quad exhaust, a 25-mm electronic lowering module and a selection of 20- and 21-inch alloys.
