Audi S8 tuned to 640 hp by ABT Sportsline

Volkswagen Group tuning house ABT Sportsline debuted its latest version of Audi's flagship luxury-sport sedan, the Audi S8.

While Audi's changes to the exterior have been relatively mild, with restyled front and rear bumpers and a slightly redesigned grille, the tuning house once again focused on changes under the hood.
