Under the hood Audi will dispense of the V8 from the previous generation and replace it with a brand new supercharged 3.0-liter power unit, it offers significantly less fuel consumption than the outgoing engine while increasing overall power output to 350 ponies. The new lighter engine will be mated to the new dual-clutch S-Tronic transmission system (better known as VW's DSG) and we expect to see a sub 6-second 0-100km/h time while the top speed will be electronically limited to 250km/h. The same engine will also be used in the A6 facelift albeit slightly de-tuned to 290hp.

The excellent aggressive stance of the A4 meant the S4 only needed a few subtle enhancements, the most notable exterior features are the quad exhaust pipes and LED rear lights. Close inspection of front fascia also reveals a slightly redesigned grille, bumper and air intakes.

Both the sedan and Avant variants of the Audi S4 will make their world debuts at the Paris Motor Show in September.
