Avus Performance makes their own version of the Audi S4 and gives the ride a sport limo attitude.
The Avus Audi S4 comes with a black trim for exterior elements like the front grille, mirror caps, rear diffuser and bumper blades in front. The suspension makes use of threaded springs that allows a more precise individual adjustment of the height without affecting the Magnetic Ride feature of the Audi. Avus fits the ride with 20 inch rims mated with S1 Evo tires by Hankook Ventus.
The insides of the car get custom leather treatment with its steering wheel getting some carbon fiber elements.
The engine was also optimized to give out 430 PS compared to the 333 PS of the standard. Avus also reworked the exhaust system of the car using stainless steel.
