The Audi intelligent mixed construction concept makes the car bodies of the new S4 models* very torsionally stiff and safe. Hot-formed parts form the high-strength, crash-safe backbone of the passenger cell. In comparison to the previous model the bodies are 15 kilograms (33.1 lb) and therefore form the basis for the low unladen weight of the new S4* and S4 Avant*. The Sedan weighs 1,630 kg (3,593.5 lb) with the standard quattro drive, while the Avant weighs 1,675 kg (3,692.7 lb) – each is 75 kg (165.3 lb) less than the weight of the previous models.
Another of the body’s strengths is aerodynamics. With a cd figure of 0.31, the new Audi S4 Avant offers the best figure in its competitive field. The drag coefficient of the S4 Sedan is a low 0.29. These top results come from refined design of the exterior skin and covering of large areas of the underbody which minimizes lift.
