The Audi S5 Sportback has a sports-tuned chassis. The S-design 18-inch cast aluminum wheels are shod with 245/40 tires. Wheels up to 20 inches are available as options. The black brake calipers are emblazoned with S5 emblems. Servotronic speed-sensitive steering is also standard, with dynamic steering optionally available. A strut brace provides the front section of the car with additional rigidity.
