The suspension in the front and rear of the Audi RS 4 Avant is built on newly developed five-link supports. This axle concept enables optimum absorption of longitudinal and transverse forces.
With the standard RS sports suspension, the RS 4 Avant is seven millimeters lower than the S4 basic model with sports suspension. Alternatively, Audi Sport offers the RS sports suspension plus with Dynamic Ride Control (DRC). A new damper generation with an integrated switch valve ensures a clear spread between the individual modes of Audi drive select. Drivers can create their own personal driving experience using the dynamic handling system fitted as standard.
Audi drive select also influences the characteristics of the engine and the steering. What’s more, the system also adapts the characteristic curve for shifting, the exhaust door control, and other optional modules in the four modes: auto, comfort, dynamic and individual.
As an alternative to the redeveloped electromechanical power steering, Audi Sport also offers dynamic steering with RS-specific tuning. This uses a superposition gear to vary its ratio by up to 100 percent – depending on the car's speed and the mode selected in the Audi drive select dynamic handling system. For sporty driving in dynamic mode, the gear ratio of the dynamic steering remains constant at 14:1.
The RS 4 Avant (combined fuel consumption in l/100 km: 8.8 [26.7 US mpg]; combined CO2 emissions in g/km: 200–199 [321.9–320.3 g/mi]) is fitted with 19-inch aluminum forged alloy wheels as standard with 265/35 tires. Alternatively, 20-inch wheels are available as an option with different designs including a new, particularly lightweight fully milled wheel. These are fitted with 275/30 tires.
Behind these large wheels are powerful RS steel brakes with perforated composite disks. At the front axle, these have a diameter of 375 millimeters (14.8 in), while at the rear axle, they have a diameter of 330 millimeters (13.0 in). The six-piston brake calipers with the RS emblem are painted in black, or in red as an option. Upon request, Audi Sport will also equip the front axle with particularly durable and low-wear ceramic brakes with six-piston brake calipers and perforated discs measuring 400 millimeters (15.7 in) in diameter.
