A revised five-link construction is used on the front axle. At the rear, a five-link suspension replaces the trapezoidal-link suspension used on the previous model. This benefits the sporty driving characteristics and agility. It also improves comfort significantly. With the standard RS sport suspension, the new RS5 Coupe sits 7 millimeters (0.3 in) lower than the base model. As an alternative, Audi Sport also offers the RS sport suspension plus with Dynamic Ride Control (DRC), ceramic brakes and dynamic steering with RS-specific tuning. Drivers can make their personal driving experience more individual, dynamic or comfortable using the standard dynamic handling system Audi drive select.
The chain drive uses a new concept to reduce the drive power required: the crankshaft drives the balancer shaft via gears, with the shaft lying far down in the V of the cylinder banks. From here chains run to the four camshaft sprockets. These are trioval in shape, i.e. they have a slightly triangular shape, in order to compensate for peak forces. The balancer shaft rotates on roller bearings with particularly low levels of friction.
Drivers can create their own personal driving experience using the standard dynamic handling system. Audi drive select influences the characteristics of both the engine and the steering. What’s more, the system also adapts the characteristic curve for shifting, as well as the exhaust flaps and further optional modules to suit the four modes: auto, comfort, dynamic and individual.
The front strut domes are made of highly integrated cast aluminum parts. Compared to sheet steel components made of many individual parts that are welded together, they are eight kilograms (17.6 lb) lighter. This construction allows a very stiff connection between the upper links and the body for the best-possible steering response - optimal conditions for dynamic handling.
