The axle concept of the new RS5 Coupe enables optimal absorption of longitudinal and transverse forces. 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. Audi Sport offers the RS sport suspension plus with Dynamic Ride Control (DRC) as an alternative. It uses steel springs and three-stage adjustable dampers that are connected to one another via diagonal oil lines and a central valve. When cornering at speed, the valves regulate the oil flow in the shock absorber of the spring-deflected front wheel at the outside of the curve. They increase the support provided and reduce pitch and roll movements. They thus connect the vehicle more closely to the road and improve handling. A new damper generation with integrated control valve ensures much more noticeable spread between the individual modes of the Audi drive select system.
As an alternative to the further-developed electromechanical power steering, Audi 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. At the cornering limits, the system countersteers with tiny impulses, thus further boosting the dynamism and driving safety. In the dynamic setting within Audi drive select, the superposition of the dynamic steering is stiff in order to support a more sporty driving style.
The luggage compartment offers ten liters (0.4 cu ft) more volume than before. It now holds a best-in-segment value of 465 liters (16.4 cu ft). The tailgate opens automatically and the two-door Coupe can be ordered from Audi with optional sensor control. With this, a proximity sensor in the rear bumper reacts to a kicking motion. The tailgate unlocks and opens automatically if the optionally available advanced key is detected.
Each of the two turbochargers on the 2.9 TFSI is assigned to a single cylinder bank and can build up a maximum of 0.95 bar charge pressure. Like with all new V6 and V8 engines from Audi, the turbochargers are installed within the 90-degree angle of the cylinder banks, and thus the exhaust side of the cylinder heads is on the inside, while the intake side is on the outside of the engine. This layout enables compact construction and short gas flow paths with minimal flow losses - the 2.9 TFSI responds extremely spontaneously to movement of the accelerator pedal.
