The increased dimensions of the gran turismo, the 15-millimeter (0.6 in) longer wheelbase and more compact seats increase the space for the driver and passengers. The shoulder room in the front row of seats has been increased by 26 millimeters (1.0 in) and the knee room in the rear by 23 millimeters (0.9 in). The central armrest in the front with storage compartment, the big door pockets, two cup holders and a new, closed stowage compartment beneath the rotary light switch further increase the car‘s everyday usability. One standard feature offering additional convenience to the driver and front passenger is the seat belt height adjustment featuring extending and retracting power belt feeds. The rear bench seat provides space for two passengers and integrates a practical stowage tray between the two seats, as well as a folding armrest. The backrests can be folded forward in the ratio 40:20:40 using the remote unlocking feature in the trunk.
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.
In the classic Miller cycle, the reduced cylinder charge is detrimental to torque and power output. These aspects have been neutralized by Audi thanks to the implementation of turbocharging and the two-stage Audi valvelift system (AVS). The four camshafts of the 2.9 TFSI can each be adjusted by 50 degrees crank angle. At higher load and engine speed ranges, AVS closes the inlet valve later. The opening time increases from 130 to 200 degrees crankshaft angle, while at the same time the valve lift increases from 6.0 to 10.0 millimeters (0.2 to 0.4 in). Cylinder charging also increases considerably - the 2.9 TFSI revs up powerfully and delivers an impressive output.
