From 1,900 to 5,000 rpm, the 2.9 TFSI supplies the crankshaft with an impressive 600 Nm (442.5 lb-ft) of torque, which is 170 Nm (125.4 lb-ft) more than on the previous model. With its 331 kW (450 hp) - which equates to a power ratio of 155.5 hp per liter displacement - the unit accelerates the new RS5 Coupe from zero to 100 km/h (62.1 mph) in 3.9 seconds and thus six tenths of a second faster than before. If the customer orders the RS dynamic package, Audi increases the electronically restricted top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).
The designers drew inspiration for the RS5 Coupe from the distinctive racing details of the Audi 90 quattro IMSA GTO. Massive air inlets with the honeycomb structure typical of RS models characterize the front end of the car. The Singleframe radiator grille is much wider and flatter than in the base model. Next to the headlights are additional lateral air intakes and outlets; tinted bezels differentiate the optional Matrix LED headlights. quattro blisters on the flanks emphasize the pronounced bulges over the wheel arches, which have been widened by 15 millimeters (0.6 in). As standard, these house 19-inch forged aluminum wheels, with 20-inch wheels available as an option. A sporty conclusion to the vehicle is provided by the RS-specific diffuser insert, the oval tailpipes of the RS exhaust system and a surface-mounted spoiler lip. With a length of 4,723 millimeters (185.9 in), the new Audi RS5 Coupe is 74 millimeters (2.9 in) longer than the previous model.
An important component of the B-cycle combustion process is the central position of the injectors in the combustion chamber. In the area around the inlet valve, this makes possible a geometry which, in interaction with the inlet ports, allows for targeted mixing up of the gas charge. The common-rail system injects the fuel into the combustion chamber with 250 bar of pressure - the high injection pressure ensures a homogeneous spray pattern and consequently a uniform propagation of the flame front.
