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.
In the induction tract, the intake valves close well before the piston reaches bottom dead center. This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
A further efficiency component of the 2.9 TFSI is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil is warmed up as quickly as possible. The exhaust manifolds are integrated in the cylinder head, and coolant circulates around them which helps ensure rapid warming up. When the engine is warm, this technology lowers the exhaust temperatures - consumption drops drastically, especially when driving in a sporty way. The great efficiency of the V6 bi-turbo is also partly to do with low friction. For example, the fully adjustable oil pump only builds up as much pressure as necessary.
