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.
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.
Both turbochargers of the 2.9 TFSI unit are centrally positioned inside the V of the engine and each of them supplies a single cylinder bank. The B-cycle combustion process with central direct injection represents a new level of efficiency within the RS family. In the NEDC, the V6 bi-turbo consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams of CO2 per kilometer (317.0 g/mi). This is an efficiency gain of 17 percent over the previous model. Also beneficial for the new Audi RS5 Coupe is a drastic reduction in weight. The vehicle weighs in at 1,655 kilograms (3,648.7 lb) - 60 kilograms (132.3 lb) less than previously. A carbon roof with visible fiber structure is also available as an option.
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.
