The front strut domes are made of highly integrated cast aluminum parts. Compared to sheet steel components made of many individual parts that are welded together, they are eight kilograms (17.6 lb) lighter. This construction allows a very stiff connection between the upper links and the body for the best-possible steering response - optimal conditions for dynamic handling.
The 2.9 TFSI V6 bi-turbo engine, which Audi developed from the ground up, offers sharp increases in power and efficiency as well as an incomparably full-bodied RS sound. It delivers 331 kW (450 hp). And it‘s peak torque of 600 Nm (442.5 lb-ft) - 170 Nm (125.4 lb-ft) more than the previous model - is available across a broad engine speed range from 1,900 to 5,000 rpm. The top model in the A5 family sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds, and reaches a top speed of 250 km/h (155.3 mph) - with the optional RS dynamic package it can even reach 280 km/h (174.0 mph).
The high-output V6 doesn’t just impress with its strong performance, but also with its high level of efficiency. In the NEDC, it consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams CO2 per kilometer (317.0 g/mi). This means a 17 percent consumption saving compared with the previous model. A decisive factor in this is the new TFSI combustion process from Audi, which is known as the B-cycle. It has been specifically designed for the partial-load range, which is the predominant operating mode during normal use.
Just like the entire A5 model family, the new Audi RS5 Coupe also benefits from a drastic reduction in weight. It weighs in at 1,655 kilograms (3,648.7 lb) - 60 kilograms (132.3 lb) less than previously. The body of the new RS5 Coupe is among the lightest in the segment. Thanks to geometrical lightweight construction and an intelligent mix of materials, it weighs 15 kilograms (33.1 lb) less than the body of the previous model. The module cross member under the instrument panel, for instance, consists of extruded aluminum profiles and sheets, and the front cross member is an extruded profile.
