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.
"The new Audi RS5 Coupe is the gran turismo among the RS models from Audi Sport. The high-performance Coupe combines elegant aesthetics with high everyday usability. The car‘s V6 bi-turbo has been developed from the ground up and provides significantly more performance coupled with higher efficiency," said Stephan Winkelmann, CEO of Audi Sport GmbH, in describing the new model.
Sporty accents on the short rear end come in the form of the RS-specific diffuser insert, the oval tailpipes of the RS exhaust system and the vertical air outlets on the outer edges of the LED rear lights. A surface-mounted spoiler lip in black, or optionally in carbon, rounds out the image.
