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 bi-turbo‘s power flows through a sportily-tuned, eight-speed tiptronic transmission with optimized shift times and on to the quattro permanent all-wheel drive which features a self-locking central differential. The drive forces are asymmetrically distributed between the axles in the ratio of 40:60. Dynamic handling with optimum traction and the best-possible levels of safety are thus guaranteed. Audi Sport also offers an optional rear sport differential.
The fast, spontaneously and sportily shifting eight-speed tiptronic with optimized shift times is standard on the new Audi RS5 Coupe. The layout of its gear sets and shifting elements results in low drag torques and thereby to a high efficiency level. Its large number of gears very frequently makes it possible to operate the engine close to its ideal load point. The lower gears have short, sporty ratios, while the upper gears are long in order to reduce revs and fuel consumption.
