Immense pulling power and high output combined with efficiency: Even after the revision, the output of the 2.9 TFSI remains unchanged at 331 kW (450 PS). The V6 twin-turbo delivers between 1,900 and 5,000 rpm; during this process, each charger supplies a cylinder bank with compressed air and 600 Nm (442.5 lb-ft) of torque is supplied to the crankshaft. Both RS models catapult themselves from zero to 100 km/h (62.1 mph) in 3.9 seconds; on request, Audi Sport GmbH can raise the top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).<br /><br />An eight-speed tiptronic that has been tuned for sportiness transmits the forces of the engine; the driver can control it using enlarged aluminum shift paddles. The quattro permanent all-wheel drive gives the RS5 a special place in the segment. In normal driving operation, the power distribution between the front and rear axle is 40:60 - this asymmetrical dynamic torque distribution leads to sporty, rear-biased handling. If necessary, the center differential can redirect up to 70% of the forces toward the front or up to 85% of the forces toward the rear. With the optional sport differential, which actively distributes torques between the wheels of the rear axle, the dynamic handling is increased even further.<br /><br />In the WLTP driving cycle, the Audi RS5 Coupé consumes just 9.1 l (2.4 US gal) of fuel per 100 km (62.1 mi); the RS5 Sportback consumes 9.2 l (2.4 US gal); the two vehicles thus emit 208 g/km (334.7 g/mi) and 209 g/km (336.4 g/mi) of CO2 respectively.
