Power will come from a naturally aspirated 4.2-liter V8 that produces 331 kW (444 hp / 450 PS) and 430 Nm (317 lb-ft) of torque. I was really hoping for a down tuned V10 TFSI or V8 TFSI, but if they put that powerful engine in the Audi RS5 then it will be too expensive and will step into R8 territory. The good news is that the 4.2 V8 will produce 450Ps and that is 30ps more than the current BMW M3 which the RS5 is aiming at.
RS5 customers will get a seven-speed S tronic DSG 7-speed transmission which allows the 1,725 kilogram (3,803 pound) coupe to accelerate from 0-100 km/h(0-62mph) in 4.6 seconds, before topping out at an electronically limited 250 km/h (155 mph). Audi can even remove the limiter if you pay extra.But despite the enormous power; Audi says that the RS5 will consume 10.8 liters of petrol per 100 km (21.78 US mpg).
