British magazine Auto Express decided to set up a track duel between the well-established Audi RS5 and a newcomer, the BMW M4 Coupe. Owen Mildenhall was in charge of comparing the two high performance coupes from Ingolstadt and Bavaria and picking a winner is hard to do since both cars live up to their promises and in the end it could be a matter of tastes.
To review their specs, the Audi RS5 Coupe is motivated by a naturally-aspirated 4.2-liter FSI engine delivering 450 PS (331 kW) at 8,250 rpm and a maximum torque of 430 Nm (317 lb-ft) between 4,000 rpm and 6,000 rpm. All that power is channeled to both axles through a 7-speed S tronic gearbox which enables the hot coupe to hit 62 mph (100 km/h) in 4.6 seconds before topping out at 155 mph (250 km/h) or 174 mph (280 km/h) if ordered with the optional package.
As far as the 2014 BMW M4 Coupe is concerned, this is a rear-wheel drive coupe and comes with a TwinPower Turbo 3.0-liter inline-6 engine generating 431 PS (317 kW) between 5,500 rpm and 7,300 rpm and a peak torque of 550 Nm (406 lb-ft) available between 1,850 rpm and 5,500 rpm. With the optional seven-speed M DCT gearbox, the M4 will hit 62 mph in 4.1 seconds or in 4.3 seconds with the standard 6-speed manual ‘box. Top speed stands at the same 155 mph / 174 mph as in the Audi RS5 Coupe.
In conclusion, the RS5 has a little bit more horsepower but is considerably down on torque compared to the M4. In the 0-62 mph sprint, the M4 manages to be considerably quicker but this is understandable taking into account the M4 is a fresh product while the RS5 is starting to show its age.
