The rivalry between Audi and BMW was put to the test once more, this time with the RS5 Coupe and M4 Competition Pack respectively.

While the two cars have similar outputs, things are quite different under the skin. Ingolstadt’s premium compact coupe uses the Quattro AWD system, tweaked by the Sport division, whereas the M Division has stuck to good old rear-wheel drive.

Performance-wise, there’s not much of a difference between the two. The RS5 Coupe takes 3.9sec for the 0 to 100km/h (0-62mph) acceleration, and uses a bi-turbo 2.9-liter V6 with 450PS (444hp) and 600Nm (443lb-ft) of torque. The BMW M4 Coupe Competition Pack has the exact same horsepower, 50Nm (37lb-ft) less of torque and is just 0.1sec slower from 0 to 100km/h (0-62mph).

Moreover, adding the Competition Pack to the Bimmer makes it more expensive, but the bundle of upgrades does bring a few interesting items like adaptive M Suspension, reconfigured driving modes, an M sports exhaust and sportier front seats.

Another aspect that should be taken into consideration is the weight, with the Audi tipping the scales at 1,620kg (3,571lbs), while the BMW is lighter at 1,500kg (3,307lbs).

These two then seem quite evenly matched. Their drag race did, of course, have a winner, but it was oh so very close…
