AutoExpress UK pits the new BMW M4 against the Porsche Cayman S PDK and Audi RS5.

A rear-wheel drive vehicle, the Porsche Cayman S is powered by a naturally aspirated 3.4 liter six-cylinder engine outputting 320 horsepower and 370 Nm of torque.  While the Cayman is not always thrown in the same category as the M4 or RS5, on paper it can be described as a competitor.

Now when it comes to the M4 and RS5, at a first glance, there are a number of commonalities and similarities between the two cars, such as the dimensions: just over two centimeters separate the two also a small difference in engine performance – only 19 hp between the counterparties.

But there are a series of major differences, starting with the all-wheel drive on the Audi RS5 while the M4 stays true to BMW’s rear-wheel drive architecture. The Audi RS5 also comes with a 4.2 liter V8 engine. The RS5’s engine makes 450 horsepower and 317 lb-ft.

Manual transmission or 7-speed DCT for the M4, only a 7-speed S tronic DCT for the RS5.

So which one takes the win?


1st: BMW M4

Fans of fast BMWs should rejoice, because the new M4 is one of the best M cars yet. It wraps up supercar-rivalling performance in a practical four-seater body. It’s not cheap, but few cars provide as much performance per pound.
