Passenger & boot space
How it copes with people and clutter
As well as having the performance to show purebred sports cars like the Alpine A110 and Porsche Cayman a clean pair of heels, the BMW M4 Competition is in another league when it comes to practicality.
Compared with the standard BMW 4 Series, the only difference is its wider sports front seats. The optional M carbon bucket seats we tested give the driver and passenger more lateral support, yet still offer ample head and leg room for six-footers.
