New BMW M4 vs Mercedes-AMG C63: practicality
The M4 is a new range-topping version of our reigning Coupé of the Year, but is it better than its arch-rival from Mercedes' AMG performance division...
Space and practicality
Front space, rear space, seating flexibility, boot
As well as having the performance to show bespoke sports cars like the Alpine A110 and Porsche 718 Cayman a clean pair of heels, the M4 and C63 are in another league when it comes to practicality. Up front, for example, both will comfortably accommodate a pair of six-footers, thanks to seats that go back a long way and comparatively high rooflines. That said, the C63’s optional panoramic glass roof does rob a bit of head room (with a carbonfibre roof as standard, the M4 doesn’t give you the option of a sunroof at all).
Storage space in both cars is also pretty good. You get reasonably sized door pockets, deep central storage bins and cubbies in front of the cupholders. In those cubbies, you’ll find wireless charging pads that will charge your electrical devices without you having to plug them in; this is particularly handy in the M4, thanks to its wireless smartphone mirroring software.
In the rear, meanwhile, the M4 pulls out more of a lead. Not only does it offer a little extra shoulder room, but it has far more head and leg room – the latter allowing taller folks to lounge out.
The M4 has a slightly more practical boot, too, with its wide aperture and relatively square shape allowing us to fit seven carry-on suitcases, versus six in the C63. Both cars get split-folding rear seats, but the M4’s fold in a more versatile 40/20/40 configuration as opposed to the C63’s more traditional 60/40 set-up.
