All M4s get three settings for the electrically assisted power steering and all have three modes of firmness on the adaptive dampers (as opposed to the usual two). All UK cars, meanwhile also come with 19-inch alloy wheels as standard, although the GTS rides on 20ins shod in Michelin Pilot Sport Cup 2 tyres.
Your options are Comfort, Sport and Sport+, but even in Sport+ the BMW is bearable on the smoothest UK roads. Generally, though, we found ourselves picking Comfort on the road and Sport+ on a circuit.
The steering is weightier in its latter setting but feel remains similar in both, the only difference being that the signals reach you at a different amplitude. That’s fine by most of today’s standards, but it would send an E30 driver weeping into his Warsteiner at the inertness of it all.
Control of body movements is very good, though, for a 1600kg car, and the M4 drives with a maturity and isolation that is the logical progression from its predecessor.
Driving an M4 back to back with an M240i brings that into sharp context; the M4 feels like a bruising cruiser next to the more lithe, more agile, more compact M240i, although the long-anticipated M2 muddies those waters somewhat.
