BMW M3 and M4: which is best?
M Division has been in the laboratory cooking up turbos. Ollie Marriage investigates…

What is it with this corner of Portugal? First the gorgeous N2, now the plunges and crests of the scintillating Portimão race track. The Yas Marina Blue four-door has been traded for an Austin Yellow two-door. The colours are better than those crass, clumsy names, but I can’t see either being a top choice in Britain. Out here, the harsh sunlight is pinging on the yellow paint, and the M4 seems to bathe in its own acidic halo.
But we need to venture beneath the skin again. For the first time on an M3, both front and rear subframes are solid-mounted to the central monocoque to increase stiffness. No bushings at all. Open the bonnet, and instead of a plain strut brace, a sinuous carbon-fibre construction artfully curves itself around the bay, strengthening the bonds between chassis, suspension turrets and engine carriers. I’m sure it’s not a coincidence that the carbon weave looks like snakeskin.
