This beautiful M4 is fully equipped with navigation, backup camera, dual clutch automatic transmission, paddle shifters and driven by a drastically capable straight-six engine with two turbos and anti-lag. An engine that fires the car forward on a perfectly controllable hurricane at pretty well any point on the rev dial. But it’s an engine that although loud, doesn’t have the bewitching sound or - not quite - the chef’s-knife throttle response of its predecessors.
Of course in the convertible, you can take the roof down and get a bigger ear-canal load of its four tailpipes, which adds to the atmosphere. Or you can raise the well-insulated rigid roof, switch the powertrain button to a more civilised mode which closes the exhaust flaps, and use the M4 as a surprisingly civil yet rapid tourer.
