About This Car
503 horsepower, top down, and zero apologies — the M4 Cabriolet struts like it owns every zip code
503. That's the horsepower number stamped on this car's chest, and every part of the M4 Cabriolet is built to remind you of it. Drop the top and the twin-turbo inline-six gets louder, brasher, like it wants the whole boulevard in on the joke.
This isn't a softened, sunshine-only version of the M4 coupe — BMW barely touched the attitude. The snarl off the line still shoves you into the seat, the automatic gearbox still snaps through shifts like it's got somewhere to be, and the chassis still flexes hard through corners that would have a lesser convertible flexing its structure instead. Roofless cars usually trade rigidity for style. This one struts around that compromise, stiffened underneath so the steering stays sharp and the rear end stays honest even with the sky wide open.
The cabin doesn't whisper luxury — it flaunts it, sport seats gripping tight, carbon trim catching the sun, a stance that says money without saying quiet.
Sunbelt roads, valet lines, coastal highways at golden hour — this is where the M4 Cabriolet goes to be seen and heard. Confidence isn't optional equipment here. It's the whole point.
