Looks, power, spec and sound! Four words that sum this M4 Convertible up perfectly. With 630PS, 799Nm, M Carbon Bucket Seats, the Ultimate Package and M Carbon Exterior Package, this is far from your average M4 Cab. Tom Wrigley Stage 2 This car has been taken to another level by Tom Wrigley Performance, with the Stage 2 conversion producing a dyno-proven 630PS and 799Nm. The conversion includes: TWP Catless Downpipes TWP Single Mid-Pipe ECU Unlock Custom Stage 2 ECU Calibration Gearbox Calibration Dyno setup and verification And perform it does. The way this car surges forward puts it up there with some of the quickest cars we've had in stock, but it's the combination of that performance and the exhaust that makes it so addictive. Driving Leave it in Comfort and it hides its true colours remarkably well. It's still an M4 Convertible you could happily use every day. Then press M2. The exhaust barks into life, the throttle sharpens and the whole character of the car changes. Pull the downshift paddle and you're met with the kind of pops and bangs on the overrun that would make a WRC car proud. With the roof down, they hit differently. It's loud, dramatic and makes you want to find another tunnel just to do it all again. Specification It isn't just a basic M4 with more power either. The Ultimate Package brings Head-Up Display, Harman Kardon, Comfort Access, heated steering wheel, wireless charging, Parking Assistant Plus with 360° cameras and Drive Recorder. The M Carbon Exterior Package adds carbon front intakes, mirror caps, rear diffuser and spoiler. Inside you'll find Black and Silverstone Full Merino leather with M Carbon Bucket Seats, making the cabin every bit as special as the performance. History Backed by a Full BMW Service History, with its most recent oil service completed by Dick Lovett BMW. Summary This is what happens when you take an already brilliant M4 Convertible, specify it properly and then turn everything up a few notches. 630PS, 799Nm, roof down and an exhaust note that ensures every journey becomes an event.
