Chances are BMW doesn't want you to see this.
The next-generation BMW M4 Convertible is coming soon. Our spy photographers have caught nearly advanced prototypes out testing recently, so we already have a pretty good idea of what the final design will look like. Lo and behold, the new M4 drop-top will share the radical front-end styling found on the coupe. But will there be other changes as part of the coupe to convertible transformation?
Thanks to the folks at the i4talk forum, we have our answer. A forum member managed to uncover the patent photos filed with the European Union Intellectual Property Office and despite sharing a front-end, the convertible differs from its coupe sibling in several ways after the A-pillar.
There's a new upward sweeping beltline that wraps around the car to the trunk, just like in the regular new 4 Series Convertible. That trunk also boasts a unique design because it also must accommodate the folded fabric soft top. The outgoing M4 has a retractable hardtop but BMW felt it necessary to cut weight for the new model. There's also a brake light integrated into the rear spoiler. Other rear design elements from the coupe, such as the quad-pipe exhaust system and diffuser, are carried over.
The engine, of course, will be a twin-turbo 3.0-liter six-cylinder with 473 horsepower and 406 lb-ft of torque. Like the coupe, the convertible is expected to come offered with a choice of either a six-speed manual or an eight-speed automatic transmission.
The Competition model will see power increased to 503 hp and 479 lb-ft plus having the eight-speed route power to an optional all-wheel-drive system instead of just the rear wheels. All other major details will be revealed sometime early next year when the 2021 M4 Convertible has its official debut.
As is normally the case, expect the convertible to carry a premium price tag over the coupe, the latter of which begins at $71,800. A fully-loaded 2021 M4 Competition Convertible could even reach as high as $85,000.
