Spy photographers recently snapped some pics of the 2021 BMW M4 Convertible prototype near Munich. Even the vehicle’s heavy camouflage couldn’t disguise the evolutionary design, which resembles cues from the Concept 4.
The main attraction of this prototype is its massive grille that looks like a giant peanut. Seriously, it’s absurdly large. Adrian van Hooydonk might say the comically big grille was a purposeful part of BMW’s continual evolution — but everyone is calling BS. We’re talking 24/7 grille, people. Soon there will be nothing else — only grille.
Of course, the M4 does have some pretty attractive features (however overshadowed they might be by ). Slender headlights and a bulky front bumper flank it. A high-performance system with blue calipers backs the lightweight brakes. The shots give us a good look at the body lines, fender flares, exhaust setup and lip spoiler. The back end is tame, but the four-pipe exhaust system suggests hidden power under the hood. Plus, you can’t take your eye off the rear spoiler, which features a third brake light.
Under the hood is a 3.0-liter TwinPower Turbo engine. It generates 473 horsepower and 442 lb-ft of torque. Or, if the Competition Package is more your style, you’ll enjoy 503 horsepower and 442 lb-ft of torque.
The cabin’s interior will look a lot like the 3-Series. You can expect a 12.3-inch digital instrument cluster display and a 10.25-inch infotainment system. The biggest challenge is the return of the retractable soft top. While the top will reduce weight, you’ll also notice more prominent blind spots.
The Debut of the BMW Concept 4

BMW unveiled the Concept 4 at the Frankfurt Motor Show in September of this year, which previews the next-generation 4-Series. The company describes the design as an interpretation of their commitment to the magic of coupe driving.
There’s been a lot of rumors surrounding the M3 and M4. BMW has yet to release details about the powertrain. However, you can expect four- and six-cylinder motors.
Reports suggest the cars will offer rear and all-wheel drive, though it’s not clear if this feature is available for the M4 Convertible. You’ll also be able to choose between a six-speed manual and an eight-speed automatic.
Frank Van Meel, head of BMW M, claims the company will adopt a four-tier model strategy. Along with the M3 and M4 Standard and Competition guises, we’ll also see a CS and CSL version.
The Competition will offer more power than the standard version, while CS will showcase track focus and weight-saving measures. The CSL’s durable design is meant to replace old GTS models — complete with improved aerodynamics, stickier tires and less weight.
Grilles, Grilles, Grilles
Critics praise the vehicle for its low roof, sharp lines and rear deck. Honestly, the only judgments I’ve heard made about it relate to the grille. Based on spy photos and videos of the upcoming M3 and M4, the peanut-shaped feature is a definite possibility for the Concept 4.
Adrian van Hooydonk, BMW’s design chief, claims he knew the massive grille would draw backlash. Still, he’s hurt by the comments, saying the design was an attempt to turn the original kidney concept into a pair of lungs — meant to represent a horse.
Hooydonk suggests the car’s complaints come from different customer priorities around the world. The loudest criticisms hail from Europe, where drivers like sleek black designs and prefer to go unnoticed. The market, which is strongest in the U.S. and China, backs up this claim.
The Future of the 2021 BMW M4
Priced starting at $70,000, the M3 and M4 will keep facing strong competition from Audi, Lexus and Mercedes. We’ll have a better idea of what to expect from the 2021 BMW M4 when the M3 debuts next year.
