BMW’s M division is writing a new chapter in one of its most celebrated stories. The next-generation M3 Sedan—known internally as the G84—is officially in development, and yes, it will still pack an internal combustion engine. BMW M CEO Frank van Meel has confirmed the car’s existence, and now, thanks to a set of spy shots, we’re getting our first look at the next evolution of Munich’s performance icon in motion.
The Mule Takes Shape
The prototype recently spotted in testing isn’t yet wearing its final production skin. Instead, it’s cloaked in a mix of widened fenders, temporary panels, and development camouflage—classic BMW pre-production attire. Even so, its proportions tell a story: this M3 has a broader stance and a more planted look than the current G80 model, signaling tweaks to both chassis geometry and suspension setup.

Peek closer, and you’ll notice familiar M hallmarks. The test car rides on lightweight M aluminum wheels shod in wide rubber, with cross-drilled brake rotors and massive M calipers visible behind them. Around back, the quad exhaust setup—a tradition stretching back to the E46 M3—leaves no doubt about what kind of prototype this is.
A New Face for the M3
Underneath the camouflage, there’s a hint of what’s to come for BMW’s design language. The G84’s front end appears to move away from the polarizing, oversized kidney grilles of recent M models. Instead, the prototype shows an elongated, horizontal grille layout, reminiscent of the Neue Klasse concept cars and the upcoming all-electric M3 (ZA0). Slim, dual-LED headlight units flank the grille, though the rest of the bumper design remains under thick covers.
From the side, flush door handles further tie this prototype to BMW’s future design direction, while at the rear, a subtle trunk lip and the signature M quad pipes carry the brand’s DNA forward. The taillights are still heavily disguised, suggesting BMW isn’t ready to show off the final light signature just yet.
Under the Hood: Six Cylinders, Now Electrified
While the exterior still hides in plain sight, insiders are already sketching the G84’s mechanical blueprint. Expect a 3.0-liter inline-six engine, likely an evolved version of the S58 unit, paired with a 48-volt mild-hybrid system. The small electric assist won’t turn the M3 into a hybrid heavyweight but will instead sharpen throttle response, smooth out low-end torque, and improve efficiency—similar in philosophy to Porsche’s upcoming 911 Hybrid.
Sources suggest power will start around 525 horsepower, with higher-output versions pushing closer to 560 hp. The hybrid integration isn’t about chasing numbers; it’s about maintaining balance, response, and precision—the qualities that have always defined the M3’s character.
Farewell, Manual
There’s one inevitable casualty of progress: the manual transmission. The new M3 will reportedly launch exclusively with an eight-speed automatic paired with xDrive all-wheel drive. With the G80/G82 M3/M4 and G87 M2 marking the end of manual M cars, the G84 will carry the torch for BMW’s performance future without the clutch pedal. Purists, take a deep breath—this is the reality of the modern performance car landscape.
Why Not Plug-In?
In contrast to the larger M5, which embraces a plug-in hybrid system, the M3 will deliberately avoid the PHEV route. BMW’s engineers argue that the extra battery weight and packaging demands would dull the car’s agility and compromise its track-day readiness. Instead, the lighter mild-hybrid setup offers a way to meet tightening emissions targets without sacrificing the M3’s razor-sharp handling.
The Road Ahead
The G84 M3 isn’t expected to debut before 2028, but its early test outings are a clear sign that BMW intends to keep the M3 nameplate alive well into the hybrid age. The brand’s challenge is clear: merge cutting-edge efficiency tech with the raw, emotional performance that made the M3 a legend.
If these first glimpses are any indication, BMW might just be on the right track—literally. The M3’s next chapter won’t abandon its roots; it will evolve them, bridging the past and the future one turbocharged, electrified rev at a time.
