New BMW iM3 Prototype: Everything We Know About the Quad-Motor Beast

The electric BMW M3 is no longer just a concept—it is on its way, and it is coming in strong. BMW’s M division is going all out, starting with a quad-motor layout aimed at delivering serious performance and next-level torque vectoring. Behind it all is a newly developed control system that seamlessly manages those four motors, unlocking handling capabilities that would be impossible in a gasoline-powered model.

Although we have seen some early prototypes on the road, those versions were rough development mules. But now, things are getting more serious. Recent spy shots reveal a much more refined vehicle that appears much closer to the final production version, potentially named the iM3.

The prototype is showing off some seriously aggressive styling. The widened fenders are no longer makeshift bolt-ons—they are fully integrated and look production-ready. These wide fenders serve a purpose too, housing a staggered tire setup with 275/35R20 rubber up front and 295/35R20 in the rear, mounted on deep-dish wheels. The wheels themselves are likely not final, but the dimensions reflect the performance potential.

Look past the wheels and you will notice massive brake rotors paired with equally large calipers. There is talk that this prototype uses in-wheel electric motors, a design BMW is developing for better efficiency in future Neue Klasse vehicles. Regardless, BMW M has made it clear—electric M cars will feature four motors, no exceptions.

In terms of design, the M3 electric adopts a wider, shorter grille. It is a departure from the controversial tall grille of the current M3, and it already looks like it will be better received. The overall body shape leans heavily into BMW’s new design language, especially from the Neue Klasse platform.

Do not worry about the odd taillights or the bulky rear bumper. Those are temporary covers and camouflage to hide the production design. The taillights are placeholders, and the exaggerated shapes in the rear will be removed before the final version hits showrooms. If you are trying to guess where the real bumper ends, look for the seam between the disguised pieces at the back.

BMW has not officially announced when the all-electric M3 will debut, but judging by the level of detail on these prototypes, the launch could be sooner than expected. Right now, 2026 seems like a strong possibility. And for purists, a combustion-engine M3 or M4 is still expected to be sold alongside it, built with a different body and older tech.
