These Fat Fenders Tell You Everything About This M Car’s Mission

- BMW’s electric M3 has been spotted with minimal disguise for the first time.
- The prototype dropped the previous riveted arches for real, one-piece fenders.
- A quad-motor drivetrain should deliver 700+ hp and torque vectoring capability.
BMW’s Neue Klasse 3-series sedan is just around the corner, but barrelling up to the next curve down the road, and coming in hot, is its M3 brother. The M3 will be available with both electric and ICE power, and our spy photo team has has papped the EV (possibly named the iM3, following a recent BMW trademark) wearing its fat production fenders and no distracting M-color camouflage for the first time.
Although we’ve seen electric M3 test cars before, they’ve always been fitted with riveted arch extensions or fender graphics that make it hard to see what the shape of the rear quarter panels. But now we get to see the true contours of the real fenders that will add more than 3 inches (76 mm) of girth versus a stock i330 sedan.

The extra width of the front fenders is fairly subtle, though combined with the suspension drop gives the M3 a much lower, wider and meaner look than the i330 prototypes we’ve seen. But there’s no missing the rear-end makeover. Those new swollen fenders are huge, meaning the charging flap on the nearside rear quarter lies almost at 45 degrees.
How do we know this is the electric M3? There’s the lack of tailpipes, of course – we see a diffuser for the first time on a prototype – but that’s not the only clue. Electric versions of the Neue Klasse 3-series, including the M3, have a much shorter gap between the front door and front wheel arch opening, a more sloping windshield and a forward-angled window post in the middle of the rear door. On combustion-powered NK Threes, which get an updated version of today’s 3-series’ CLAR platform, rather than the Neue Klasse architecture, that window post is vertical.













Though this M3 prototype gives us a look at the production fenders, it’s still keeping plenty of secrets – it won’t be launched for at least 18 months, after all. The front and rear bumpers remain literally under wraps and we’re yet to see the final design for the front and rear lights.
But one shot showing a glimpse of the interior through the passenger window confirms the presence of the same Panoramic iDrive centrally-mounted tablet touchscreen and full-width head-up display at the base of the windshield that BMW showcased at CES in Las Vegas at the beginning of 2025.
Under the skin the electric M3 will have as many as four electric motors delivering just over 700 hp (710 PS) in standard form, while the ICE version will get a mild-hybrid six-cylinder engine.
