The next BMW X3 M will make at least 800 horsepower, according to sources speaking to BMWBLOG. That’s roughly 300 hp more than the last X3 M Competition. It also beats the 738 hp of the XM Label Red, the SUV BMW M sells as its flagship.
A compact crossover is about to outrun the division’s halo car. BMW has not officially confirmed any of this.
The car, codenamed ZA5, is reportedly due for production in November 2027 at Debrecen, Hungary, the same plant that builds the iX3. The electric X4 M, ZA7, is said to follow down the same line that month. US deliveries should land in early 2028, though that timing is soft and could slip.
There’s no S58 inline-six this time. There’s no gasoline X3 M coming at all.
The X3 M50 xDrive, rated at 437 hp in the US, is as far as the six goes in this generation. Anyone who wants the old formula has one route left, and it runs through a used F97.
In place of the engine come four motors, one per wheel, borrowed from the electric M3. BMW has confirmed that layout for the M3, including a front axle that decouples for pure rear-wheel drive. The company has also said every full electric M car will use four motors.
That puts the real work inside Heart of Joy, the Neue Klasse central computer that handles torque distribution and suspension. With no mechanical differential doing the thinking, software decides how this thing behaves at the limit.
The badge will read X3 M, not iX3 M. BMW treats the name as belonging to the car rather than the drivetrain, the same logic M CEO Frank van Meel applied to the M3 at Le Mans in June. It also spares an iX3 M from sitting awkwardly beside an iX3 M60.
That M60, revealed in October, makes 603 hp. The gap to the full M car is about 200 hp.
Here’s the friction. Van Meel has called rivals’ four-digit outputs “more or less absurd,” arguing the hard problem is shedding heat, not making power. The M3’s brief is a car that can run several track sessions without fading.
The X3 M gets the tougher version of that assignment. BMWBLOG expects the M3 to weigh more than 2,000 kg, built around an M-specific structural pack with more than 100 kWh usable from performance Gen6 cylindrical cells. A taller SUV carrying a battery at least that large will weigh more.
If the rear-drive mode carries over as expected, BMW will sell an 800-plus-hp family SUV that can send everything to the back wheels. That’s either brilliant or unhinged, and probably both.
Prototypes caught in Munich and near the Nürburgring in late 2025 showed a power dome on the hood, an aggressive rear apron with a central diffuser scoop, and big drilled discs behind blue M calipers. The sedan’s prototypes wear a functional V-shaped vent instead of a dome. That suggests the SUV may keep a front trunk the M3 likely gives up.
Inside, expect the iX3’s Panoramic Vision display and iDrive X with M seats and trim. M recorded its old six, V8 and V10 for a soundtrack, then shelved the idea. Simulated gear changes stay.
Pricing is unannounced. The iX3 50 xDrive starts at $61,500 and the X3 M50 xDrive at $67,500, both before destination. The M car should sit well above both.
The target is the Porsche Macan Turbo Electric, with 630 hp on overboost and a 3.1-second run to 60 mph. On paper, the BMW leads by about 170 hp. Van Meel has already said paper is not where he intends to win.
