BMW reveals technical details for the electric M3 sedan ahead of 2027 launch

BMW has revealed new technical details of the upcoming M3 EV, confirming a quad-motor AWD setup and a track-ready high-voltage battery ahead of its 2027 launch.

BMW has been working on the electric M3 sedan for quite some time, with the first spy shots emerging in late 2024. Two years in, the German carmaker has shared new technical details on the upcoming high-performance EV, which will mark the M brand’s entry into the electric era. The upcoming BMW M3 EV will be launched in 2027 and is being developed on Neue Klasse technology.

The BMW electric M3 will debut in 2027 as the brand’s first fully electric M model developed on the Neue Klasse platform

BMW iM3: Quad-motor dynamics

BMW’s upcoming electric M3 will feature a quad-motor electric drivetrain with independent torque control at each wheel

The electric M3 will be BMW M’s first fully electric vehicle built from the ground up, and as such, it is expected to uphold the brand’s reputation of delivering driver-centred performance and vehicle dynamics. The sedan will be underpinned by an 800-volt Neue Klasse architecture that features a four-motor electric drivetrain, with two electric motors on each axle enabling electric all-wheel drive. This configuration will allow precise torque control at every corner, enhancing traction, stability and overall cornering dynamics.

The four-motor setup allows the car to drive around in AWD whenever more traction is required or send power exclusively to the rear wheels. The front axle can be decoupled, allowing the rear wheels to take over when it’s time to save up some range or take the car drifting. The electric M3 will further feature drive mode presets, which can simulate gearshifts and the sounds to make the EV feel more engaging.

BMW iM3: Centralised electronics architecture

The electric M3’s high-voltage battery is designed for track use and will act as a structural component of the chassis

The iM3 will introduce a centralised architecture for its electronics, controlled by four high-performance computers dubbed ‘Superbrains’. These unite computing power for the driving dynamics, automated driving, infotainment and comfort functions. All of the driving systems are managed by a dedicated Heart of Joy control unit that calibrates power output, braking and energy regen levels. BMW claims this design allows for faster data processing and swifter software updates.

BMW iM3: High-voltage track-ready battery

The iM3's Gen6 high-voltage battery will have over 100 kWh of usable energy content and will act as a structural member of the car

An electric M3 will not be at home until it is taken to the track, which means that BMW has designed its battery to do just that and deliver the performance on demand. The M eDrive system will come with a Gen6 high-voltage battery, which is said to offer over 100 kWh of usable energy. The battery’s cooling system and cell chemistry have been adapted to support higher peak outputs and charging power than the regular electric 3 series sedan, and it is said to offer the highest energy recuperation levels. BMW added that the battery will be employed as a structural member of the iM3 and will add to the chassis stiffness and dynamics.

Further details on specifications and pricing have not been made public and are expected to arise closer to the market launch of the BMW M3 electric.
