BMW announced on Tuesday that its first all-electric M cars are slated for release in 2027, promising “unrivaled high performance” that aims to redefine the driving experience for enthusiasts.
Four-Motor Powertrain for Peak Performance
The upcoming electric M cars will feature a significant upgrade over standard Neue Klasse models, boasting a quad-motor powertrain. Unlike the iX3’s dual-motor setup, the M variants will equip each wheel with an independent motor. This configuration allows for precise, rapid control of each wheel, which BMW claims will result in driving dynamics far superior to current M cars.
“The unique concept lets us achieve performance levels you’ve never seen in a BMW M production car as of now,” stated Philipp Brunn, head of the BMW M Neue Klasse project. This quad-motor setup positions BMW’s electric performance cars alongside niche hypercars like the Rimac Nevera, a notable departure from the tri-motor systems found in competitors like the Tesla Model S Plaid and Lucid Air Sapphire, and the truck-focused quad-motor vehicles currently available in the U.S.
BMW has developed new drive units, each housing two motors, two gearboxes, an inverter, and a lubrication system within a single unit. These units will be placed at both the front and rear of the vehicle. For improved efficiency during highway driving, the front axle can be mechanically disengaged. While specific power figures remain undisclosed, Brunn indicated that horsepower, torque, and acceleration will reach “new heights.”
Advanced Software and Simulated Driving Dynamics
In line with other Neue Klasse vehicles, the M cars will utilize a simplified, high-performance electrical architecture. This design consolidates vehicle functions into a few powerful computers, a departure from the numerous control units found in previous generations. This approach, similar to the “zonal architectures” used by Rivian and Tesla, is expected to enhance responsiveness and driving engagement.
“Benefits are the same as in the Neue Klasse models: faster data transfer between the control units, leading to a clear performance gain for us,” Brunn explained. “The system is 10 times faster, which sharpens system responses, and by that, improving driving dynamics.” The “Heart of Joy” computer, central to powertrain and driving dynamics management, will feature software specifically optimized for the M cars.
To enhance the emotional connection for drivers, BMW is introducing simulated gear shifts and M-specific sounds for its electric performance models. This feature, pioneered by the Hyundai Ioniq 5 N and soon to be adopted by Porsche, aims to replicate the feel and sound of traditional combustion engines. BMW plans to draw from its rich history of engine sounds, potentially offering drivers choices between the distinct notes of a vintage BMW 2002 and a modern V-8 M5.
High-Performance Battery and Chassis Enhancements
The 800-volt powertrain will be supported by an upgraded Neue Klasse battery pack. This pack will feature cells optimized for high power delivery over energy density, incorporating enhanced cooling systems. While this configuration will result in higher power output and faster charging, it may lead to a lower overall capacity and driving range, though BMW stated the pack will exceed 100 kilowatt-hours. The battery management system has also been revised to manage increased energy peaks.
Furthermore, the M variant’s battery pack will be more rigidly integrated with the vehicle’s chassis and suspension compared to standard Neue Klasse models, contributing to a stiffer and more performance-oriented structure.
