Innovative BMW M eDrive concept with fully integrated M Dynamic Performance Control.
The BMW M Neue Klasse has been developed from the ground up. At the core of the new architecture is BMW M eDrive, which is based on the BMW Gen6 technology of the Neue Klasse. Each wheel is driven by an electric motor. In combination with the M-specific control software of the ‘Heart of Joy’, the ‘BMW M Dynamic Performance Control’ unlocks completely new potentials in driving dynamics and safety for high-performance vehicles. Additionally, the system enables maximum recuperation and optimum traction right up to the limit, as well as a more direct response.
In all electric models of the BMW M Neue Klasse, two electric drive units on the front and rear axles, each with one electric motor per wheel, ensure driving performance expected from BMW M. Each of the four electric motors drives one wheel. This concept combines all the advantages of rear-wheel and all-wheel drive while enhancing driving dynamics on the road and racetrack. Additionally, the front axle can be completely decoupled. The result is BMW M’s renowned rear-wheel drive with its dynamic driving characteristics, enhanced efficiency, and increased range, for example, on longer motorway journeys. For the unmistakable BMW M driving experience and enhanced drivability, various predefined driving modes, simulated gear shifts, and a newly developed soundscape come into play. These are just a few examples of how BMW M channels pure emotion into the fully electric BMW M models, making it felt in every single drive.
The electric drive units of BMW M eDrive are characterised by high power density and are the most powerful drives BMW M has ever used. In both drive units, the electric motors are arranged in parallel, each delivering power to one gearbox per wheel. The drive units also integrate the inverter for controlling the electric motors and the oil supply. The system enables precise control of torque and power at each individual wheel, allowing for optimal traction, continuous torque distribution between the braking system and electric motors, as well as brake energy recuperation right up to the limit. The result is a driving experience in BMW M production vehicles that has never been achieved before.
Powerful high-voltage battery for high peak performance and faster charging.
The high-voltage battery, boasting over 100 kWh of usable energy as the powerhouse for the BMW M eDrive system, has also been specifically adapted to meet the demands of high-performance vehicles. The focus remains on compatibility with both road and racetrack use. This is achieved through a "Design to Power" approach, featuring a performance-optimized variant of the Gen6 cylindrical cell. Supporting this, the cooling system and the Energy Master — the highly intelligent control center of the battery located outside the battery pack — have been optimized for higher power outputs. With BMW M specific solutions, the Gen6 high-voltage battery in the fully electric high-performance models delivers even greater peak and charging performance. Additionally, within the Gen6 technology, the Neue Klasse models offer the highest recuperation values. The high-voltage battery housing also serves as a structural component of the vehicle and is connected to the front and rear axles. The higher resulting stiffness in the overall vehicle also leads to improved driving dynamics.
