BMW Details Quad-Motor Hardware and Special Battery for Next M EVs

Prototypes preview per‑wheel control on a new 800‑volt platform, with first road cars expected in 2027.

Overview

  • BMW’s M Neue Klasse prototypes use four motors—two compact drive units with one motor per wheel—for precise torque vectoring, with the rear axle able to decouple for rear‑drive behavior.
  • The high‑voltage system runs at 800 volts with a battery pack exceeding 100 kWh that features a bespoke cell chemistry aimed at higher sustained power, quicker charging and stronger energy recuperation.
  • Vehicle functions route through four centralized control units dubbed Superbrains, with a dedicated dynamics computer coordinating motors, braking, recuperation and steering; BMW says responses are significantly faster than prior systems.
  • The battery housing is structurally integrated with the suspension and body to increase stiffness, and BMW’s refined natural‑fiber material claims carbon‑fiber‑like properties with roughly 40% lower CO2e.
  • BMW indicates base Neue Klasse production is rumored to begin in Munich this summer, while the first M‑badged electric models are expected on roads in 2027.
