BMW M Is Testing a Quad-Motor EV Drivetrain in a Widebody i4


  • BMW M introduced it’s testing an all-electric high-performance prototype based mostly on the i4.
  • The automobile has a brand new all-wheel-drive setup with 4 electrical motors.
  • Digital testing and bench testing have already taken place, and this new testing will put the prototype by means of extra life like situations on the street.

    BMW’s M high-performance division is shifting additional down the trail towards electrification, if this i4-based prototype with a brand new quad-motor drivetrain is any indication. The prototype’s all-wheel-drive setup with 4 electrical motors means that future M EVs might be considerably extra highly effective than the present M-badged electrical choices, the 536-hp i4 M50 and the 610-hp iX M60. Each of those have dual-motor setups.

    BMW has not but stated precisely which type a future M EV might take, however the check mule is predicated on the i4 M50, with widened wheel arches to suit totally different entrance and rear axles. It additionally makes use of structural elements from the M3 and M4 to enhance torsional rigidity. Testing started in digital fashions and on check benches earlier than being placed on the street.

    Past offering extra energy, BMW says that having a motor at every wheel can even open the door for extra exact tuning, with the flexibility to immediately ship energy to particular person wheels. The 4 motors are related to 1 central management unit which determines the place to ship energy based mostly on elements like pedal place, steering angle, longitudinal and lateral acceleration, and wheel speeds.

    We do not know but precisely when this new powertrain will go into manufacturing, however EVs have already begun to disrupt BMW’s efficiency hierarchy. Though the i4 M50 will not be meant to be a full-bore M model on the identical stage because the M3 and M4, it’s already nipping on the heels of its gas-powered siblings in our acceleration testing. The electrical i4 M50’s 3.3-second dash to 60 mph beat the rear-wheel-drive M3 Competitors and was solely a half a second behind the all-wheel-drive M4 Competitors xDrive’s outcome. So it goes with out saying that we’re wanting ahead to discovering out what a quad-motor BMW M EV might be succesful.
