BMW is testing a four-motor powertrain for future M efficiency EVs, the automaker introduced Wednesday in a press launch.
The automaker has already launched food regimen M Efficiency i4 M50 and iX M60 fashions, however not a devoted electrical M mannequin that pulls out all of the stops. The prototype powertrain—revealed an i4 improvement mule—hints at what may energy the primary of these fashions.
BMW mentioned it is testing each the powertrain and a associated chassis-control system that helps higher distribute energy, the automaker claims. The infinitely variable torque distribution of electrical motors permits numerous flexibility, BMW famous, saying that the system measures output from sensors, as properly steering angle and accelerator strain, to use the optimum quantity of energy.

The i4 M50 improvement mule makes use of some parts from the gasoline BMW M3 and M4 (which share the identical platform) to enhance cooling and torsional rigidity, in addition to to create space for the 4 motors. Two motors energy every axle, that means every wheel will get its personal particular person motor.
BMW’s use of a four-motor powertrain for a efficiency EV is not an environment friendly method; it provides additional weight; and it is pretty novel, as many different producers are maxing out at three motors. Lucid has been creating a tri-motor version of the Air, and Tesla beforehand confirmed the tri-motor Mannequin S Plaid+, though the latter has been effectively cancelled.
The GMC Hummer EV makes use of three motors as properly, which is sufficient to get the roughly 9,000-pound truck from 0-60 mph in 3.0 seconds with “Watts to Freedom” (WTF) mode. And three-motor Audi E-Tron S variations can be found, however they’re uncommon and we’ve not had any alternative to drive them—not to mention go back-to-back with the dual-motor variations.

Rivian gives a quad-motor powertrain within the R1T pickup truck and R1S SUV however hints that the structure is very expensive to build—although it is teased particular Tank Turn and K-Turn modes with it. Tesla has additionally promised a four-motor model of the Cybertruck, whereas the Lordstown Endurance is slated to make use of 4 in-wheel motors.
So if BMW’s quad-motor powertrain makes it to manufacturing in a future M mannequin, exterior of unique supercar makers like Rimac it could possibly be the primary of its type aimed toward canyon roads and racetracks relatively than job websites and off-road trails. Keep tuned.
