BMW M Quad-Motor EVs to use radical “Hand of God” ECU


BMW M performance EVs to use radical 4WD technology

First details emerge of highly advanced ‘hand of God’ system for quad-motor sporting EVs…4wd-technology


Speaking exclusively to Autocar following the recent unveiling of the new BMW M2 Coup, which is in line to receive similar technology in its next generation, M CEO Frank van Meel hinted that 4WD performance EVs will take the lead from the F90-generation BMW M5 xDrive saloon. That model was controversial on its reveal for adopting a powered front axle but now regarded as one of the best-handling sports saloons of its time.

“The secret behind that,” he said, “is that you have a central controller, or a central logic that controls everything: the rear differential but also the front-to-rear differential and the DCS [Dynamic Stability Control] system.”

Having one system that manages these relationships is crucial because “if you have four systems that try to co-operate, the car drives like a car with four systems that like to co-operate”.

BMW calls this ECU the ‘Hand of God’. It has developed it for deployment on various M cars since it first appeared on the BMW i8 as a means of balancing the output of its petrol and electric powerplants and allowing for advanced torque vectoring to improve handling.

“If you go a step further and look at electric cars with four electric motors, like we have in our very early development car, then of course you can still use the same logic to control the car that drives like an M,” said van Meel. “So I’d say it gives you even more possibilities.”
