The BMW M division has begun highway checks of an EV concept with 4 electrical motors. The most recent M automotive idea is predicated on the BMW i4 M50 and options an tailored physique strut idea taken from the M3 and M4. However the typical inline-six cylinder engines of the enduring M vehicles and twin electrical motors of the i4 M50 EV have been changed with 4 electrical motors that ship energy to every particular person wheel.
The 4 electrical motors are managed by a brand new built-in management system, however BMW remains to be referring to the configuration because the M xDrive system. That is smart, on condition that that is, basically, only a purer type of four-wheel drive; that’s why BMW thinks the way forward for the M division and M vehicles, general, will depend on new high-performance electrical motor arrays.
Nevertheless it’s not nearly placing extra energy down as crudely as doable. BMW says it’s paying simply as a lot consideration to dealing with, too. With the brand new management system, the 4 motor M EV idea can ship torque to every wheel quicker and extra exactly than M vehicles with typical drivetrains. BMW says the benefit of getting one electrical motor per wheel infinitely variable torque, including that:
The perfect energy transmission to the highway is calculated inside milliseconds from the values for the accelerator pedal place, steering angle, longitudinal and lateral acceleration, wheel speeds and different parameters. The indicators for this are transmitted simply as rapidly and immediately by way of a multi-plate clutch and differentials to the 4 motors, that are capable of implement them instantly and exactly.

Current EV motors and four-wheel drive systems do much of what BMW is describing, but with four electric motors rather than one or two, control over each driven wheel is that much better. And BMW says the system is just as well-suited for performance driving as for handling adverse road conditions.
BMW also says the four motor EV concept can corner faster even in rain and snow, and that it steers effortlessly while also being less prone to understeer. The concept is equipped with the radiator arrangement of the M3 and M4, but in order to fit the four motors over the front and rear axles, the M division had to widen the wheel arches.
For the most part, this quad-motor configuration is the logical evolution of both fully-electric drivetrains and four-wheel drive systems. This latest M EV is still just a concept for now, but if its wide wheel arches make it to production and BMW can manage to balance that massive grille with a wide stance, then the fully-electric way forward for the M division is shiny, certainly.
