BMW is creating a four-motor prototype primarily based on the i4 M50 four-door coupé to provide the automobile the full-fledged M division remedy, which is able to make use of its one-motor-per-wheel powertrain to use infinitely variable, extraordinarily exact and really fast distribution of drive torque, says the automaker.
Right here, the event automobile will be seen to used the entrance fascia of the G80 M3/G82 M4, and its entrance finish employs the physique strut structure tailored from the aforementioned M fashions to make sure particularly excessive torsional rigidity for “extraordinarily dynamic driving conditions.” The radiator structure on this growth EV can be primarily based on that of the model’s present high-performance fashions, it says.
The throttle load demand from the accelerator pedal will be signalled to every motor inside milliseconds, and at a degree of precision that might in any other case be “unattainable utilizing typical drive programs,” says BMW.
A extremely built-in management unit continually displays the driving circumstances, retaining tabs on parameters corresponding to throttle place, steering angle, longitudinal and lateral acceleration, wheel speeds and extra, and the management unit calculates the perfect output transmission inside milliseconds.
Alerts are then transmitted to every of the 4 motors by way of a multi-plate clutch and differentials, that are capable of execute the outputs instantly and exactly, BMW says. Every of the 4 motors can even operate as a generator for power recuperation when decelerating, thus feeding electrical energy again to the automobile’s high-voltage battery.
Among the many benefits of the powertrain’s fast responses are considerably greater cornering speeds, even on rain-soaked or snow-covered roads, says BMW. Additionally apparently doable with the four-motor configuration is a tank-turn burnout, in response to footage inside a video launched by BMW M.
The i4 M50 that the four-motor M prototype is being developed from was unveiled in June final yr, using one motor on every axle. Mixed and with the Sport Enhance operate, peak energy and torque is 544 PS and 795 Nm, enabling a 0-100 km/h time of three.9 seconds and a prime pace of 225 km/h. The i4 M50 arrived in Malaysia in May this year, priced from RM430,800 at launch.
