Details are sparse, but the companies highlighted that the road-tests follow a successful pilot project. Various versions of this innovative drive unit will be installed in BMW Group models. The dual rotor technology effectively combines two electric motors into one compact unit, enhancing energy efficiency and torque density. Unlike conventional motors where the stator drives either an internal or external rotor, DeepDrive’s stator drives both rotors simultaneously.
BMW emphasized that the motor’s compact design and light weight enable an in-wheel drive system, with each wheel hub housing its own motor. This technology can also be applied to a traditional centralized drive system, where a central motor powers the vehicle.
The in-wheel motors are touted to save space, be more energy-efficient, lighter, and less costly, making them an attractive and scalable option for various vehicle models. This potential is promising, but practical outcomes remain to be seen.
Recently, spy photographers captured images of a Neue Klasse coupe, expected to preview a low-volume sports car, possibly equipped with DeepDrive motors. Observers noted the absence of brake calipers and the presence of "silver wheel hub motors" visible behind the black wheels, suggesting the use of DeepDrive’s technology.
