The BMW Startup Garage and the Munich-based company DeepDrive are set to road-test a revolutionary electric motor. The concept features dual rotor technology and is expected to enable super-efficient, powerful drives that offer plenty of range. After a successful pilot project with promising results on the test rig, the BMW Group and DeepDrive are now planning their first field test. Various versions of the new drive will be installed into BMW Group models and their handling tested out on the road.
DeepDrive’s innovative concept more or less melds two electric motors into a single unit, creating an extremely compact drive that’s energy-efficient and has a high torque density. In a conventional electric motor, the stator moves either an internal or an external rotor; with DeepDrive’s dual rotor concept, the stator drives both rotors simultaneously. The compact design and light weight of the unit allow for an in-wheel drive system, in which each wheel hub has its own electric motor. The technology can also be used in a traditional, centralised drive system, where a central motor block powers the vehicle.
BMW values the maturity level and scalability potential of the DeepDrive innovation.
BMW was the first major manufacturer to discover DeepDrive and has been intensifying collaborations with them since the IAA 2021. Their technology is already remarkably mature: “DeepDrive’s prototype parts largely exceeded our specifications,” says Karol Virsik, Head of Research Vehicle Concepts and Technologies at the BMW Group. “That’s really unusual at such an early stage and with a completely new technology.”
After a stint on the test rig, the proof of concept was deemed successful, delivering top results. The next step is to perform a real-world validation out on the road. The in-wheel motors will require less space and be more energy-efficient, lighter and less costly, making them an attractive option for a wide range of vehicle models and potentially highly scalable. “DeepDrive has developed an exciting vision for the electric drive of the future,” said Virsik. “The Startup Garage allows us to experiment with DeepDrive and work out what drives might look like in the generation after next.”
DeepDrive is now collaborating with other manufacturers and major suppliers as well, such as Continental. In 2024, their motor concept was honoured with the German Innovation Award. “Collaborating with BMW gave us a springboard really early on,” said Felix Pörnbacher, co-founder and co-CEO of DeepDrive. “It helped us navigate the complex corporate world and meet and exceed the rigorous standards of the automotive industry. Our goal now is to get it integrated into a production model.”
