BMW to road-test in-wheel motor from startup DeepDrive

MUNICH: 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 has been working with DeepDrive since the IAA 2021.

BMW said the DeepDrive technology is remarkably mature.


“DeepDrive’s prototype parts largely exceeded our specifications,” said 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 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.

The BMW Startup Garage operates as a venture client, implementing groundbreaking technologies developed by startups and enhancing the BMW Group’s capabilities in innovation, sustainability and operational performance.

The venture client model was established in 2015, with BMW acting as a customer and working closely with young companies to develop their technologies. “The BMW Startup Garage is an excellent opportunity to connect with startups. We then carry on working with the best of them,” said Virsik.

“Startups are really important to us because they think unconventionally and out-of-the-box. They give us new perspectives.”
