Lucid Group Inc., a Nasdaq-traded automaker, will build the vehicles. Venture-backed startup Nuro Inc. is set to provide autonomous driving software for those vehicles. As part of the collaboration, Uber is reportedly investing $300 million in Lucid and an unspecified larger sum in Nuro.

The partnership will combine Uber's ride-sharing platform with Lucid's new electric SUV, the Gravity, and Nuro's autonomous driving technology. It'll be launching first in an unnamed "major US city," but is expected to roll out globally to more than 20,000 Lucid vehicles over the next six years.

Uber will acquire and deploy over 20,000 Lucid Gravity SUVs that will be equipped with autonomous vehicle technology from startup Nuro.
