Autonomous trucking company Aurora is acquiring Uber Technologies Inc.’s self-driving unit, Advanced Technologies Group (Uber ATG). ATG’s team and technology will accelerate Aurora’s mission and the delivery of its first product, the company said.

In addition to acquiring ATG, Aurora is also announcing a strategic partnership with Uber that connects its technology to the leading ride-hailing platform and strengthens its position to deliver the Aurora Driver broadly.

While autonomous trucking is where Aurora will deliver a product first, the relationship with Uber puts Aurora in the unique position to be a leading player in both autonomous trucking and passenger mobility. In support of Aurora’s partnership with Uber, Uber is investing $400 million in Aurora and Dara Khosrowshahi, the CEO of Uber, is joining Aurora’s board of directors.
