Two years ago, FCA said it would produce about 100 Chrysler Pacifica Hybrid minivans integrated with Waymo’s suite of self-driving hardware and software. Waymo uses these self-driving minivans for testing as well as for its Waymo One autonomous ride-hailing business in the Phoenix area. The autonomous vehicles used in the Waymo One service still have a human safety driver behind the wheel.

FCA and Waymo expanded on their relationship in 2018, with FCA announcing it would supply Waymo with up to 62,000 more Chrysler Pacifica minivans.

Unlike Waymo, Aurora has never indicated plans publicly to launch a robotaxi service. Instead, it’s focused on supplying and then integrating its full self-driving stack to companies hoping to deploy autonomous vehicles or services.

Aurora, founded in early 2017 by Sterling Anderson, Drew Bagnell and Chris Urmson, has integrated its technology into six vehicle platforms, including sedans, SUVs, minivans, a large commercial vehicle and a Class 8 truck.

Aurora is just a few months removed from announcing its hefty $530 million Series B round that was led by Sequoia Capital and included “significant investment” from Amazon and T. Rowe Price Associates. The round pushed Aurora’s valuation to more than $2.5 billion. Aurora announced a $90 million Series A round last February from Greylock Partners and Index Ventures, bringing its total raised to date to more than $620 million.
