In a move that signals the robotaxi race is becoming a multi-lane pile-up, Uber Technologies, Inc. is pumping up to $1.25 billion (£1 billion) into Rivian Automotive, Inc. to build out a massive autonomous vehicle fleet. The deal kicks off with an initial deployment of 10,000 fully autonomous Rivian R2 SUVs, with Uber and its partners holding an option to snap up a further 40,000 units—potentially bringing the total fleet to a staggering 50,000 vehicles.
The first wave of these driverless Rivians is slated to hit the tarmac in San Francisco and Miami starting in 2028. From there, the plan is to scale up rapidly, targeting 25 cities across the United States, Canada, and Europe by the end of 2031. It’s an aggressive roadmap that forms the backbone of Uber’s strategy to reinvent itself as the ultimate platform for autonomous mobility, effectively turning a potential existential threat into its new bread and butter.
This isn’t Uber’s only iron in the fire. The company has been busy assembling a “who’s who” of autonomous partners, including an ongoing service with Motional (a Hyundai subsidiary) in Las Vegas and a fresh deal to bring Zoox (Amazon’s self-driving arm) into the fold in Vegas and Los Angeles. By hedging its bets across multiple developers, Uber is positioning itself as the central, brand-agnostic marketplace for the robotaxi era.
Under the bonnet, the Rivian R2s will be powered by the firm’s third-generation autonomy platform. This isn’t just off-the-shelf kit; it’s a vertically integrated system boasting a formidable sensor suite of 11 cameras, five radars, and a LiDAR unit. The real heavy lifting, however, is handled by a pair of custom-designed Rivian Autonomy Processor (RAP1) chips. Together, they provide a massive 1600 TOPS of AI compute performance—plenty of “brainpower” to navigate the chaotic streets of a major city.
Why does this matter?
This partnership is a direct shot across the bows for the likes of Waymo and Tesla, proving that the hardware and network scaling required for a robotaxi revolution is moving into top gear. For Uber, it’s about diversifying its portfolio and cementing its role as a platform provider rather than a hardware developer—a lesson learned the hard way after offloading its own eye-wateringly expensive self-driving division years ago.
For Rivian, this is a massive vote of confidence and a guaranteed, large-scale commercial order that provides a clear path to scaling production and its in-house autonomy stack. With a target annual capacity of 155,000 R2 units at its Illinois plant, fulfilling Uber’s order is a tall order, but a manageable one. For the rest of us, it means the sci-fi dream of hailing a car with no one behind the wheel is rapidly becoming a daily reality. The race is well and truly on.
