GUANGZHOU — Two years after Pony.ai first announced a global robotaxi partnership with Uber, the two companies said Thursday they are ready to scale it. More than 2,000 autonomous vehicles will be deployed across four European cities under an expanded collaboration, the largest robotaxi commitment Europe has seen in a single announcement, and a test of whether a Chinese autonomous vehicle company can operate commercially in a market that has no comparable history with the technology.
The deal’s structure is deliberate: Pony.ai supplies the Level 4 autonomous driving system, Uber provides the booking platform and rider access, and a local partner in each city manages the fleet’s maintenance, charging, and day-to-day operations. The three-way division of responsibility is what Pony.ai calls its “joint-deployment model,” developed over the course of its European entry through Zagreb, Croatia, where it launched the continent’s first commercial robotaxi service earlier this year with Croatian mobility company Verne.
Zagreb was the proof of concept. The four cities to follow, not yet named, are the scaling test.
“This expanded agreement marks an important new phase in the partnership between Pony.ai and Uber,” James Peng, Pony.ai’s founder and chief executive, said in the announcement. Sarfraz Maredia, Uber’s global head of autonomous mobility, was more specific about what the new phase is meant to prove: “The next chapter for autonomous mobility is about moving from individual launches to repeatable commercial scale.”
The distinction between the two statements is instructive. Peng’s framing is about the partnership. Maredia’s framing is about whether the deployment model, combining Pony.ai’s autonomous technology, Uber’s platform, and local fleet operators, can be replicated across markets in a way that does not require starting from scratch in each city.
What the announcement does not provide: a timeline, a deployment schedule, or the names of the four cities. The companies said details would be “revealed in phases,” a formulation that suggests a staggered rollout contingent on local regulatory approvals rather than a fixed commercial launch date. European autonomous vehicle regulation varies substantially by member state; Pony.ai’s Zagreb launch required Croatian regulatory clearance that does not automatically transfer to Germany, France, or anywhere else.
Pony.ai operates fully driverless paid services in four Chinese tier-one cities and, according to TechCrunch, has reported achieving what it calls “city-wide breakeven economics,” the point at which ride revenue covers the cost of operating each vehicle without subsidy. The company’s Gen-7 robotaxi fleet, which uses ARCFOX Alpha T5 and Toyota bZ4X variants with its proprietary autonomous driving kit, has accumulated operating hours in China that are difficult for any European or American competitor to match. That operational depth is what Uber is buying into.
Pony.ai went public on the Nasdaq in late 2024, and the European expansion is its most visible statement of growth since that listing. The company has logged more than 40 million autonomous miles across its global fleet, including its fully driverless paid services in Guangzhou, Beijing, Shanghai, and Shenzhen. Arriving in Europe with that operational record allows Pony.ai to frame the Zagreb launch, and the four cities that follow, not as experiments but as the geographic expansion of a system already running commercially in some of the world’s most demanding urban environments.
The Middle East is also part of the expanded partnership. Pony.ai has been operating in Qatar for several years, and the new agreement extends the collaboration to additional markets there as well, though again without specifying which ones.
Uber’s position in this arrangement is essentially a distribution play. The company has partnerships with more than 30 autonomous vehicle companies, according to its own filings, and has structured each as a means of integrating AV fleets into its platform without owning the technology or the vehicles. Uber and Waymo have been lobbying together for national robotaxi regulations in Washington, a shared interest in creating a clearer federal framework, even as the two companies compete on the same streets in some US markets.
What Pony.ai brings to the arrangement that Waymo cannot is Chinese manufacturing and supply chain economics. The Gen-7 system’s bill-of-materials costs have been cut by 70% over successive versions, and Pony.ai has said total vehicle costs in China will fall below RMB 230,000 by 2027. The European expansion will require hardware certified for European Union regulations, which adds cost, but the starting point is substantially lower than what US-developed autonomous vehicle systems currently require per unit.
The robotaxi sector’s safety record continues to generate scrutiny, and European regulators will be watching Pony.ai’s Zagreb operations closely before approving broader deployment. Zoox’s fourth recall in 16 months, for failure under wildfire smoke conditions, has renewed focus on edge-case performance. Pony.ai has not disclosed whether its Gen-7 system has a comparable operational limitation profile for the European climate and road conditions where it now plans to expand.
Neither Uber nor Pony.ai specified which European cities are being targeted, or whether any city governments have been approached for the necessary authorizations.
