Autonomous driving technology firm Pony.ai and ride-hailing giant Uber have expanded their partnership to deploy thousands of robotaxis across Europe. According to coverage from The Verge, the initiative kicks off in Zagreb, Croatia, in collaboration with Verne, a autonomous vehicle venture spun off from supercar maker Rimac.
Inside the Zagreb Pilot and the Tech Stack Powering Europe’s New Fleet
The initial phase of this European rollout is currently taking shape on the streets of Zagreb. Here is why that matters: the companies are actively validating their software and hardware stack using Pony.ai’s Arcfox Alpha T5 Robotaxi. This specific vehicle runs on Pony.ai’s 7th-generation technology stack and was jointly developed alongside state-owned Beijing Automotive Group Co (BAIC), as detailed in reports from The Verge.
Verne, headquartered in Zagreb, handles the physical management of the local fleet. Meanwhile, Uber contributes its ride-hailing network and customer base to the alliance. Once these validation runs conclude and the partners begin charging standard fares, they anticipate operating Europe’s first commercially available robotaxi service.
Strategic Alignment in the Global Ride-Hailing Market
The company has allied with dozens of autonomous vehicle developers over the past year. But there is a clear motive behind this strategy: shielding its core business model from the financial disruption of autonomous fleets potentially overtaking traditional human-driven ride-hailing.
By partnering with Pony.ai for driving tech, Verne for local fleet oversight, and keeping its own platform as the customer-facing gateway, Uber aims to cement itself as the indispensable aggregator of the autonomous era. According to The Verge, the ultimate goal for this coalition is scaling the active fleet to thousands of vehicles across multiple European markets following the Zagreb launch.
| Partner Entity | Core Responsibility | Key Asset / Vehicle |
|---|---|---|
| Uber | Ride-hailing network and customer acquisition | Global digital platform |
| Pony.ai | Autonomous driving technology development | 7th-generation tech stack / Arcfox Alpha T5 |
| Verne | Fleet management and local operations | Zagreb-based infrastructure (Rimac spin-off) |
What Lies Ahead for European Autonomous Transit
While the immediate focus remains locked on validating vehicles in Croatia, the long-term roadmap envisions a continent-wide expansion.

As deployment scales toward that target of thousands of vehicles, passengers across Europe may soon hail the next generation of driverless transport directly through familiar smartphone applications.
