Estonian mobility platform Bolt, Chinese-American autonomous driving company Pony.ai and global automaker Stellantis have launched an autonomous vehicle testing programme in Luxembourg, marking Bolt's first foray into autonomous mobility and Stellantis's latest expansion of its Level 4 partner ecosystem in Europe.
How the pilot is structured
The three-way pilot will validate the safety, performance and regulatory readiness of Pony.ai's seventh-generation (Gen-7) autonomous vehicles operating in live city traffic in Luxembourg. Stellantis will supply a midsize van built on its Level 4 (L4)-Ready Platform, Bolt will contribute its ride-hailing platform and marketplace, and Pony.ai will provide the autonomous driving stack and operational experience. The partners describe the project as a "living lab" that will iterate on vehicle deployment, fleet operations, regulatory coordination and platform integration before scaling.
Why Luxembourg
Luxembourg has been chosen for its combination of a dense urban core and a regulatory environment that has been quick to accommodate Level 4 testing. Bolt founder and CEO Markus Villig described the deal as central to Bolt's ambition to become Europe's leading independent ride-hailing platform in the autonomous era, while Stellantis chief engineering and technology officer Ned Curic said the company is designing its L4-Ready Platforms to plug into multiple AV stacks and vehicle segments.
How it fits into Stellantis and Pony.ai's strategy
The Luxembourg pilot deepens an already extensive Stellantis-Pony.ai relationship, building on a 2025 agreement to pilot autonomous vehicles in Europe and on Stellantis's broader L4 alliance with Nvidia, Uber and Foxconn. For Pony.ai, the deal extends a string of recent commercial wins; the company recently reported Q1 2026 revenue up 145% year-on-year as it raised its robotaxi fleet target to more than 3,500 vehicles. In parallel, rival WeRide is preparing to launch Spain's first commercial robotaxi service in Madrid with Uber.
What success looks like
The trio aim to achieve driverless operational readiness before the programme concludes. Achieving that bar in Luxembourg would give Bolt a defensible European foothold against U.S. and Chinese platform giants, while giving Stellantis a working showcase for its L4-Ready vehicle architecture as it courts more AV technology partners.
