Métropole du Grand Paris, Bolt and Stellantis plan a 2028 autonomous-vehicle pilot in as many as five municipalities, testing whether the vehicles can improve connections across the metropolitan region.
The first locations are planned for northwestern Greater Paris. The partners have a longer-range goal of reaching around 30 municipalities; their target for commercial operations is 2030, subject to required approvals. The initiative, called the Greater Paris Autonomous Driving Living Lab, covers a region the partners describe as having 7.2 million residents. Métropole du Grand Paris represents Paris and 129 surrounding municipalities.
The metropolitan authority will coordinate with local governments and oversee the project’s evaluation. Bolt Autonomous Driving Solutions is assigned to plan how the service could fit into local transport and prepare for deployment. Stellantis will supply vehicles based on its L4-Ready Platforms.
The partners are considering uses that would complement public and private transport, including connections to and from transit, access to employment centers, off-peak travel and trips to major events. An independent evaluation of the initial deployment is planned. It will cover operational safety, service quality and user acceptance, transit integration, social and environmental effects, and economic and operating conditions.
Pony.ai is a potential provider of the driving technology, rather than a confirmed selection. The proposed system would use NVIDIA Hyperion and the NVIDIA Halos safety system.
The partners said they submitted the proposal to the European Commission’s Autonomous Drive Ambition Cities (ADACities) initiative, which launched in June 2026 to support autonomous-driving projects in EU cities. Their announcement describes a submission and does not report a selection decision.
The local pilot builds on a broader European partnership between Stellantis and Bolt announced in December 2025. At the time, the companies said they expected trials in European countries to begin from 2026 and set an initial production target for 2029.
The next identified steps are to select routes with participating municipalities and authorities and obtain the necessary approvals.
