Renault confirms selling its Viry-Châtillon engine facility to Belgium’s Dumarey Group, a pivot that follows the shutdown of its in-house Formula 1 power unit project last year.

Dumarey specializes in road-vehicle powertrains and submits a formal proposal to take over the site, collaborating with Alpine Racing to assess operations and financial viability.

The deal includes Alpine Racing SAS and assets required to keep Viry running. The Paris‑suburb base has anchored Renault’s F1 engine efforts for decades.

Job security became uncertain after Renault closed the engine department, particularly as Alpine agreed a customer power unit supply with Mercedes, reducing in-house need.

Alpine also plans to exit the World Endurance Championship after 2024. Viry has supported assembly and maintenance of Mecachrome engines for the A424 LMDh programme.

Endurance implications are immediate. Longtime partner Signatech targets a 2027 continuation under a new brand, though talks with Geely have stalled.

Team principal Philippe Sinault says staff and resources are prepared for the A424 project, but the driver roster remains open following Antonio Felix da Costa’s departure.

Within Formula 1, Renault’s exit from manufacturer engines reflects a shifting power-unit landscape, as new and reworked projects, including Cadillac’s programme, reshape 2026-onwards dynamics.

Dumarey signals intent to expand into motorsport, leveraging Viry’s F1-derived processes and calibration tools to support future competition and advanced road-vehicle applications.

Alpine’s VP of technology, Axel Plasse, frames the sale as a route to sustain know-how, create employee opportunities, and maintain the site’s motorsport relevance under new ownership.

Both parties now accelerate operational reviews to reach swift agreement, protect roles, and chart a viable future that aligns heritage with broader powertrain engineering.
