Renault Sells Historic Viry-Chatillon Engine Factory to Dumarey Group

Renault has reached an agreement to sell its historic Viry-Chatillon power unit facility to the Belgian engineering firm Dumarey Group. The move aims to preserve approximately 150 specialized jobs and secure the future of the site after Alpine abandoned its 2026 engine project and transitioned to a customer power unit model.

Why it matters:

This transaction represents the final chapter of Renault's identity as a full-blooded works manufacturer in Formula 1. By offloading the facility, Renault is formally decoupling its automotive brand's engineering legacy from its current F1 operations, signaling a strategic pivot toward operational efficiency over technical independence.

The details:

• Scope of Sale: Dumarey Group will acquire Alpine Racing SAS, including its engineering teams and tangible assets. Crucially, the sale does not include any assets belonging to the Alpine F1 team based in Enstone.
• Job Preservation: The deal ensures that roughly 150 employees will transfer to the new owner, maintaining a critical hub of high-performance engineering in France.
• The Legacy: Viry-Chatillon served as the heart of Renault's F1 ambitions for over 40 years, securing 23 championships (12 Constructors', 11 Drivers') and 169 race wins.
• Strategic Shift: The sale follows the September 2024 decision to scrap the 2026 power unit development in favor of a customer supply arrangement with Mercedes.

The big picture:

For decades, the Viry-Chatillon site was a symbol of French motorsport prestige. While Renault initially planned to transform the site into "Hypertech Alpine"—a center for supercars and solid-state batteries—the sale to Dumarey Group shifts the facility's trajectory toward an independent industrial model. Dumarey intends to leverage the site's expertise in hybrid and electric propulsion to expand into broader motorsport and industrial sectors.

What's next:

As Alpine moves forward as a customer team using Mercedes power for the 2026 regulations and beyond, the focus shifts to Dumarey's ability to monetize F1-grade engineering in the private sector. The final completion of the deal remains subject to regulatory approvals and the required consultation process with employee representatives.
