Renault Group finalizes sale of Alpine Racing SAS, Viry-Châtillon engine headquarters near Paris, to Belgian powertrain specialist Dumarey Group. The move ends French ownership of Renault’s F1 engine base.

About 150 jobs remain at Viry-Châtillon under the deal, preserving decades of power‑unit expertise. Financial terms stay undisclosed, but both sides commit to continued development at the site.

From 2026, Alpine will run Mercedes customer power units, closing Renault’s direct F1 powertrain programme. That dovetails with new engine rules and a market tilt toward specialist suppliers.

Chairman Guido Dumarey positions the acquisition as protection of Viry‑Châtillon’s intellectual capital. The intention is to maintain operations, develop new projects, and potentially broaden motorsport engagements.

Under Dumarey, the site could supply engineering services to other Formula 1 teams, echoing dynamics highlighted by Audi’s expansion into F1 operations.

Alpine’s Mercedes supply should deliver proven reliability and performance. The trade‑off shifts focus to integration, packaging, and cooling, where chassis efficiency and software calibration determine competitive upside.

Renault’s divestment frees resources for road‑car programmes while Alpine refines its sporting and commercial strategy, including initiatives such as the Adobe–Alpine deal among others.

Consolidation also recognises 2026 power‑unit complexity. Even major programmes face risk, as illustrated by Audi’s engine challenges, making independent expertise increasingly attractive to teams.

Completion is expected shortly, after which Viry‑Châtillon operates fully under Dumarey ownership. The site remains a landmark of F1 powertrains and a platform for ongoing engine innovation work.
