Sources: 17. Developments: 2. Renault has reached an agreement to sell its historic Alpine Racing SAS facility in Viry-Châtillon to the Belgian Dumarey Group. The sale follows Renault’s decision to end its in-house Formula 1 engine development program in favor of a customer model using Mercedes power units. The acquisition includes the transfer of approximately 150 employees and all essential assets required to operate the research and development site independently. While financial terms remain undisclosed, Renault has committed to a transition that includes guaranteeing social benefits and salaries for 24 months. Guido Dumarey, chairman of the Dumarey Group, intends to leverage the site’s expertise in high-performance powertrains, electrification, and advanced testing technologies. The move follows Renault’s strategic shift to reduce costs and focus on more profitable business areas, coinciding with Alpine’s planned departure from the World Endurance Championship (WEC) at the end of the year. ## Timeline ### 2026-10-24: Renault sells Viry-Châtillon engine factory to Dumarey Group Renault is selling its historic Viry-Châtillon engine factory to Belgium's Dumarey Group as it shifts focus toward more profitable sectors and utilizes customer engines for Alpine F1. 3 sources. https://clstr.news/cluster/renault-sells-viry-chtillon-engine-factory-to-dumarey-group ### 2026-10-22: Dumarey Group to acquire Renault's Alpine Racing facility Renault is selling its historic Viry-Châtillon F1 engine facility, Alpine Racing SAS, to the Belgian Dumarey Group, preserving approximately 150 jobs and the site's technical expertise. 14 sources. https://clstr.news/cluster/dumarey-group-acquires-alpine-racings-f1-engine-facility --- Cite as: Renault sale of Alpine Racing facility to Dumarey Group.
