Renault decided to end Formula One engine production after next season for financial reasons but its Alpine team is a "family jewel" and not for sale, chief executive Luca de Meo said on Friday.

The announcement came on Monday, days after Alpine's aggrieved factory staff made a last appeal to Renault CEO Luca de Meo, urging him to reconsider the plan to transition into a customer team in Formula 1. Ultimately, the Renault board reached its final decision on September 30th.

Struggling Formula 1 team Alpine confirmed it will no longer use its homemade Renault engines in 2026. Alpine said in a statement on Monday that its F1 engine factory at Viry-Chatillon on the outskirts of Paris would become an engineering center called Hypertech Alpine, starting from the end of this year.
