Alpine's French-based Formula One employees spoke out on Tuesday against the Renault-owned carmaker's decision to cease engine production at the Viry-Chatillon facility at the end of next season.

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.

Renault entered F1 in 1977, introducing the turbo engine to motor racing’s flagship sport and winning five drivers’ titles and six constructors’ crowns.
