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.

Renault will end its Formula 1 engine programme after the 2025 season, the French car company has announced. The decision means Renault's Alpine team will have to buy engines from another manufacturer, which is expected to be Mercedes, from 2026.

Renault will close its independent Formula 1 engine program after the 2025 season, marking the end of an operation that has built championship-winning engines on and off since the 1970s. The Alpine Formula 1 team will continue, the team says, but with a customer engine deal when a new generation of series regulations begin in 2026.
