Representatives of Renault’s Formula 1 engine staff at Viry-Chatillon have called for the French manufacturer to rethink plans for Alpine to become a Mercedes customer – suggesting the decision is a ‘betrayal.’
As part of an effort to improve its fortunes, the Alpine Formula 1 team is poised to commit to becoming a Mercedes customer team from 2026 onwards.
A final decision on the engine plan and the future of its Viry headquarters is expected to take place on 30 September, with a study having already been commissioned by Renault into transferring the focus of F1 personnel at the French factory on to new technology development.

In the lengthy document, the Social and Economic Council outlined how Viry had hit some aggressive development targets with the new engine – which it said had shown good potential during dyno testing.
“More than a hundred disruptive concepts were studied, nearly a third of which demonstrated significant performance on the test bench and should be introduced on the future Alpine engine: the AR26,” it said.
“The target was to start the…
