After Renault’s Alpine announced the decision to cease making engines for F1 race cars after 2025, that left open the question of where Alpine’s F1 team would turn to source their engines. We now know the answer. Beginning in the 2026 season, Mercedes will supply the power units for Alpine’s F1 race car. Mercedes will also supply the gearboxes used in the cars in 2026. The agreement to use Mercedes power units lasts through 2030, but Alpine plans to build and use their own gearbox starting in 2027.
Why Alpine’s decision is a big deal
When Alpine disclosed it would cease building engines for F1 cars, it was a sea change for the manufacturer. Alpine and parent company Renault have historically been engine suppliers, providing engines to their F1 team and other teams. With the new agreement, Alpine will be power unit customers, no longer potential suppliers to other teams.
What the power unit supply deal means
The 2025 season will be the last season for the current power units. In 2026, F1 race cars and power units will be subject to next-generation FIA F1 rules and regulations. The new power units will have internal combustion engines that run on 100% biofuels and will use battery power more than the current power units.
Alpine will continue to build F1 engines at its Viry-Chatillon, France division through the end of the 2025 season, after which it will be re-purposed to Hypertech Alpine. Alpine’s Enstone, UK division will continue to focus on the F1 race car’s chassis.
The Alpine website issued a brief statement, “The multi-year agreement will see Mercedes-Benz supply BWT Alpine Formula One Team with Power Units for the duration of the new regulation era, from 2026 until at least 2030. Alongside the Power Unit, BWT Alpine Formula One Team will also be supplied with Mercedes gearboxes from the 2026 season.“
