Mercedes is the power-unit supplier listed for Alpine in the 2026 season.
The change ends Alpine’s works relationship with Renault. Alpine had inherited Renault’s Formula One operation and continued using Renault power units after the team was rebranded from Renault F1 Team in 2021. Renault ended its factory power-unit programme after the 2025 season, prompting Alpine to become a Mercedes customer from 2026.
Mercedes supplies more than its own factory team. In 2026 its customer network also includes McLaren, Williams and Alpine, giving the German manufacturer one of the broadest power-unit programmes on the grid. Alpine uses Mercedes power units and gearboxes while continuing to design and build its own chassis.
A frequent mistake is to answer Renault because Alpine remains a Renault-owned brand and its Enstone team has a long Renault identity. That ownership history does not determine the 2026 engine supplier: the official entry lists Alpine with Mercedes power.
