Alpine is contemplating a significant shift in 2026, possibly moving from Renault engines to becoming a customer team. This potential change brings a host of considerations, especially regarding Formula 1’s engine supply rules.
If Alpine decides to discontinue Renault engines, they’ll need to secure a new supply, which isn’t straightforward given how teams’ plans are already set. Fortunately, F1’s rules guarantee Alpine an engine deal by May 15, 2025, if they haven’t secured one by themselves.
The technical regulations for 2026 stipulate the minimum number of teams a manufacturer must supply. This is calculated with a specific formula. If Renault exits, leaving five manufacturers (Audi, Ferrari, Mercedes, Honda, and Red Bull), the formula determines that each manufacturer must be ready to supply up to three teams.
Currently, Mercedes is the only manufacturer meeting this requirement for 2026, by supplying its own team, McLaren, and Williams. The regulations prioritize manufacturers supplying the fewest teams. Thus, Audi and Honda, each supplying one team, would be next in line to provide engines. However, a clause exempts new manufacturers, which means Audi wouldn’t be obligated, leaving Honda responsible for striking a deal alongside their existing arrangement with Aston Martin.
Alpine’s situation could become more complex as Mercedes might step in to supply them if they choose to, despite already being at maximum capacity according to the current rules.
The future engine regulations also limit the number of teams a manufacturer can supply. For 2026, if Renault stays, the maximum a manufacturer can supply is calculated as three teams. Should Renault exit, the figure rises to four, allowing Mercedes to expand their supply if they wish.
The spotlight is now on Alpine and Renault, as both weigh their options from financial and competitive perspectives. Their decision will significantly impact the dynamics of the 2026 season.
Alpine’s potential shift from Renault engines to becoming a customer team in 2026 is intertwined with detailed F1 regulations. As the team navigates its options, the outcome will be closely watched by fans and competitors alike.
