Cadillac recently announced it’s joining the F1 circus in 2026 but it won’t be powered by a GM engine, at least not initially. The US team has a deal to use Ferrari engines when it lines up for the first time in ‘26, joining as the 11th team on the grid.
This “multi-year agreement” will see Ferrari power units used by Cadillac for at least its first two seasons. Depending on how well GM’s engine development programme goes, Cadillac could use Ferrari engines until at least 2030. This is inline with Cadillac’s initial statement of intent to be a “full works” team — building its own F1 vehicles and power units — by the end of the decade”.
Ferrari power is also used by Sauber and Haas teams. The only other F1 teams making their own chassis and engines currently are Scuderia Ferrari and Mercedes-Benz.
Mercedes-Benz supplied power for the McLaren team in 2024 (which won the constructor’s championship this year ahead of Ferrari) as well as Williams and Aston Martin. From 2026, the German will also power the Alpine team.
Cadillac will be joined by Audi in 2026, the German’s taking over the Sauber team. Ford will be back on the grid then too, set to replace Honda as a powertrain partner for the Red Bull Racing team.
