Ferrari has announced a "multi-year agreement" with Andretti Formula Racing to supply power units to the Cadillac Formula 1 entry upon its debut in the championship in 2026.
The team, led by TWG Global—which recently took over the management of Andretti Global—and General Motors, was provisionally accepted onto the grid for 2026 by F1 last month, though full confirmation is still pending.
GM will run the team under the Cadillac brand. As part of the previous Andretti-named project, which was rejected as the 11th team in earlier attempts, GM announced its intention to manufacture its own power unit for racing. However, the target date for this is 2028, necessitating an interim power supply for the initial two years of racing. A statement from Ferrari read: "Ferrari N.V. today announces a multi-year agreement starting from 2026 with Andretti Formula Racing LLC, regarding the supply of power unit and gearbox to the racing team led by TWG Global and General Motors, subject to Andretti Formula Racing LLC receiving written confirmation from the FIA – F1 that its entry to the 2026 FIA Formula One Championship has been accepted and approved."
Last week, GM and TWG Global announced former Virgin/Marussia/Manor boss Graeme Lowdon as the team principal for the project, to help guide the upstart through its initial development. The move to supply Cadillac will see Ferrari return to having two customer teams from 2026, with Haas maintaining close ties. Sauber, currently powered by Ferrari, will switch to Audi power when it becomes the German marque's works team.
Ferrari team principal Fred Vasseur added: "It's great to see the commitment of another American team, backed by one of the most highly respected marques in the motor industry, at a time when Formula 1 is increasing in popularity in the United States.
"We are delighted, therefore, that we will be supplying the team with our power unit and gearbox as the basis of this technical collaboration. It means we will continue to have two 'customer teams' in the championship with all the benefits this brings in terms of technical development within Ferrari."
Board director and 1978 world champion Mario Andretti had revealed that a deal was struck with Renault under the team's previous guise. However, the situation changed due to the management shift at Andretti Global and the decision by the French manufacturer to cease its power supply in the championship, opting instead to switch its Alpine team to Mercedes power.
