Formula One is set to welcome Cadillac as the 11th team on the grid in 2026. But with General Motors entering the sport as a power unit manufacturer by 2028, the two gap years mean the Cadillac F1 car will need to run with a different engine.

Now it’s official, Ferrari will supply power units to the Cadillac F1 team for two seasons before the GM team finishes its own package.

According to the statement, “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."

Ferrari’s move to supply Cadillac sees Maranello provide engines for two American F1 teams for 2026. Haas remains in close ties despite its technical partnership with Toyota Gazoo Racing, while Ferrari’s power unit deal with Sauber expires next year as the latter moves forward as an Audi works team.

Previously, Cadillac struck a deal with Renault under the previous Andretti Cadillac entry. But with the change of management at Andretti Global and Renault’s decision to cease its operations as an F1 power unit supplier, this led Cadillac to strike a deal with Ferrari.

Along with the engine deal, GM and TWG Global has announced Graeme Lowdon will be the team principal for the Cadillac F1 project. Lowdon ran the Manor/Marussia/Virgin team in F1 from 2010 to 2015, and recently played a part in the management of Zhou Guanyu – China’s first full-time F1 driver.

Furthermore, other notable names in the Cadillac F1 project include former Renault Technical Director Nick Chester and former Renault operations chief Rob White.
