GM, Cadillac, and Andretti gained provisional approval to join F1 after the Las Vegas GP. Its engine supply deal with Ferrari rests on the team receiving official written confirmation. The American team originally planned to use Renault engines before switching to Ferrari.

A Ferrari power unit and gearbox will propel Formula 1 newcomer Cadillac F1 Team for its first two seasons in the sport. Maranello confirmed the multi-year agreement Tuesday morning, putting to rest rumors that Honda was also looking to supply the General Motors works team through the end of the 2027 season.

Ferrari will supply engines to the new Cadillac team if its entry is approved for the 2026 Formula 1 season. The US brand has an agreement in principle with F1 to join the championship from 2026 and to build its own engine "at a later time".
