The new Cadillac team will join the grid from the 2026 season after the General Motors-backed entry was approved by the FIA and F1.

The confirmation of the entry of American car giant GM’s luxury brand into the sport means the Formula 1 grid will expand to 11 teams from next year.

It was announced last November that Cadillac had secured an agreement in principle to join the grid as part of a revised offering from GM in conjunction with US group TWG Motorsports, which sees General Motors committed to running its own works engine by the end of the decade.

Before its work engine is ready to use, the Cadillac team has secured a deal to initially run Ferrari’s engine and gearbox from its first season in a deal announced in December.

GM has set up its own engine company to develop its first F1 power unit.

A short joint statement read: “The FIA and Formula 1 can confirm that, following the completion of their respective sporting, technical and commercial assessments, the application by General Motors and TWG Motorsports to bring a Cadillac team to the FIA Formula One World Championship from 2026 has been approved.

F1 president Stefano Domenicali said: “As we said in November, the commitment by General Motors to bring a Cadillac team to Formula 1 was an important and positive demonstration of the evolution of our sport.
