Cadillac to use own F1 power units from 2029, FIA confirms

General Motors will enter Formula 1 as a power unit manufacturer in 2029, the FIA has announced.

The US car making giant will join the championship with its own team, Cadillac, next year. It has already agreed a deal to use power units supplied by Ferrari.

GM previously confirmed it had begun work on a power unit for F1’s new regulations which will come into force next year, but had not set a date for its introduction.

The sport’s governing body has now confirmed GM will introduce its power unit in the fourth year after F1’s next engine formula is introduced.

“Welcoming GM Performance Power Units LLC as an approved power unit supplier for the championship starting in 2029 marks another step in the global expansion of Formula 1 and highlights the growing interest from world-class automotive manufacturers like General Motors,” said FIA president Mohammed Ben Sulayem.

“Their dedication to innovation, sustainability, and competition is fully aligned with the FIA’s vision for the future of our sport. It also strengthens our commitment to making motorsport more accessible and inclusive worldwide—welcoming new manufacturers, advancing technology, and connecting with a broader, more diverse fan base.”

The development of GM’s F1 power unit is being steered by Russ O’Blenes (pictured), CEO of GM Performance Power Units. The company is due to move into a new building to begin construction of its F1 power unit in 2027.

Ben Sulayem recently cast doubt over the future of F1’s new engine regulations after stating the sport should consider switching to normally aspirated V10 engines. A meeting between the FIA, Formula One management and engine manufacturers two weeks ago in Bahrain resulted in a commitment to the planned rules cycle, meaning the incoming hybrids are expected to remain in use until at least 2030.
