General Motors registers as power-unit supplier for F1 2028 season

American car giants General Motors have officially registered as a Formula One power-unit supplier starting from the F1 2028 season. GM stated that they plan to supply Andretti Cadillac as a full works team. This would see them become the 11th team on the grid.

Andretti has already received FIA approval to join the grid but is awaiting for a clearance from Formula One Management (FOM), with most of the teams, who are already on the grid generally being against Andretti joining the grid. Andretti was reported to be in contact with Renault as their engine supplier for their entry in 2025 but Renault and Andretti are no longer going ahead together. 

Reports suggest that General Motors and Andretti executives are going to attend this weekend’s Las Vegas Grand Prix 2023 to try and sway the FOM in their favour. 

GM also revealed that ‘engineering a F1 power unit will advance GM’s expertise in areas including electrification, hybrid technology, sustainable fuels, high efficiency internal combustion engines, advanced controls, and software systems.’ GM also spoke about the positive feedback from developing the 5.5L DOHC V8 powertrain which was used this year at the IMSA and WEC championships.

Mark Reuss, President, General Motors, said,

“We are thrilled that our new Andretti Cadillac F1 entry will be powered by a GM power unit. With our deep engineering and racing expertise, we’re confident we’ll develop a successful power unit for the series, and position Andretti Cadillac as a true works team. We will run with the very best, at the highest levels, with passion and integrity that will help elevate the sport for race fans around the world.”

The Formula One PU regulations are set to change from the 2026 season and the six currently registered manufacturers (Audi, Alpine, Ferrari, Honda, Mercedes and Red Bull Ford) will see an addition with General Motors joining as the seventh.
