General Motors today announced that it has formally registered with the FIA as a Formula 1 power unit manufacturer starting in the 2028 season.

“We are thrilled that our new Andretti Cadillac F1 entry will be powered by a GM power unit,” said GM President Mark Reuss. “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.”

Last month, the FIA approved Andretti’s Expression of Interest application for Andretti Cadillac to race in the FIA Formula One World Championship.

GM’s development and testing of prototype technology is already underway. The company said 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.

Cadillac most recently developed the 5.5L DOHC V-8 powertrain used in the 2023 IMSA and WEC seasons. With this powertrain, Cadillac Racing secured a podium finish at the 24 Hours of Le Mans and swept top championship honors for the inaugural IMSA Grand Touring Prototype season.
