Cadillac Registered as F1 Engine Supplier Starting in 2028

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

This comes about a month after the FIA approved Andretti’s Expression of Interest application for Andretti Cadillac to race in the F1 World Championship.

“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.”

Development and testing of prototype power units is already underway, GM says.

Cadillac Racing made headlines earlier this year in both the IMSA WeatherTech SportsCar Championship and FIA World Endurance Championship (WEC) with its 5.5-litre DOHC V8 powertrain. Most notably, it secured a podium finish at the 24 Hours of Le Mans and swept top championship honours for the inaugural IMSA Grand Touring Prototype season.

Andretti, meanwhile, is slated to join the F1 grid as early as 2026. Where will its power units come from until Cadillac is ready?

As Motorsport.com reports, the FIA will allow the team to qualify for an engine supply for 2026 based on current F1 regulations. That means it will have to settle for the engine manufacturer that's supplying the fewest customer teams—likely Honda or Alpine, which are currently committed to just one team each.

Let’s not forget that another American automaker is set to return to F1 for 2026. Ford has teamed up with Red Bull for the development of next-gen power units. Red Bull Ford Powertrains will provide the power units for both the Oracle Red Bull Racing and Scuderia AlphaTauri teams from 2026 to at least 2030.
