General Motors has announced it has formally registered as a Formula 1 power unit manufacturer starting from 2028, and plans to supply Andretti Cadillac as a full works team.
Andretti Cadillac’s entry has been approved by the FIA but still needs to reach a commercial agreement with Formula One Management (FOM) to be able to join the grid, and has faced opposition from existing teams. After recently reiterating that it was only interesting in partnering with Andretti, GM has now made the major announcement that it will provide a full power unit to the Andretti Cadillac team as an F1 supplier.
“We are thrilled that our new Andretti Cadillac F1 entry will be powered by a GM power unit,” GM President Mark Reuss said. “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.”

F1’s power unit regulations are set to change in 2026, and there are currently six manufacturers registered with the FIA including Alpine, Audi, Ferrari, Honda, Mercedes and Red Bull Ford. GM would become the seventh manufacturer from 2028 onwards.
GM states 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,” while highlighting its recent success developing the 5.5-liter DOHC V8 powertrain that was used in this year’s IMSA and WEC championships.
