We already knew General Motors was looking to get a foot into the door of Formula One, using Cadillac in a bid with Andretti to become the sport’s eleventh team from as early as 2025. That’s yet to go through, but GM has signalled its intent to build engines for the team.
The American giant confirmed today it had registered with the FIA to produce Cadillac-branded power units from the 2028 season, with development already underway. With the current Formula One engine regs in place since 2014, bar a few tweaks here and there, it makes sense for GM to hold off a few years.
"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." - Mark Reuss, General Motors president
2026 will see the current 1.6-litre turbocharged hybrid V6 engines evolve to draw more power from its MGU-K and run on fully sustainable fuels, giving its engineers a chance to focus on the new ruleset rather than rush to join alongside Andretti’s planned debut.
Mark Reuss, General Motors president, 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.”
Andretti had originally planned to use Renault engines on its Formula One debut, though it reported a pre-contract agreement between the two expired in October and that talks had not resumed. FIA President Mohammed Ben Sulayem said the team would not be left without an engine supplier should its application to join the sport go through, but who that will be remains to be seen.
GM will be the latest in a flurry of suppliers joining the sport. Ford is working with Red Bull on a technical partnership that will see its branding on the team’s engines from 2026, while Honda has confirmed a formal return to supply Aston Martin in the same year. Audi is set to take over Alfa Romeo Sauber then, too, bringing its own engines in the process.
