General Motors is set to make a historic entry into Formula One as an official power unit supplier starting in the 2029 season, the FIA (Fédération Internationale de l’Automobile) confirmed on Wednesday. The announcement marks a major milestone in the American automotive giant’s growing commitment to global motorsports, with GM Performance Power Units set to power the Cadillac F1 team.
The newly formed GM Performance Power Units division is a collaboration between TWG Motorsports and General Motors. This initiative will supply engines to the Cadillac Formula One team, which will debut next year as the sport’s 11th constructor on the starting grid. Until the GM-built engines are ready, Cadillac will use Ferrari power units.
“With this approval from the FIA, we will continue to accelerate our efforts to bring an American-built F1 power unit to the grid,” said Russ O’Blenes, CEO of GM Performance Power Units. “We’re building a foundation for long-term success in the world’s most prestigious racing series.”
A New Engine Era Ahead
GM plans to open a dedicated engine development facility near Charlotte, North Carolina, by 2026 — aligning with the introduction of new Formula One engine regulations. Starting in 2026, F1 power units will feature a 50/50 split between combustion engines and electric power, reflecting the sport’s push for sustainability and innovation.
While these regulations are slated to run through 2030, FIA President Mohammed Ben Sulayem has floated the idea of reintroducing naturally aspirated V8 or V10 engines — using fully sustainable fuel — as early as 2029. This timing aligns with GM’s planned entry, suggesting the company could be positioning itself to capitalize on a potential shift in regulations.
Growing American Influence in F1
General Motors’ move follows a wave of American investment and interest in Formula One, fueled by the sport’s growing popularity in the U.S., Netflix’s Drive to Survive series, and the addition of multiple U.S.-based Grand Prix races.
The Cadillac F1 project represents the most significant American manufacturer involvement in F1 since Ford’s Cosworth era. If successful, GM could become a powerful challenger to current engine suppliers like Mercedes, Ferrari, Honda, and Red Bull Powertrains.
Debate Over 2026 Power Units
While the FIA confirmed teams remain committed to the 2026 regulations, concerns have emerged over electric deployment on high-speed circuits. A Formula One Commission meeting this week will discuss potential tweaks, such as limiting electric power during races while maintaining it for qualifying.
Mercedes team boss Toto Wolff expressed frustration at the ongoing regulatory debates, calling them “a joke” during a recent interview. In contrast, McLaren’s Andrea Stella emphasized the importance of maintaining open dialogue to ensure the sport’s competitiveness and entertainment value.
Looking Forward
As GM ramps up development and Cadillac prepares for its debut, fans and analysts alike will be watching closely. With a fully American team and engine on the horizon, the 2029 season could be a defining moment for U.S. involvement in Formula One.
