FIA Approves General Motors F1 Power Unit For Cadillac Team In 2029

Cadillac’s Formula One effort has taken another step forward.

TWG GM Performance Power Units LLC., a company formed by TWG Motorsports and General Motors, has been approved by the FIA for use in 2029. The Cadillac F1 team will become the 11th team on the grid starting in 2026 and will use Ferrari power units for the three years leading to the now approved unit from GM.

Development and testing of the prototype engine will continue with plans for a dedicated facility for GM Performance Power Units closed to General Motor’s Charlotte Technical Center in 2026.

The approval is significant in that the Cadillac F1 effort will be wholly U.S. based by 2029. TWG Motorsports is the effort formerly headed by Michael Andretti under the Andretti Autosports umbrella. TWG Motorsports has said that they plan to have at least one American driver in the two car team.

Russ O’Blenes who was named CEO of the new venture said that with approval from FIA, they would continue to accelerate efforts to bring an American-built F1 power unit to the grid.

“Over two years ago, the FIA approved the entry of an eleventh team into the FIA Formula One World Championship, guided by my vision to expand the grid and bring new talent and opportunity to our sport,” said FIA President Mohammed Ben Sulayem adding that although the process was at times challenging – eluding to Andretti stepping aside as the head the effort and into the role of ambassador and advisor, to allow TWG Motorsports to eventually gain approval on the grid, “the progress we see today affirms the journey has been worthwhile.”

Ben Sulayem said that “welcoming GM Performance Power Units LLC. as an approved power unit supplier for the Championship starting in 2029 marks another step in the global expansion of Formula 1 and highlights the growing interest from world-class automotive manufacturers like General Motors.”

“Their dedication to innovation, sustainability, and competition is fully aligned with the FIA’s vision for the future of our sport. It also strengthens our commitment to making motorsport more accessible and inclusive worldwide—welcoming new manufacturers, advancing technology, and connecting with a broader, more diverse fan base.”
