General Motors is set to become the first U.S. automaker with a Formula 1 team when a Cadillac-branded team joins the racing series in 2026, F1 announced Monday, ending a years-long battle between the series and former driver Michael Andretti, who initially proposed a GM expansion.

Formula 1 will expand the grid in 2026 to make room for an American team that is partnered with General Motors

Formula One announced Monday that “an agreement in principle” has been reached “with General Motors to support bringing GM/Cadillac” to the grid as the sport’s 11th team in 2026.

The Cadillac brand of General Motors Co. in Detroit will make its long-awaited debut in the Formula 1 World Championship in 2026, the automaker announced Monday. Cadillac Formula 1 will be the first new team to join F1 since 2016 and the 11th team on the grid.

Formula 1 could expand to 12 teams now that Cadillac has been accepted as the 11th from 2026, says FIA president Mohammed Ben Sulayem.

Formula One could expand to 12 teams now that General Motors' brand Cadillac has been accepted as the 11th from 2026, according to FIA president Mohammed Ben Sulayem. Formula One has always had provision for 12 in the rules but there was strong opposition from commercial rights holder Liberty Media and existing teams to going beyond 10 before a deal was reached.

General Motors and Cadillac face a “monumental task” to get ready to compete in Formula One for 2026, even if they could in theory get a head start on some design work, leading series figures said. The announcement last week General Motors’ Cadillac brand will be joining the grid as the 11th team from 2026 has been broadly greeted by drivers.
