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.

Starting in 2026, a new set of sporting regulations won't be the only major change coming to Formula 1. As reported by ESPN, Formula 1 has reached an agreement with General Motors to add an 11th team to the grid.

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.

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

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.

After a very public failed attempt by Michael Andretti to bring another American team to Formula 1, General Motors has fought through the bureaucracy and politics to join the grid as a works team in 2026. The announcement came this morning after the series just wrapped up the Las Vegas Grand Prix over the weekend.

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.
