It seems that the Andretti F1 team's merger with the speed circus has been thwarted not by the project, but by one person in particular.
During the Las Vegas Grand Prix, several renowned international magazines reported that an agreement was close to announcing the new team. However, not in the way we had previously hoped. It seems that Michael Andretti's strong push was not well received by many, but his backing down could pave the way for a new American team. Another factor could have been the fact that one of Andretti's main sponsors, Mohammed bin Sulayem, is known for having poor relations with... everyone.
However, it now appears that General Motors has taken control, relying on Andretti's existing infrastructure. More importantly, they have an accepted status among other Formula 1 competitors. Their European center at Silverstone is already in place, their team of experts is developing well, and according to plans, Cadillac and Andretti would also appear, albeit with less emphasis.
Meanwhile, GM has already begun its own engine program for F1, and according to reports, the first operational engine could be launched in 2028. Thus, they would participate as a partner team for the 2026 debut, with Ferrari or Honda likely being considered. This all sounds very exciting, and considering recent times, we're closer than ever to making that wish come true with another Formula 1 team.
