Andretti's immediate hopes of joining the Formula 1 grid have been dashed after its bid to join was rejected after much discussion, leaving a 'window' until 2028.
In its statement, F1 found that adding an eleventh team to the World Championship “would not in itself add value to the institution” and that Andretti would not be a “competitive entrant”. Concerns were also raised over the possibility of a car being built to a set of regulations for 2025, only to be reformed in 2026. In a further rejection of Andretti's proposals, F1 suggested that the need to source a power unit for in the early seasons it would be “detrimental to the prestige of the league” and that the addition of an eleventh team would place an “operational burden” on match organisers. However, in an indication of a possible deal in the future F1 concluded that “we would otherwise consider an application to enter a team in the 2028 World Championship with a GM power unit”, an application which would add prestige to the Sport .
In October 2023 the FIA announced that Andretti was the only one of the candidate teams to pass the application process, thus advancing the bid to the next stage, which was commercial discussions with F1 itself. Andretti's efforts to join the F1 grid have been met with lukewarm reception by some F1 teams, who were unhappy at the prospect of sharing revenue at a rate of 11 instead of 10, despite Andretti claiming it could help increase of the total turnover. Andretti's bid is backed by General Motors and the Cadillac brand, which has agreed to build a power unit for the all-new 2026 rules, but not before 2028.
The project, spearheaded by former racer Michael Andretti, has been in the works for several years, having passed the FIA's initial vetting process last year. Mario Andretti, the 1978 F1 world champion and Michael's father, took to social media to express his disappointment at the decision.
