Questions surround the latest version of the bid but the project known as Andretti Cadillac could receive Formula 1 approval within weeks.

One scenario has GM with Cadillac spending 2026 and 2027 as a F1 customer team before bringing its own powerplants in 2028.

Andretti could not get approval from F1 to enter. But the situation changed in September when he reduced his role with his namesake organization.

Momentum has reportedly shifted in the GM / Andretti team's favor, nearly a year after the initial rejection of the team's plan to join as an 11th F1 team.

A decision on the status of Andretti and their participation in Formula 1 could be made in the coming weeks, with a substantial increase in the chances of acceptance coming as a result of a restructuring within Andretti Global that meant Michael Andretti was put into a smaller role within the organisation.
