General Motors are currently making budget provisions for the construction of an F1 engine and could even divert resources from their World Endurance Championship programme with Cadillac to the F1 project, according to Auto Motor und Sport

The German publication also reports that the American car giant has already “recruited F1-known personnel for the management positions”. 

Andretti Formula Racing’s bid to enter F1 with General Motors’ Cadillac brand was given the green light by motorsport’s governing body, the FIA, on Monday. 

According to AMuS, an EU directive effectively made it impossible for the FIA to reject Andretti.

But Andretti must now await approval from F1’s American owners Liberty Media before they can officially become the 11th team on the grid. 

The assessment period is likely to last months and F1 is widely expected to reject Andretti’s bid, the BBC report. 

Andretti’s quest to join the F1 grid has so far been met with a mixed response from the sport’s bosses and existing teams. 

F1’s current Concorde Agreement permits as many as 12 teams to take part in the world championship up to and including the 2025 season.
