General Motors has announced it has formally registered with the FIA as a Formula 1 power unit manufacturer from the 2028 season.
The American brand has partnered with the Andretti Global entry bid, with commercial discussions the final hurdle before Andretti Cadillac Racing can join the grid as an 11th team.
There has been stiff opposition to the entry from F1's incumbent teams over the value the bid can bring to the sport, which means this announcement marks a large stride in Andretti and GM's push to overcome the pushbacks.
It means GM will join Red Bull-Ford, Ferrari, Honda, Mercedes, Alpine-Renault and Audi as power unit suppliers.
