GM’s Cadillac brand is part of an ongoing bid by the Andretti team to enter the sport which has yet to be formally approved. Last month, Andretti’s entry was approved by F1’s governing body the FIA. Initially, Andretti and GM’s plan was to badge a Renault engine with the Cadillac brand for its entry in 2025. Privately, F1 has been opposed to the idea of admitting a new team, but in recent weeks the feeling within the sport is that they might ultimately have to accept Andretti. Reuss said the decision to build its own engine would “position Andretti Cadillac as a true works team”.
