Andretti, and subsequently Cadillac, won't be joining the Formula 1 grid anytime soon.
The governing body of the Formula 1 World Championship approved Andretti Global's Formula 1 bid in October on a technical basis. The team would enter the sport and mark the 11th team on the grid. Rules allow for up to 13 teams.
“Our assessment process has established that the presence of an 11th team would not, in and of itself, provide value to the Championship,” F1 said in a statement.
Andretti Cadillac told Motor Authority, “Andretti Cadillac has reviewed the information Formula One Management Limited has shared and strongly disagree with its contents. Andretti and Cadillac are two successful global motorsports organizations committed to placing a genuine American works team in F1, competing alongside the world’s best. We are proud of the significant progress we have already made on developing a highly competitive car and power unit with an experienced team behind it, and our work continues at pace.Andretti Cadillac would also like to acknowledge and thank the fans who have expressed their support.”
With the rejection of Andretti Global's bid came word that the outfit has a good chance of joining the grid in 2028 if General Motors follows through on its plans to build its own F1 unit.
The original plan called for Andretti to use a Renault power unit initially with Cadillac branding.
F1 noted in its statement concern with a new, novice, team being competitive with a new car and power unit in 2025 before having to then prepare a new power unit for the updated 2026 regulations.
F1 will introduce a new power unit in 2026. The new powertrain will be similar to today's, which combines a turbocharged 1.6-liter V-6 with hybrid systems. The goal will be to lower emissions by reducing power from the engine and increasing output from the hybrid systems.
