Cadillac will source their Formula 1 power units from Ferrari until they are ready to build their own by 2028, but now reports claim they will also get their suspension elements from the Italian team.
The agreement between Ferrari and Cadillac dates back to December 2024 and was inked after Formula One Management (FOM)
gave the final green light for Cadillac after Michael Andretti was removed from the picture.
The plan for Cadillac is to join the F1 grid in 2026 when the new chassis and power unit regulations will kick in and will use Ferrari power units and gearboxes up to 2028, when the American automaker will start producing their own F1 power unit.
If Cadillac goes ahead with Ferrari suspension, they will not be the first team to follow such a model, as Haas uses Ferrari suspension, while Racing Bulls use Red Bull suspension. Aston Martin, on the other hand, procures the whole rear end of their car from Mercedes along with the power unit.
Having Ferrari suspension will allow Cadillac to focus on other aspects of their F1 project, as time is of the essence with 2026 not far away, with the US squad facing a monumental task to put two cars on the grid despite earlier preparations done since the Andretti days with a base created in the UK.
Graeme Lowdon has been appointed to lead the Cadillac F1 project, with Pat Symonds also on board as a technical consultant for the team.
In terms of drivers, Cadillac would probably be looking to have a US driver within their lineup; Colton Herta maybe? While rumors are circulating that Sergio Perez, who was let go by Red Bull at the end of the 2024 season, may be considered for the other seat and is in talks with the newly created American squad.
