As far as motorsport challenges go, it doesn't get much bigger than setting up a new Formula 1 team from scratch. Building one across continents to debut under the extremely complex 2026 regulations? If not mission impossible, then at least mission improbable.

The fact that Cadillac has pulled it off, meeting every deadline along the way and achieving respectability from the start, is a huge credit to the hundreds of men and women who were recruited in a short amount of time - many hired without even knowing if the team would be allowed onto the F1 grid at all.

But the squad is also adamant that without much-needed assistance from parent company General Motors, it wouldn't have made it at all.

It's well documented that Cadillac's road to F1 was a rocky one, starting life as a Michael Andretti-led effort before morphing into a de facto works effort from GM, which holds a minority stake in the team largely owned by TWG Global.

It's not just GM's marketing prowess or the prospect of a works power unit, which is currently under development while it takes Ferrari customer engines, that has made a difference to Cadillac's F1 fortunes, though.

By operating alongside a wide portfolio of the automotive giant's many racing programmes, including NASCAR, IndyCar, and sportscars, Cadillac has also been able to tap into GM's crucial resources to fast-track the development of its first-ever F1 car and the people that operate it.

"Obviously, GM's an equity shareholder in the team, so we have vested interest in it," Eric Warren, General Motors' Vice President of Global Motorsports Competition, told Motorsport. "Not only is the chassis named Cadillac, and it's called Cadillac Formula 1 team, but we see it as our team. From the very beginning when we decided to get involved, we wanted to really be an integral part of it as much as we could."

For the first year or two, GM had to prove to the FIA and to F1 management that this wasn't just a small start-up team or an IndyCar team coming over. This was truly GM being partners with TWG. So a lot of the early technical work was really building up the foundation that the team needed to be able to operate at the pace of Formula 1.

In Cadillac F1's case, before it entered a race against 10 established rivals, it had to embark on a race against time to even get there, with the finish line the start of the Sakhir Grand Prix in Australia at the start of March.

That truncated timeline between setting up the foundation of the team, being officially accepted, and making its 2026 debut meant that it could not have possibly had all the right hardware and infrastructure in place at its current base in Silverstone. This is where the GM Charlotte Technical Centre comes in. Opened in 2022 and located on the campus of NASCAR stalwart Hendrick Motorsports in Concorde, North Carolina, the Centre played a pivotal role.
