Sergio Perez says he is “enjoying the challenge” of Formula 1’s 2026 regulations despite his new team Cadillac encountering “a lot of issues” during the Barcelona shakedown. After a year out, Perez returns to F1 while Cadillac prepare for their first-ever season in the sport.

In 2026, America’s defining automotive rivalry finally enters F1, as Ford return to the sport through an engine partnership with Red Bul while General Motors (GM) debuts its very own team in Cadillac. It is expected they will compete at opposite ends of the F1 grid in 2026, but a war of words between the teams has already begun.
