The United States will have a second team competing in Formula 1 from 2026, when Cadillac Formula 1 will join the sport as its 11th team. The result is a complete 180 for the sport’s owner, which was highly resistant to the initial bid, first announced at the beginning of 2023.

“As the pinnacle of motorsports, F1 demands boundary-pushing innovation and excellence. It’s an honor for General Motors and Cadillac to join the world’s premier racing series, and we’re committed to competing with passion and integrity to elevate the sport for race fans around the world,” said GM President Mark Reuss. “This is a global stage for us to demonstrate GM’s engineering expertise and technology leadership at an entirely new level.”

Team first, engines later

We will have to wait until 2028 to see that full engineering potential on display. Even with the incoming changes to the technical regulations, it’s far more than the work of a minute to develop a new F1 hybrid powertrain, let alone a competitive package. Audi has been working on its F1 powertrain since at least 2023, as has Red Bull, which decided to make its internal combustion engine in-house, like Ferrari or Mercedes, with partner Ford providing the electrification.

GM’s decision to throw Cadillac’s hat into the ring came with the caveat that its powertrain wouldn’t be ready until 2028—two years after it actually wants to enter the sport. That means for 2026 and 2027, Cadillac F1 will use customer engines from another manufacturer, in this case Ferrari. From 2028, we can expect a GM-designed V6 hybrid under Cadillac F1’s engine covers.

As McLaren has demonstrated this year, customer powertrains are no impediment to success, and Alpine (née Renault) is going so far as to give up its own in-house powertrain program in favor of customer engines (and most likely, a for sale sign as the French automaker looks set to walk away from the sport once again).
