General Motors, through its subsidiary Cadillac, is set to debut on the Formula 1 grid in 2026. The American automotive giant has been granted permission to join the premier class, provided it starts developing its own engines from 2028. For the first two years, the Americans will rely on an existing engine supplier. Ferrari announced on Tuesday that it has reached an agreement with Cadillac.
“Ferrari announces a multi-year agreement,” the Italians wrote in an official press release. “Starting in 2026, the company will supply engines and gearboxes to Andretti Formula Racing, led by TWG Global and General Motors.” As Cadillac is required to develop its own powertrain for Formula 1 from 2028, the collaboration with Ferrari is likely to last two years.
Currently, Ferrari supplies engines to the Haas and Sauber teams. However, from 2026, the Swiss racing team will become a factory team for Audi. Therefore, Scuderia would be particularly interested in finding a new customer. Suppliers indeed benefit from such collaborations. “The more power units in circulation, the more data we can collect,” explained Mercedes team boss Toto Wolff ahead of the Hungarian GP. “Ultimately, you can learn a lot from that.” Mercedes supplies engines to Williams, McLaren, and Aston Martin. From 2026, it will replace Aston Martin with Alpine.
