Ferrari has announced that it has entered into a multi-year agreement to supply power units and gearboxes to the GM-Cadillac Formula 1 team upon its expected debut in 2026.

This partnership marks a major milestone for both Ferrari and Andretti Formula Racing, the team spearheading Cadillac’s entry into Formula 1.

The announcement comes after Andretti Formula Racing, backed by TWG Global and General Motors, secured from Formula 1 a provisional approval to join the F1 grid in 2026.

Final confirmation from the FIA is still pending, but Ferrari’s support is a pivotal development for the project.

A Ferrari statement confirmed the deal:

"Ferrari N.V. today announces a multi-year agreement starting from 2026 with Andretti Formula Racing LLC, regarding the supply of power unit and gearbox to the racing team led by TWG Global and General Motors, subject to Andretti Formula Racing LLC receiving written confirmation from the FIA – F1 that its entry to the 2026 FIA Formula One Championship has been accepted and approved."

While GM still intends on developing its own in-house Cadillac-branded F1 power unit, this milestone is only feasible by 2028 at the earliest.

Ferrari’s supply will bridge the gap for the first two seasons, allowing the team to compete while refining its future plans.

This marks a return to two customer teams for Ferrari. Haas will remain a close customer, while Sauber, currently Ferrari-powered, is set to transition to Audi engines as the German marque takes over the Swiss team as a full works outfit in 2026.

The Cadillac F1 project has been redefined under the stewardship of TWG Global, which took control of Andretti Global earlier this year.

Unlike the previous Andretti F1 proposal, which faced rejection, the rebranded GM-backed bid has gained momentum, partly due to its association with General Motors and the manufacturer’s ambition to develop its own engine.

The deal positions Ferrari as a key player in fostering the expansion of the Formula 1 grid while securing additional revenue streams. GM, on the other hand, gains access to Ferrari’s proven engine technology, providing a competitive platform for its entry and boosting Cadillac’s brand presence in Formula 1.

GM and TWG Global recently appointed Graeme Lowdon as team principal, cementing the project’s leadership structure. Lowdon, a veteran of Virgin, Marussia, and Manor Racing, has been instrumental in guiding the team through its initial development stages over the past three years.

With Ferrari power at its heart, the Cadillac F1 project is poised to shake up the grid in 2026, bringing together iconic American and Italian automotive names in a partnership that could redefine both brands’ roles in Formula 1’s rapidly evolving landscape.
