Cadillac F1 Partners With Ferrari For Engine And Gearbox Supply

Ferrari has announced a multi-year agreement to supply power units and gearboxes to the Cadillac F1 team, starting in the 2026 season.

This strategic partnership ensures Cadillac, backed by General Motors, can hit the ground running when they join the F1 grid the season after next. The deal allows them to leverage Ferrari's experience while they develop their own power unit, expected to be operational by 2028. The powertrain and gearbox supply will shift over from Sauber as it transforms into Audi F1.

Sauber is an interesting case, however. In 2024 the team used Ferrari gearbox internals but developed its own casing in order to use a pull-rod rear suspension—Ferrari used a pushrod rear design in 2024. It's unclear at this point if Cadillac will choose to use Ferrari's casing, and subsequently its rear suspension design. Of course, none of this could matter once 2026 rolls around.

The collaboration is expected to be a major boost for F1's popularity in the US, bringing together two iconic brands with rich motorsport legacies. 2026 is shaping up to be a rather confusing year for nomenclature with Cadillac Ferrari, Aston Martin Honda, and Alpine Mercedes set to line up on the grid.

"We are delighted to be supplying the [Cadillac] team with our power unit and gearbox," said Ferrari team principal Fred Vasseur. "It means we will continue to have two 'customer teams' in the championship with all the benefits this brings in terms of technical development within Ferrari."

Meanwhile, Cadillac has appointed former Manor sporting director Graeme Lowdon as their team principal. "Choosing the right power unit partner is crucial, and we trust in Ferrari's passion, excellence and the exceptional capabilities of their people," Lowdon said.

GM is expected to develop its own powertrain for debut in 2028. According to reports the company has already started work on a dedicated powertrain development center in Charlotte, North Carolina.
