Cadillac sets date for major F1 engine milestone

Cadillac is putting the building blocks of its Formula 1 future firmly in place, with General Motors preparing to open its dedicated power unit facility in Charlotte, North Carolina, on December 18.

The milestone marks a significant step in the American manufacturer’s ambition to become a fully fledged F1 constructor, developing its own engines after initially entering the championship as a customer of Ferrari.

GM received FIA approval to become a power unit supplier from 2029, giving the company a couple of years to complete its development programme before its homegrown machinery reaches the grid.

General Motors president Mark Reuss confirmed the timetable while speaking at the Autosport Business Exchange in New York, offering an encouraging update on the project.

“We're opening our whole engine factory, if you will, in Charlotte, North Carolina on 18 December,” Reuss announced. “So that's coming really well.”

A long road from the back of the grid

Cadillac’s immediate challenge is considerably less glamorous than its long-term ambitions.

The team has endured a difficult debut season in 2026, remaining the only outfit without a championship point, while its MAC-26 has qualified last at each of the past four rounds.

Reuss, however, insists the project is about building lasting competitiveness rather than accepting a place at the back of the field.

“You know, we’re not here to finish last, so we’ve got to follow through and build this team, build the powertrain and build the car, like we did in GTP,” he said.

“That takes a little more time here, because this is a place where we've never raced. You’ve got to get the right people with the right engineers and the right drivers, and we’ve got to get that process really going, and it's logarithmic, it's not linear.”

The challenge is compounded by uncertainty over F1’s future engine regulations. FIA president Mohammed Ben Sulayem has advocated a return to V8 power by 2031, potentially limiting the lifespan of GM’s first-generation F1 power unit to just a handful of seasons.

Perez and Bottas provide a valuable foundation

In the meantime, experienced drivers Sergio Perez and Valtteri Bottas are helping Cadillac navigate its growing pains. Despite suffering difficult results, both veterans bring an understanding of the patience and precision required to develop a new operation.

“You can't win every race – no one can win every race – so when it happens, when they have a day that is unfortunate, or mistakes were made, they move on from that race and perfect their craft – whether it's with the car or themselves, or their physicality, or whatever that is – and they drive for that perfection,” Reuss said.

“Both of these gentlemen in the race for us do that, and they really understand what it takes and the process. I'm very, very happy that they're patient with us, to be honest; that takes a special person.”

December’s factory opening will obviously not deliver instant results on track, but it will bring Cadillac another step closer to controlling its own destiny in Formula 1.
