Cadillac provide update on when in-house F1 engine might make debut

Cadillac have shared an update on when they expect to debut their own power unit in F1, with the new team still focused on their original target of 2029 whilst acknowledging that they will “speed up” the process if there are ways to do so.

After Cadillac’s entry for 2026 received its final approval in March 2025, it was confirmed one month later that GM Performance Power Units LLC. – founded by TWG Motorsports and General Motors to build powertrains for the Formula 1 team – had been officially approved as an F1 power unit supplier starting in 2029 by the FIA.

Speaking to a select group of media, including F1.com, TWG Motorsports boss Dan Towriss was quizzed ahead of the team's 2026 debut on whether this timescale for the engines was still the plan, with his response being that the hope is for Cadillac’s own power unit to be up and running “as soon as possible”.

“We’re really following the conversation on the [regulations] closely,” Towriss explained. “It’s possible that the regulations could change before 2031, it’s possible that they don’t change before 2031.

“Regardless of the funding, I think it’s important that we see a Cadillac power unit on the grid as soon as possible, and so that’s really the main focus from my standpoint. If there are ways to speed it up, we will, but right now the focus is still 2029.”

Towriss also shared news on how work is progressing on the team’s new United States headquarters in Fishers, Indiana, which will run alongside their European facility next to the Silverstone track.

“We’re hoping that construction to wrap up later this year or in the first quarter of 2027, as we continue to get the building right and figure out exactly the manufacturing components that are going to be there, so we’re super excited,” said Towriss.

“That’s going to be a state-of-the-art facility. Right now a lot of the teams that are in that location are working out of temporary office space as we complete the design there.”

And while Cadillac’s own power unit will not make an appearance just yet, the team’s engines and gearboxes are being supplied by Ferrari in the meantime.

Pushed on how the American outfit have found the experience of working with the Scuderia, Towriss responded: “Ferrari’s been great to work with.

“Fred [Vasseur] and his team have been really good and supportive from that standpoint, even through Barcelona [Shakedown], so we’re very happy with the Ferrari relationship and how that’s going.”
