What direction should Cadillac take as a future engine manufacturer amid uncertainty around the PU rules?

Cadillac’s preparations for its full works entry into Formula One continue to gather momentum, but the manufacturer remains deeply involved in the sport’s ongoing discussions about the 2027 power‑unit framework.

Although General Motors will not introduce its own engine until 2029, its status as a registered power‑unit manufacturer gives it a vote in the negotiations — and CEO Dan Towriss made clear during the Monaco Grand Prix weekend that the process remains complex and far from complete.

Asked for Cadillac’s position on the proposed 2027 changes, Towriss emphasised that the discussions are still evolving. “I think with respect to the ’27 engine, again, there’s just, it’s a work in process. There’s a lot of work to do,” he said.

The challenge, he explained, lies in the fact that any adjustment to the regulations inevitably affects some manufacturers more than others. “I think it’s a complex negotiation, as you can imagine. One change may benefit one team or one group more than the other, and there’s a lot of work to do.”

Towriss also warned against rushing decisions that could have far‑reaching technical consequences. “I think the main thing is that we can’t go, while time is of the essence, we can’t go too fast. It’s very complex.

"There’s a lot of modelling work that needs to be done to understand what these changes can achieve on track for the drivers without reopening homologation or doing too much to the chassis as well. And so that remains to be seen.”

While the 2027 debate continues, Cadillac’s long‑term engine programme remains firmly on schedule. “As to the future power unit, we’re on track for a V6 power unit in 2029,” Towriss confirmed.

But he also acknowledged that the sport is already looking beyond that generation of engines — and that GM is prepared to follow. “There’s also talk of a V8 coming later as well, and I think as GM has gone on the record, we’d be very happy to build a V8 engine as well.”

For now, the manufacturer remains fully engaged in the regulatory process, even without a 2027 engine of its own. “A lot of work, a lot of negotiation across the power unit manufacturers left to do, and we’ll see what happens,” Towriss concluded.
