Cadillac’s F1 chief announces that General Motors will develop its own power unit and bring it online in Formula 1 for Cadillac in 2029, initially using Ferrari power units as a customer before switching to a GM-built PU.

The project will enforce a strict IP separation, with Ferrari supplying engines to the current customer team while GM develops its own power unit internally, ensuring no cross-communication of technical IP between the two streams.

GM aims to evolve Cadillac into a works team by building its own PU, keeping IP separate from Ferrari’s, and producing GM-developed engines for on-grid competition.

Towriss notes regulatory uncertainties but projects no delay to the 2029 target, while acknowledging that changes could occur before 2031.

If PU regulations shift in 2030 or 2031, Cadillac may need a redesign sooner than 2031, but the priority remains a Cadillac PU on the grid as soon as possible.

The GM PU program is reportedly ahead of schedule, with ongoing monitoring of evolving F1 engine rules that could impact the PU’s lifespan if regulations change in 2031.

Current engine regulations run through 2030, and anticipated changes in 2031 could limit a GM PU’s window, yet the goal remains a 2029 debut.

Towriss confirms Ferrari’s supply agreement continues through 2028, with Ferrari’s involvement described as positive and supportive.

GM Performance Power Units LLC, formed in 2025 in Concord, NC, is tasked with Cadillac’s in-house PU development while Cadillac remains a Ferrari customer for 2026–2028.

The initiative marks a significant shift for Cadillac and GM from customer use to an autonomous, long-term power unit program, aiming to compete with Mercedes, Ferrari, Audi, and Red Bull.
