Toyota is keeping the door open for a potential return to Formula 1 as an engine manufacturer, building on its new technical partnership with Haas.

Currently, Toyota Gazoo Racing, the motorsport arm of the Japanese carmaker, is collaborating with Ferrari-powered Haas, with the new team involving parts manufacturing, technical support, and simulation resources. However, Toyota Gazoo director Masaya Kaji has hinted at interest in developing F1 power units in the future.

"Morizo has told us, 'It's been 15 years since we were in Formula 1, so you need to learn,'" Kaji said, referring to Toyota chairman Akio Toyoda, in an interview with as-web.jp. "I think we need to understand a little more about various things and then consider this as the next step."

Speculation is growing about Toyota's potential return to Formula 1 as a full-fledged participant. Publications like Auto Motor und Sport suggest that Formula 1 may expand to include a twelfth team in the coming years, and Toyota's involvement could be a natural fit.

The upcoming 2026 technical regulations, which emphasize increased reliance on electrical power components, could provide Toyota with an opportunity to re-enter the sport.

When asked about his interest in the 2026 engine rules, Kaji responded: "Of course, I'm looking at everything there is to see. I think it will become a system that is easier to use in a variety of ways than it is now."

Despite its interest, Toyota is currently excluded from detailed discussions with F1, the FIA, and existing engine manufacturers about the 2026 power units.

"I think it would be good to participate in the meetings in order to learn," Kaji acknowledged. "But to participate, you need to be registered as a manufacturer with F1."
