Formula 1 CEO Stefano Domenicali has highlighted the 2026 power unit regulations as crucial in drawing major manufacturers like Cadillac and Audi to the series. The new rules feature a 50:50 balance between sustainable fuel combustion and electric power, aligning with broader automotive trends. Domenicali emphasized the excitement around these changes and their role in bolstering F1's innovation.
Formula 1 is set for significant transformation with the 2026 regulations, particularly in power units that split output equally between internal combustion engines using sustainable fuels and electric power. This approach, according to CEO Stefano Domenicali, has been instrumental in attracting high-profile entrants to the grid.
Domenicali expressed enthusiasm about Cadillac's arrival as the 11th team, noting in an interview with F1.com: "Well, it’s very exciting. Cadillac is one of the most important manufacturers in the world. They're going to invest a lot. They're going to bring new energy, and I believe that’s related to the fact that we have taken the right technical decision with regard to the regulations."
He linked the regulations' focus on advanced sustainable fuels to widespread interest from the industry. Beyond Cadillac, the power unit rules have influenced other partnerships: Ford with Red Bull Powertrains, Audi's takeover of Sauber, and Honda's new alliance with Aston Martin following its split from Red Bull at the end of 2025.
"The powertrain has been relevant not only to attract Cadillac, but we have Audi, we have Honda. So it's a great moment for all of us," Domenicali added. He underscored F1's leadership in innovation, stating: "F1 has been always at the forefront of innovation, future connectivity, attraction, attention and therefore that's what we are doing. That's why I do believe today F1 has never been so strong."
The CEO described the introduction of new regulations as a thrilling period that draws technical attention, engages hundreds of engineers, and extends benefits beyond the sport. Drivers and teams alike are adapting to the changes, heightening anticipation for 2026.
