Domenicali: 2026 F1 rules key to attracting Cadillac, Ford

Formula 1 CEO Stefano Domenicali credits the sport's 2026 technical regulations for successfully attracting major automotive brands like Cadillac and Ford back to the championship. The new rules, featuring a 50/50 power split between sustainable-fueled internal combustion and electric energy, are designed to align F1 with the broader automotive industry's future, creating what Domenicali calls "a great moment for all of us."

Why it matters:

The influx of major manufacturers validates F1's strategic pivot towards sustainability and road-relevant technology. After years of engine formula uncertainty, the 2026 rules have provided a stable and attractive framework for investment, proving the championship's commercial and technical appeal to global brands beyond its traditional European base. This manufacturer confidence is crucial for the sport's long-term growth and technological credibility.

The details:

• The 2026 power unit formula mandates an even split between ICE power using advanced sustainable fuels and electrical energy, a balance directly relevant to the automotive sector's development path.
• New Entrants: The regulation shift has already borne fruit with Cadillac entering as a new constructor for 2026, Ford partnering with Red Bull Powertrains, and Audi completing its takeover of the Sauber team.
• Manufacturer Endorsement: Domenicali explicitly linked Cadillac's decision to the "right technical decision," stating the sustainable fuel focus was a central attraction. He also noted the rules were relevant in retaining Honda, which will power Aston Martin from 2026.
• Innovation Cycle: The F1 CEO highlighted that new regulations naturally accelerate technical competition and fan interest, as hundreds of engineers and drivers adapt to a fresh challenge, with benefits that extend beyond the racetrack.

What's next:

The focus now shifts to execution. The 2026 season will be the ultimate test of whether these new regulations deliver on their promise of exciting racing and technical innovation. The arrival of Cadillac and the full integration of Audi and Ford will reshape the competitive dynamic, potentially challenging the current hierarchy. All eyes will be on the pre-season tests in early 2026 to see which teams have best interpreted the new rulebook.
