Formula 1 CEO Stefano Domenicali has called for stakeholders to agree on the next generation of power unit regulations as early as this year. He emphasized the need to act quickly due to long lead times, while respecting investments from manufacturers like Audi and Honda. Domenicali backs lighter, simpler engines centered on sustainable fuel and strong internal combustion.

Formula 1's power unit manufacturers are preparing to vote on a proposal for additional tests to measure engine compression ratios under operating conditions. The change, aimed at addressing concerns over a potential loophole in the 2026 regulations, would require compliance checks at 130 degrees Celsius starting from August 1, 2026. The vote, submitted via email, is expected to conclude within 10 days.

The Cadillac Formula 1 team has chosen to limit its use of Ferrari parts beyond power units and gearboxes, aiming for greater autonomy in its debut seasons. This approach differs from that of fellow Ferrari customer Haas, which relies more heavily on Maranello's components. Cadillac's strategy supports its long-term goal of developing its own engines by 2029.
