2026 Season — Regulations

The 2026 regulations represent F1's most ambitious transformation yet, redefining the sport's relationship with sustainability, technology, and spectacle. The new power unit formula removes the MGU-H (the complex and expensive turbo-hybrid component) while doubling the electrical power output, creating an approximately 50/50 split between internal combustion and electric power (around 400 kW ICE + 350 kW electric). This makes the 2026 cars the most powerful hybrid racing machines ever built. The switch to 100% sustainable fuel — fully synthetic, carbon-neutral — is a landmark moment for motorsport. The fuel is produced from non-food biological sources and carbon capture, demonstrating that high-performance racing can be achieved without fossil fuels. Active aerodynamics replace DRS, which was abolished after the 2025 season. The new system features driver-selectable "corner mode" and "straight-line mode" on both front and rear wings, providing a more sophisticated and fair overtaking mechanism. The cars are significantly smaller and lighter (768 kg, down 30 kg from 2025's 800 kg) with reduced ground effect (flatter floors, increased ride height). The budget cap was restructured to $215M for the chassis (items previously outside the cap folded in) with a separate $130M power unit cap. The grid expanded to 22 cars with Cadillac's entry as the 11th team. The engine allocation was set at 4 ICE, 4 TC, 4 EX + 3 MGU-K, 3 ES, 3 CE per season, with a first-year exception for new manufacturers. Sprint races continue at 6 events, with venues including China, Miami, Canada, Britain, Netherlands, and Singapore. The calendar features 22 rounds, down from 2024-2025's peak of 24.
