The 2026 Rules:
Why Everything Changed
The 2026 season introduces the biggest set of rule changes in the history of the sport. Here is the summary of what is new.
What Changed in F1 for 2026?
The 2026 regulations represent a "clean sheet" design. The FIA (F1's governing body) wanted to make the cars smaller, lighter, and more environmentally friendly, while keeping the racing exciting.
TL;DR: The Key Changes
- ●Smaller Cars: 20cm shorter and 10cm narrower.
- ●New Engines: 50% electric power, 100% sustainable fuel.
- ●Active Aero: Wings that move on straights to reduce drag.
- ●Manual Override: A "Push-to-Pass" button replacing DRS.
1. The "Nimble" Car
Cars had become too big and heavy. The new rules force them to shrink.
- 📏Width: Reduced by 10cm (1900mm).
- ⚖️Weight: Reduced by 30kg (768kg).
- 📉Downforce: Reduced by 30% to improve racing.
2. The 50/50 Engine
The power unit has been completely redesigned to be relevant to road cars.
More Electric
The electric motor (MGU-K) now provides nearly 50% of the total power (350kW).
Sustainable Fuel
The internal combustion engine runs on 100% sustainable "drop-in" fuel.
3. Active Aerodynamics
DRS is dead. Instead, the whole car changes shape.
- Z-Mode: High downforce for corners.
- X-Mode: Low drag for straights (wings flatten out).
This is available to everyone, not just when overtaking.
4. Manual Override
To replace the overtaking aid of DRS, drivers now have a "Push to Pass" style system.
If you are close to the car ahead, you get a boost of electrical energy at high speed (up to 337km/h) while the leading car runs out of battery power.
