How big are the new F1 cars? 2026 regulations explained

2026 F1 cars get a major redesign. They'll be smaller, lighter, and feature active aero that adjusts automatically based on speed - like "Z-mode" for straights and "X-mode" for corners. This aims to make racing closer while keeping F1 cars as the pinnacle of technology.

Smaller, lighter cars
Active aerodynamic elements introduced
Multiple aero modes for different conditions
Designed for closer racing

Official FIA Text

For 2026, cars will feature revised aerodynamic regulations including active aerodynamic elements. The front and rear wing configurations will change to reduce downforce in certain conditions while maintaining close racing ability. Smaller overall dimensions aim to reduce car weight and improve racing.

2026 Power Unit Regulations

Chapter: Chapter II - Power Unit Changes

In Simple Terms

2026 brings major engine rule changes. The complex MGU-H is removed to cut costs and attract new manufacturers. To compensate, the MGU-K becomes much more powerful and the battery is bigger. The goal is simpler, more sustainable power units that are still cutting-edge.

MGU-H removed from power units
MGU-K power increased significantly
Larger energy store capacity
Aims to attract new manufacturers

Official FIA Text

For 2026, the power unit will comprise a 1.6 litre V6 turbocharged internal combustion engine with a significantly enhanced electrical component. The MGU-H will be removed. The electrical power output will increase substantially with a more powerful MGU-K and larger energy store.

Additional Power Unit Units

Chapter: B8

In Simple Terms

In 2026, drivers get one extra Power Unit component for free if their engine manufacturer is brand new to F1 that season. This is a one-time allowance to help new manufacturers get up to speed without penalty concerns.

New Power Unit manufacturers in 2026 get one additional allocation of each engine component
This concession only applies to manufacturers in their first year of supplying F1 engines
The extra unit applies to all Power Unit elements defined in Article B8.2.2
This is a regulatory allowance, not a penalty relief measure

Official FIA Text

Each driver will be permitted to use an additional unit for each of the Power Unit elements in Article B8.2.2 in the 2026 Championship if the Power Unit is supplied by a PU Manufacturer in its first year of supplying Power Units.
