HONDA The Power of Dreams

Formula 1 cars are designed and manufactured using each team’s proprietary technology. The power unit (PU)—the car’s core system—is supplied by a designated PU manufacturer. All components must comply with the detailed regulations defined by the Fédération Internationale de l’Automobile (FIA), within which teams and manufacturers apply the latest and highest levels of technology. Tires are supplied under a single-make system by Pirelli. For each race, three different dry-weather tire compounds are allocated, excluding intermediate and wet tires.

Car numbers have been selected by drivers since 2014. The reigning Drivers’ Champion is permitted to use car number #1. Previously, car numbers were assigned to teams based on Constructors’ Championship standings, with each team using consecutive numbers. This system was changed to fixed driver numbers to improve clarity for fans and make drivers easier to identify from season to season.

In 2026, both the chassis and the power unit will undergo significant changes.

The new car concept aims to promote closer racing through revised vehicle design, while the power unit regulations emphasize enhanced environmental performance and sustainability. In addition, strict budget cap regulations are introduced to address rising development costs.

Key changes include:

Chassis:

• - Ground-effect aerodynamics that generate downforce from the underfloor will be eliminated, reducing overall downforce.
• - The DRS (Drag Reduction System) will also be removed, and active aerodynamics will be introduced, allowing the front and rear wings to adjust on straights and in corners to improve overtaking.
• - Overall vehicle size and weight will be reduced to enhance agility and dynamic performance.

Power Unit (PU):

• - The MGU-H will be eliminated, while energy recovery capability of the MGU-K will be significantly increased.
• - The output ratio between the internal combustion engine (ICE) and the electric motor will shift to 50:50, substantially increasing the contribution of electric power.
• - Fuel will be 100% sustainable fuel.

Further details are specified in the 2026 Formula 1 Regulations.

While chassis development remains the responsibility of each team, power units are supplied by five manufacturers: Honda, Mercedes, Ferrari, Ford (via Red Bull Powertrains), and Audi. Cadillac F1 Team will use Ferrari-supplied power units for its first two seasons, with a newly developed power unit by General Motors scheduled for introduction from 2028.
