The world of Formula 1 has unveiled the simplified vocabulary that will be used to explain the advanced features of its new 2026 rulebook.

The championship is embarking on what is arguably the largest rules overhaul in its competitive history next season, featuring new chassis and engine rules and the mandatory use of 100% sustainable fuels.

The revised engines, which keep the hybrid V6 layout, boast a significantly increased energy storage, requiring major innovations in the aero packages.

During grand prix events, competitors will carefully oversee electrical energy – sometimes even hot laps – to achieve the optimal lap time.

Extensive fan consultation were carried out with a diverse audience, including dedicated enthusiasts and casual observers, to determine which terms would make things clearer of the central aspects of the upcoming rules.

The primary aim was to make a series of complex new areas of the competition as straightforward as possible for the broadest viewership.

Consequently, initial designations for specific components – such as "modes labelled X and Z" for the adjustable aero – have been phased out in preference for descriptive names that succinctly convey the primary purpose of the innovation.

What's the New Technology?

According to rule-makers that drivers will have increased agency to determine tactics regarding battery management, harvesting, and efficiency.

The new regulations feature a set of functions that will be clearly indicated on TV overlays to enhance the audience's understanding of the race battle.

• Attack Mode: This supersedes the existing Drag Reduction System. It provides a surge of additional ERS power available when a driver is close behind the car ahead to execute an overtaking maneuver.
• Boost Mode: This is a on-demand power boost from the hybrid system that can be used in attack or defence. It provides the pilot peak output at the push of a button.

Both of these key functions will have to be used with calculation, as the overall battery capacity is strictly limited.

• Active Aerodynamics: Both the nose and rear wings adjust their angles – opening on the long straight sections for low aerodynamic resistance and higher speed, and closing in the bends for peak grip.
• Energy Harvesting: Cars can recharge the energy store with regenerative braking, or during partial power application at the conclusion of a straight or in corners where only reduced throttle is applied.

2026 Car Specifications

The vehicles for the new era will be more compact and lighter relative to current models, with a wheelbase cut by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is projected to decrease by approximately 15-30%, although constructors will naturally regain performance as they develop their cars.

Air resistance has been reduced by 40%. The cars will utilize active aerodynamics – both wings will open on the straight sections to reduce drag and boost top speed and click back into place for optimal grip in corners.

Wheels will keep the current rim size, but the tyres themselves will be reduced in width, by 25mm at the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The 2026 engines will have an near-equal balance in energy output by the petrol engine and the electrical system, a rise from about one-fifth electric power in the current formula.

The hybrid system is made less complex through the elimination of the Motor Generator Unit – Heat, the complicated and costly unit that generated electricity from the turbocharger.

Every car on the grid will be required to run on 100% sustainable fuel, produced using plant-based materials or synthetic production methods.
