Formula 1 has revealed the simplified vocabulary that will be used to describe the intricate details of its revolutionary 2026 rulebook.

The sport is introducing what is considered the most significant regulation change in its illustrious history next season, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which keep the 1.6-litre V6 turbo hybrid, boast a substantially higher battery power, driving significant developments in the vehicles' aerodynamic design.

During grand prix events, pilots will strategically manage electrical energy – potentially on flying laps – to extract the best lap time.

Wide-ranging research were undertaken with a diverse audience, including dedicated enthusiasts and casual observers, to determine which terms would make things clearer of the main elements of the 2026 changes.

The primary aim was to make a set of intricate technical aspects of the competition as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for specific components – such as "modes labelled X and Z" for the adjustable aero – have been discarded in favour of intuitive labels that directly explain the real-world effect of the technology.

What's the New Technology?

Regulators explain that racers will have increased agency to choose strategies regarding power usage, harvesting, and conservation.

The 2026 rules introduce a set of functions that will be clearly indicated on TV overlays to improve the fans' insight of the race battle.

• Passing Mode: This takes over from the existing Drag Reduction System. It provides a surge of additional ERS power deployable when a driver is within one second the car ahead to facilitate an pass.
• Extra Push Mode: This is a manual power boost from the ERS that can be deployed for attack or defence. It provides the driver peak output at the push of a button.

Both of these crucial modes will have to be managed carefully, as the total energy is capped.

• Active Aerodynamics: Both the car's wings move automatically – opening on the long straight sections for reduced drag and top speed, and angling down in the corners for maximum downforce.
• Energy Harvesting: The system can replenish their battery with energy harvested under braking, or during partial power application at the conclusion of a straight or in corners where only limited engine output is used.

Car Design Evolution

The next-generation machines will be more compact and lighter compared to the 2025 spec, with a car length reduced by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Overall downforce is projected to decrease by approximately fifteen to thirty percent, although teams will undoubtedly recover some as they optimize their packages.

Drag has been cut by 40%. The cars will feature active aerodynamics – both wings will open on the straight sections to improve speed and boost top speed and click back into place for peak handling.

Tyres will keep 18-inch rims, but the tyres themselves will be slimmer, by 25mm at the front and 30mm at the rear.

Power Unit Revolution

The new power units will have an approximate 50-50 split in energy output by the internal combustion engine and the ERS, increasing from about one-fifth electric power this year.

The ERS setup is streamlined through the removal of the MGU-H, the intricate and expensive device that recovered energy from the turbocharger.

Cars will be required to run on 100% sustainable fuel, manufactured from plant-based materials or synthetic production methods.
