The world of Formula 1 has introduced the simplified vocabulary that will be used to describe the intricate details of its revolutionary 2026 technical rules.

The racing series is implementing what is considered the most significant rules overhaul in its long history next season, featuring fresh chassis and power unit regulations 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, requiring significant developments in the vehicles' aerodynamic design.

During grand prix events, pilots will carefully oversee battery power – potentially on hot laps – to achieve the optimal performance.

Wide-ranging research were carried out with a mix of viewers, including new, casual and core fans, to identify which phrases would aid comprehension of the key features of the upcoming rules.

The stated goal was to render a range of advanced new areas of the sport as straightforward as possible for the broadest viewership.

Consequently, older technical labels for specific components – such as "x-mode and z-mode" for the adjustable aero – have been discarded in preference for descriptive names that directly explain the real-world effect of the innovation.

Key Technical Innovations

Regulators explain that drivers will have more power to determine tactics regarding battery management, harvesting, and conservation.

The upcoming changes introduce a range of settings that will be shown on broadcast screens to enhance the viewers' comprehension of the race battle.

• Passing Mode: This supersedes the current DRS. It provides a short boost of battery power accessible when a driver is within one second the vehicle in front to execute an pass.
• Extra Push Mode: This is a manual energy deployment from the ERS that can be deployed for attack or defence. It grants the pilot peak output at the activation of a control.

Both of these crucial modes will have to be deployed strategically, as the overall battery capacity is capped.

• Active Aero: Both the front and rear wings move automatically – spreading on the straights for reduced drag and increased velocity, and angling down in the turns for optimal cornering performance.
• Energy Harvesting: Cars can replenish their battery with power recovered from braking, or during partial power application at the end of straights or in certain corners where only reduced throttle is used.

Car Design Evolution

The next-generation machines will be reduced in size and weight relative to current models, with a car length cut by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the minimum weight decreased by 30kg.

Overall downforce is anticipated to be reduced by approximately fifteen to thirty percent, although teams will undoubtedly recover some as they develop their cars.

Aerodynamic drag has been reduced by 40%. The vehicles will utilize moveable wing elements – front and rear wings will open on the straight sections to reduce drag and increase straightline speed and revert into place for peak handling.

Pirelli tyres will keep 18-inch wheel rims, but the tyres themselves will be reduced in width, by 25mm at the front and 30mm at the rear.

What's Changing in the Engines?

The revised hybrid units will have an near-equal balance in horsepower generated by the petrol engine and the electrical system, a rise from about 20% battery contribution this year.

The ERS setup is streamlined through the removal of the complex turbo energy recovery device, the intricate and expensive component that harvested power from the turbocharger.

Cars will be obliged to compete on fully sustainable fuel, created from organic sources or synthetic industrial processes.
