The world of Formula 1 has introduced the simplified terminology that will be used to describe the technical complexities of its new 2026 rulebook.

The racing series is implementing what is considered the biggest technical shift in its illustrious history starting in 2026, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the 1.6-litre V6 configuration, boast a significantly increased energy storage, requiring major innovations in the aero packages.

During grand prix events, competitors will strategically manage battery power – including during hot laps – to achieve the optimal result.

Broad surveys were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which phrases would aid comprehension of the main elements of the upcoming rules.

The stated goal was to present a set of intricate technical aspects of the competition as accessible as possible for the broadest viewership.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the adjustable aero – have been abandoned in preference for descriptive names that directly explain the primary purpose of the innovation.

What's the New Technology?

Regulators explain that competitors will have greater control to choose strategies regarding power usage, energy recovery, and efficiency.

The upcoming changes mandate a range of settings that will be clearly indicated on TV overlays to enhance the fans' insight of the race battle.

• Overtake Mode: This supersedes the existing Drag Reduction System. It provides a surge of additional ERS power deployable when a competitor is close behind the vehicle in front to execute an pass.
• Boost Mode: This is a driver-operated battery discharge from the ERS that can be deployed for attack or defence. It grants the pilot full engine and battery energy at the activation of a control.

Both of these key functions will have to be managed carefully, as the overall battery capacity is capped.

• Active Aero: Both the front and rear wings change configuration – opening on the long straight sections for minimal air resistance and higher speed, and sealing in the turns for maximum downforce.
• Battery Recharge: The system can recharge the energy store with energy harvested under braking, or during partial power application at the straight's end or in certain corners where only reduced throttle is applied.

What's Changing on the Cars?

The vehicles for the new era will be reduced in size and weight compared to the 2025 spec, with a wheelbase shortened by 200mm to 3,400mm, overall width cut by 100mm – down to 1,900mm – and the lowest permissible weight reduced by 30kg.

Overall downforce is anticipated to be reduced by approximately 15-30%, although squads will naturally regain performance as they optimize their packages.

Aerodynamic drag has been cut by 40%. The vehicles will feature moveable wing elements – front and rear wings will move on the straights to cut resistance and enhance velocity and revert into place for peak handling.

Wheels will continue to use 18-inch wheel rims, but the tyres themselves will be reduced in width, by 25mm at the front and 30 millimetres on the rear axle.

What's Changing in the Engines?

The revised hybrid units will have an near-equal balance in energy output by the petrol engine and the ERS, a rise from about one-fifth electric power this year.

The energy recovery system is streamlined through the deletion of the MGU-H, the intricate and expensive component that generated electricity from the exhaust turbo.

Every car on the grid will be mandated to operate on fully sustainable fuel, produced using organic sources or lab-created processes.
