F1 has revealed the simplified vocabulary that will be used to describe the intricate details of its upcoming 2026 technical rules.

The sport is embarking on what is considered the biggest technical shift in its illustrious history next season, featuring new chassis and engine rules and the mandatory use of fully sustainable fuels.

The new power units, which retain the hybrid V6 layout, boast a significantly increased battery power, driving significant developments in the aero packages.

During grand prix events, drivers will tactically deploy ERS energy – potentially on qualifying laps – to extract the peak lap time.

Broad surveys were carried out with a diverse audience, including long-time followers and newcomers, to determine which terms would improve understanding of the key features of the upcoming rules.

The stated goal was to present a range of advanced new areas of the sport as easy to grasp as possible for the global fanbase.

Consequently, previous placeholder terms for specific components – such as "alphabetical mode names" for the moveable wings – have been phased out in favour of intuitive labels that directly explain the actual function of the innovation.

Exploring the New Tech

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

The 2026 rules mandate a range of settings that will be visually displayed on broadcast screens to improve the fans' insight of the strategic duel.

• Overtake Mode: This supersedes the current DRS. It provides a short boost of battery power deployable when a competitor is within one second the leading car to assist with an overtake.
• Power Mode: This is a driver-operated energy deployment from the hybrid system that can be deployed for attack or defence. It grants the pilot peak output at the click of a switch.

Both of these crucial modes will have to be used with calculation, as the available electrical charge is restricted.

• Active Aerodynamics: Both the car's wings change configuration – opening on the straights for low aerodynamic resistance and increased velocity, and sealing in the corners for peak grip.
• Recharge: Drivers can harvest energy with power recovered from braking, or during throttle lift at the end of straights or in corners where only reduced throttle is used.

2026 Car Specifications

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

Overall downforce is anticipated to be reduced by approximately a significant margin, although constructors will naturally regain performance as they optimize their packages.

Drag has been slashed by 40%. The vehicles will feature adjustable aero systems – both wings will adjust on the straights to improve speed and enhance velocity and return into place for peak handling.

Tyres will continue to use 18-inch rims, but the actual tyres will be narrower, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The 2026 engines will have an near-equal balance in horsepower generated by the petrol engine and the battery and motor, a rise from about 20% battery contribution under present rules.

The hybrid system is simplified through the deletion of the complex turbo energy recovery device, the intricate and expensive component that harvested power from the turbo.

All vehicles will be required to run on 100% sustainable fuel, produced using plant-based materials or lab-created processes.
