F1 has unveiled the simplified terminology that will be used to describe the intricate details of its upcoming 2026 rulebook.

The racing series is implementing what is considered the largest rules overhaul in its illustrious history for the 2026 campaign, featuring revised car and engine specifications and the mandatory use of 100% sustainable fuels.

The new power units, which retain the 1.6-litre V6 configuration, boast a greatly enhanced battery power, requiring key advancements in the aero packages.

Throughout races, drivers will strategically manage electrical energy – sometimes even qualifying laps – to extract the optimal result.

Broad surveys were undertaken with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which terminology would improve understanding of the key features of the 2026 changes.

The key objective was to present a range of advanced features of the competition as easy to grasp as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "modes labelled X and Z" for the adjustable aero – have been abandoned in preference for straightforward terms that clearly indicate the actual function of the technology.

Key Technical Innovations

According to rule-makers that competitors will have more power to determine tactics regarding energy deployment, harvesting, and conservation.

The upcoming changes introduce a set of functions that will be shown on broadcast screens to improve the fans' insight of the race battle.

• Attack Mode: This replaces the present overtaking aid. It provides a short boost of battery power deployable when a competitor is close behind the leading car to execute an overtaking maneuver.
• Power Mode: This is a driver-operated energy deployment from the energy recovery system that can be utilized during overtaking or defending. It delivers the driver peak output at the push of a button.

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

• Active Aero: Both the car's wings adjust their angles – opening on the long straight sections for minimal air resistance and increased velocity, and angling down in the bends for optimal cornering performance.
• Battery Recharge: Cars can recharge the energy store with power recovered from braking, or during partial power application at the straight's end or in sections where only reduced throttle is applied.

Car Design Evolution

The next-generation machines will be reduced in size and weight compared to the 2025 spec, with a wheelbase cut by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight reduced by 30kg.

Cumulative downforce is expected to drop by approximately fifteen to thirty percent, although teams will inevitably claw this back as they optimize their packages.

Drag has been reduced by 40%. The vehicles will employ adjustable aero systems – both wings will adjust on the straight sections to improve speed and boost top speed and revert into place for peak handling.

Wheels will keep the current rim size, but the actual tyres will be slimmer, by 25mm at the front and three centimetres on the rear.

Power Unit Revolution

The 2026 engines will have an roughly half-and-half distribution in power produced by the petrol engine and the electrical system, a rise from about 20% battery contribution under present rules.

The ERS setup is simplified through the removal of the MGU-H, the sophisticated and pricey device that harvested power from the exhaust turbo.

All vehicles will be mandated to operate on carbon-neutral fuel, produced using plant-based materials or lab-created processes.
