Formula 1 has introduced the simplified language that will be used to explain the technical complexities of its revolutionary 2026 rulebook.

The racing series is embarking on what is potentially the biggest rules overhaul in its competitive history for the 2026 campaign, featuring fresh chassis and power unit regulations and the compulsory introduction of eco-friendly fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the hybrid V6 layout, boast a greatly enhanced electrical capacity, requiring significant developments in the aero packages.

Throughout races, pilots will strategically manage battery power – potentially on qualifying laps – to achieve the optimal performance.

Extensive fan consultation were conducted with a mix of viewers, including dedicated enthusiasts and casual observers, to understand which phrases would improve understanding of the key features of the new regulations.

The primary aim was to present a range of advanced features of the racing as easy to grasp as possible for the widest audience.

Consequently, previous placeholder terms for certain devices – such as "modes labelled X and Z" for the moveable wings – have been phased out in favor of intuitive labels that clearly indicate the primary purpose of the technology.

Exploring the New Tech

According to rule-makers that drivers will have greater control to choose strategies regarding battery management, regeneration, and efficiency.

The upcoming changes introduce a range of settings that will be shown on television graphics to aid the viewers' comprehension of the on-track action.

• Overtake Mode: This takes over from the current DRS. It provides a surge of additional ERS power accessible when a car is within one second the car ahead to execute an overtaking maneuver.
• Boost Mode: This is a driver-operated power boost from the ERS that can be utilized during offensive or defensive moves. It provides the driver full engine and battery energy at the activation of a control.

Both of these crucial modes will have to be used with calculation, as the overall battery capacity is capped.

• Active Aero: Both the front and rear wings change configuration – flattening on the long straight sections for reduced drag and top speed, and closing in the corners for peak grip.
• Battery Recharge: Cars can recharge the energy store with energy harvested under braking, or during coasting at the straight's end or in corners where only reduced throttle is required.

Car Design Evolution

The next-generation machines will be smaller and lighter compared to the 2025 spec, with a distance between axles reduced by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the minimum weight decreased by 30kg.

Total aerodynamic grip is expected to drop by approximately 15-30%, although squads will inevitably claw this back as they develop their cars.

Air resistance has been cut by 40%. The cars will utilize moveable wing elements – front and rear wings will move on the straights to cut resistance and enhance velocity and return into place for optimal grip in corners.

Tyres will continue to use the current rim size, but the rubber compounds will be slimmer, by 25 millimetres on the front axle and three centimetres on the rear.

2026 Engine Regulations

The 2026 engines will have an approximate 50-50 split in horsepower generated by the ICE and the electrical system, a rise from about one-fifth electric power under present rules.

The ERS setup is simplified through the removal of the MGU-H, the complicated and costly component that generated electricity from the turbo.

All vehicles will be mandated to operate on carbon-neutral fuel, created from plant-based materials or synthetic production methods.
