The world of Formula 1 has introduced the official language that will be used to explain the advanced features of its revolutionary 2026 regulations.

The championship is embarking on what is considered the most significant technical shift in its long history next season, featuring fresh chassis and power unit regulations and the compulsory introduction of fully sustainable fuels.

The new power units, which retain the 1.6-litre V6 turbo hybrid, boast a significantly increased energy storage, driving major innovations in the vehicles' aerodynamic design.

During grand prix events, drivers will strategically manage ERS energy – sometimes even hot laps – to secure the peak lap time.

Wide-ranging research were carried out with a mix of viewers, including new, casual and core fans, to identify which terms would make things clearer of the main elements of the new regulations.

The primary aim was to render a set of intricate features of the competition as straightforward as possible for the widest audience.

Consequently, older technical labels for certain devices – such as "alphabetical mode names" for the adjustable aero – have been phased out in favour of descriptive names that succinctly convey the primary purpose of the innovation.

What's the New Technology?

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

The 2026 rules mandate a series of modes that will be clearly indicated on broadcast screens to enhance the fans' insight of the race battle.

• Attack Mode: This takes over from the existing Drag Reduction System. It provides a surge of additional ERS power deployable when a car is less than a second the car ahead to assist with an pass.
• Boost Mode: This is a manual energy deployment from the hybrid system that can be utilized during attack or defence. It delivers the pilot peak output at the click of a switch.

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

• Active Aerodynamics: Both the front and rear wings change configuration – spreading on the long straight sections for reduced drag and increased velocity, and sealing in the corners for optimal cornering performance.
• Energy Harvesting: The system can harvest energy with energy harvested under braking, or during coasting at the straight's end or in sections where only partial power is used.

Car Design Evolution

The vehicles for the new era will be more compact and lighter than this year, with a distance between axles shortened by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Overall downforce is projected to decrease by approximately fifteen to thirty percent, although teams will inevitably claw this back as they optimize their packages.

Drag has been cut by 40%. The vehicles will feature active aerodynamics – both wings will adjust on the straight sections to improve speed and increase straightline speed and return into place for optimal grip in corners.

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

Power Unit Revolution

The 2026 engines will have an roughly half-and-half distribution in energy output by the internal combustion engine and the ERS, a rise from about one-fifth electric power this year.

The hybrid system is streamlined through the elimination of the Motor Generator Unit – Heat, the intricate and expensive unit that harvested power from the exhaust turbo.

All vehicles will be mandated to operate on carbon-neutral fuel, manufactured from biomass or synthetic production methods.
