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

The racing series is embarking on what is considered the biggest rules overhaul in its competitive history for the 2026 campaign, featuring new chassis and engine rules and the mandatory use of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the 1.6-litre V6 configuration, boast a significantly increased electrical capacity, driving significant developments in the aero packages.

Over a race distance, pilots will tactically deploy ERS energy – including during flying laps – to secure the best lap time.

Broad surveys were carried out with a diverse audience, including new, casual and core fans, to understand which terms would improve understanding of the key features of the new regulations.

The stated goal was to present a series of complex features of the competition as easy to grasp as possible for the global fanbase.

Consequently, initial designations for specific components – such as "modes labelled X and Z" for the adjustable aero – have been discarded in preference for descriptive names that directly explain the actual function of the technology.

Key Technical Innovations

Regulators explain that racers will have more power to make decisions regarding battery management, regeneration, and conservation.

The upcoming changes introduce a set of functions that will be clearly indicated on broadcast screens to enhance the viewers' comprehension of the on-track action.

• Attack Mode: This supersedes the present overtaking aid. It provides a surge of additional ERS power accessible when a competitor is less than a second the car ahead to facilitate an overtaking maneuver.
• Extra Push Mode: This is a on-demand power boost from the ERS that can be utilized during overtaking or defending. It provides the pilot maximum power at the push of a button.

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

• Active Aero: Both the nose and rear wings adjust their angles – spreading on the long straight sections for reduced drag and increased velocity, and sealing in the bends for maximum downforce.
• Recharge: Cars can recharge the energy store 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 vehicles for the new era will be reduced in size and weight than this year, with a car length cut 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 fifteen to thirty percent, although teams will inevitably claw this back as they refine their designs.

Drag has been slashed by 40%. The cars will utilize moveable wing elements – both wings will open on the straights to improve speed and enhance velocity and return into place for peak handling.

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

2026 Engine Regulations

The new power units will have an roughly half-and-half distribution in horsepower generated by the ICE and the battery and motor, up from about 20% electrical in the current formula.

The energy recovery system is simplified through the deletion of the MGU-H, the sophisticated and pricey device that recovered energy from the turbo.

Every car on the grid will be required to run on carbon-neutral fuel, produced using organic sources or synthetic production methods.
