Formula 1 has introduced the new language that will be used to describe the intricate details of its revolutionary 2026 technical rules.

The championship is implementing what is arguably the most significant regulation change in its illustrious history next season, featuring revised car and engine specifications and the required adoption of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which maintain the hybrid V6 layout, boast a significantly increased energy storage, necessitating major innovations in the vehicles' aerodynamic design.

Over a race distance, drivers will strategically manage electrical energy – sometimes even qualifying laps – to extract the best lap time.

Broad surveys were carried out with a mix of viewers, including dedicated enthusiasts and casual observers, to determine which terms would aid comprehension of the main elements of the new regulations.

The primary aim was to present a range of advanced new areas of the sport as straightforward as possible for the broadest viewership.

Consequently, older technical labels for some systems – such as "modes labelled X and Z" for the moveable wings – have been discarded in preference for descriptive names that succinctly convey the actual function of the innovation.

Key Technical Innovations

The FIA states that drivers will have greater control to determine tactics regarding power usage, harvesting, and conservation.

The new regulations feature a range of settings that will be clearly indicated on TV overlays to improve the fans' insight of the race battle.

• Overtake Mode: This supersedes the present overtaking aid. It provides a surge of additional ERS power available when a driver is less than a second the car ahead to assist with an overtaking maneuver.
• Boost Mode: This is a manual energy deployment from the ERS that can be utilized during offensive or defensive moves. It delivers the pilot maximum power at the click of a switch.

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

• Adjustable Aero: Both the nose and rear wings adjust their angles – spreading on the straights for low aerodynamic resistance and top speed, and angling down in the turns for maximum downforce.
• Recharge: Cars can harvest energy with power recovered from braking, or during coasting at the straight's end or in corners where only limited engine output is used.

What's Changing on the Cars?

The 2026 cars will be more compact and lighter compared to the 2025 spec, with a wheelbase reduced by 200mm to 3,400mm, car width reduced by 100mm – down to 1,900mm – and the lowest permissible weight lowered by 30kg.

Total aerodynamic grip is expected to drop by approximately a significant margin, although squads will naturally regain performance as they refine their designs.

Drag has been cut by 40%. The cars will employ adjustable aero systems – front and rear wings will adjust on the straight sections to cut resistance and increase straightline speed and return into place for optimal grip in corners.

Tyres will retain 18-inch wheel rims, but the actual tyres will be reduced in width, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The revised hybrid units will have an near-equal balance in energy output by the ICE and the electrical system, a rise from about 20% electrical under present rules.

The energy recovery system is made less complex through the deletion of the MGU-H, the sophisticated and pricey unit that recovered energy from the turbo.

Every car on the grid will be obliged to compete on fully sustainable fuel, created from organic sources or lab-created processes.
