F1 has unveiled the official language that will be used to reference the technical complexities of its upcoming 2026 regulations.

The racing series is introducing what is potentially the biggest regulation change in its competitive history starting in 2026, featuring revised car and engine specifications and the mandatory use of eco-friendly fuels.

The revised engines, which retain the 1.6-litre V6 turbo hybrid, boast a significantly increased energy storage, driving major innovations in the cars' aerodynamics.

During grand prix events, pilots will strategically manage ERS energy – including during flying laps – to extract the peak performance.

Broad surveys were carried out with a diverse audience, including long-time followers and newcomers, to determine which terms would aid comprehension of the key features of the 2026 changes.

The primary aim was to make a series of complex features of the sport as accessible as possible for the global fanbase.

Consequently, older technical labels for some systems – such as "modes labelled X and Z" for the adjustable aero – have been abandoned in preference for intuitive labels that succinctly convey the actual function of the system.

Exploring the New Tech

Regulators explain that drivers will have more power to determine tactics regarding battery management, harvesting, and efficiency.

The new regulations mandate a range of settings that will be clearly indicated on television graphics to improve the fans' insight of the race battle.

• Attack Mode: This takes over from the current DRS. It provides a burst of extra electrical energy accessible when a competitor is less than a second the vehicle in front to assist with an overtake.
• Power Mode: This is a on-demand battery discharge from the hybrid system that can be used in attack or defence. It grants the pilot maximum power at the activation of a control.

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

• Active Aerodynamics: Both the nose and rear wings adjust their angles – opening on the long straight sections for low aerodynamic resistance and top speed, and sealing in the turns for peak grip.
• Battery Recharge: Cars can harvest energy with regenerative braking, or during partial power application at the conclusion of a straight or in sections where only limited engine output is used.

Car Design Evolution

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

Cumulative downforce is projected to decrease by approximately 15-30%, although teams will inevitably claw this back as they refine their designs.

Air resistance has been slashed by 40%. The vehicles will utilize adjustable aero systems – both wings will open on the straights to reduce drag and boost top speed and revert into place for optimal grip in corners.

Wheels will continue to use 18-inch rims, but the rubber compounds will be narrower, by 25mm at the front and 30mm at the rear.

Power Unit Revolution

The revised hybrid units will have an approximate 50-50 split in horsepower generated by the ICE and the battery and motor, up from about 20% battery contribution this year.

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

All vehicles will be mandated to operate on 100% sustainable fuel, manufactured from plant-based materials or synthetic industrial processes.
