The world of Formula 1 has unveiled the official vocabulary that will be used to reference the technical complexities of its upcoming 2026 technical rules.

The racing series is embarking on what is arguably the biggest technical shift in its illustrious history starting in 2026, featuring fresh chassis and power unit regulations and the mandatory use of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the 1.6-litre V6 turbo hybrid, boast a substantially higher battery power, requiring significant developments in the cars' aerodynamics.

During grand prix events, pilots will carefully oversee ERS energy – sometimes even qualifying laps – to achieve the best lap time.

Broad surveys were carried out with a wide range of fans, including new, casual and core fans, to determine which phrases would improve understanding of the key features of the new regulations.

The stated goal was to present a series of complex technical aspects of the racing as accessible as possible for the global fanbase.

Consequently, initial designations for certain devices – such as "alphabetical mode names" for the moveable wings – have been discarded in preference for intuitive labels that directly explain the real-world effect of the innovation.

Key Technical Innovations

Regulators explain that racers will have greater control to choose strategies regarding battery management, regeneration, and efficiency.

The 2026 rules mandate a set of functions that will be clearly indicated on broadcast screens to aid the viewers' comprehension of the race battle.

• Passing Mode: This supersedes the present overtaking aid. It provides a burst of extra electrical energy accessible when a driver is less than a second the vehicle in front to facilitate an overtake.
• Extra Push Mode: This is a driver-operated power boost from the energy recovery system that can be utilized during overtaking or defending. It provides the pilot peak output at the click of a switch.

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

• Active Aero: Both the nose and rear wings move automatically – opening on the straights for low aerodynamic resistance and higher speed, and sealing in the bends for optimal cornering performance.
• Battery Recharge: Cars can replenish their battery with power recovered from braking, or during coasting at the end of straights or in sections where only reduced throttle is required.

What's Changing on the Cars?

The vehicles for the new era will be more compact and lighter relative to current models, with a distance between axles cut by 200mm to 3,400mm, overall width narrowed by 100mm – down to 1,900mm – and the lowest permissible weight lowered by 30kg.

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

Aerodynamic drag has been cut by 40%. The vehicles will utilize moveable wing elements – front and rear wings will adjust on the straight sections to cut resistance and increase straightline speed and click back into place for optimal grip in corners.

Pirelli tyres will continue to use 18-inch wheel rims, but the tyres themselves will be narrower, by a quarter-centimetre on the front and three centimetres on the rear.

Power Unit Revolution

The 2026 engines will have an roughly half-and-half distribution in horsepower generated by the petrol engine and the ERS, a rise from about one-fifth electric power under present rules.

The hybrid system is simplified through the elimination of the complex turbo energy recovery device, the complicated and costly unit that generated electricity from the turbocharger.

Cars will be obliged to compete on carbon-neutral fuel, produced using biomass or lab-created processes.
