Formula 1 has introduced the simplified terminology that will be used to reference the intricate details of its revolutionary 2026 technical rules.

The championship is embarking on what is arguably the biggest rules overhaul in its competitive history next season, featuring new chassis and engine rules and the compulsory introduction of 100% sustainable fuels.

The new power units, which keep the 1.6-litre V6 turbo hybrid, boast a greatly enhanced electrical capacity, requiring major innovations in the cars' aerodynamics.

Throughout races, pilots will strategically manage ERS energy – sometimes even qualifying laps – to extract the optimal lap time.

Extensive fan consultation were conducted with a wide range of fans, including new, casual and core fans, to identify which terms would make things clearer of the central aspects of the new regulations.

The primary aim was to render a set of intricate features of the racing as accessible as possible for the broadest viewership.

Consequently, older technical labels for some systems – such as "modes labelled X and Z" for the active aerodynamics – have been phased out in favour of intuitive labels that succinctly convey the real-world effect of the innovation.

Exploring the New Tech

Regulators explain that competitors will have greater control to choose strategies regarding battery management, energy recovery, and efficiency.

The new regulations feature a series of modes that will be clearly indicated on TV overlays to enhance the viewers' comprehension of the race battle.

• Passing Mode: This takes over from the present overtaking aid. It provides a short boost of battery power deployable when a driver is close behind the vehicle in front to facilitate an overtake.
• Boost Mode: This is a on-demand battery discharge from the hybrid system that can be used in attack or defence. It delivers the driver full engine and battery energy at the activation of a control.

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

• Active Aero: Both the nose and rear wings change configuration – flattening on the straights for reduced drag and higher speed, and angling down in the turns for maximum downforce.
• Recharge: Drivers can harvest energy with regenerative braking, or during coasting at the conclusion of a straight or in certain corners where only reduced throttle is applied.

2026 Car Specifications

The vehicles for the new era will be more compact and lighter relative to current models, with a car length reduced by 200mm to 3,400mm, width cut by 100mm – down to 1,900mm – and the lowest permissible weight decreased by 30kg.

Cumulative downforce is anticipated to be reduced by approximately fifteen to thirty percent, although squads will undoubtedly recover some as they develop their cars.

Drag has been slashed by 40%. The vehicles will employ moveable wing elements – both wings will adjust on the straights to cut resistance and boost top speed and return into place for maximum cornering performance.

Pirelli tyres will retain 18-inch wheel rims, but the tyres themselves will be slimmer, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

2026 Engine Regulations

The new power units will have an near-equal balance in power produced by the internal combustion engine and the ERS, increasing from about 20% electrical under present rules.

The energy recovery system is made less complex through the elimination of the complex turbo energy recovery device, the sophisticated and pricey component that harvested power from the turbo.

Cars will be obliged to compete on carbon-neutral fuel, created from organic sources or synthetic production methods.
