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

The championship is embarking on what is potentially the largest technical shift in its competitive history starting in 2026, featuring new chassis and engine rules and the mandatory use of 100% sustainable fuels.

The new power units, which keep the 1.6-litre V6 configuration, boast a substantially higher energy storage, necessitating significant developments in the cars' aerodynamics.

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

Wide-ranging research were carried out with a mix of viewers, including long-time followers and newcomers, to understand which terms would aid comprehension of the key features of the new regulations.

The primary aim was to render a series of complex features of the sport 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 active aerodynamics – have been phased out in favor of straightforward terms that succinctly convey the actual function of the innovation.

Exploring the New Tech

The FIA states that competitors will have greater control to make decisions regarding power usage, energy recovery, and efficiency.

The new regulations feature a set of functions that will be shown on broadcast screens to aid the viewers' comprehension of the on-track action.

• Passing Mode: This replaces the current DRS. It provides a short boost of battery power accessible when a competitor is close behind the vehicle in front to facilitate an overtaking maneuver.
• Boost Mode: This is a manual energy deployment from the hybrid system that can be utilized during offensive or defensive moves. It grants the driver full engine and battery energy at the activation of a control.

Both of these crucial modes will have to be deployed strategically, as the total energy is capped.

• Active Aero: Both the front and rear wings change configuration – opening on the straights for low aerodynamic resistance and higher speed, and closing in the bends for peak grip.
• Recharge: Drivers can harvest energy with regenerative braking, or during throttle lift at the end of straights or in certain corners where only limited engine output is applied.

Car Design Evolution

The 2026 cars will be smaller and lighter relative to current models, with a wheelbase shortened by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the lowest permissible weight reduced by 30kg.

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

Drag has been slashed by 40%. The vehicles will utilize adjustable aero systems – both wings will move on the straight sections to improve speed and enhance velocity and revert into place for optimal grip in corners.

Pirelli tyres will retain 18-inch rims, but the tyres themselves will be slimmer, by 25mm at the front and three centimetres on the rear.

What's Changing in the Engines?

The revised hybrid units will have an roughly half-and-half distribution in horsepower generated by the internal combustion engine and the battery and motor, a rise from about 20% electrical this year.

The ERS setup 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 mandated to operate on carbon-neutral fuel, created from organic sources or lab-created processes.
