The world of Formula 1 has unveiled the official vocabulary that will be used to explain the intricate details of its revolutionary 2026 rulebook.

The racing series is introducing what is arguably the largest regulation change in its illustrious history next season, featuring fresh chassis and power unit regulations and the required adoption of eco-friendly fuels.

The revised engines, which maintain the hybrid V6 layout, boast a greatly enhanced energy storage, driving significant developments in the aero packages.

Throughout races, pilots will carefully oversee electrical energy – potentially on qualifying laps – to secure the peak performance.

Wide-ranging research were undertaken with a wide range of fans, including long-time followers and newcomers, to understand which phrases would improve understanding of the main elements of the upcoming rules.

The key objective was to render a range of advanced new areas of the competition as easy to grasp as possible for the broadest viewership.

Consequently, initial designations for specific components – such as "alphabetical mode names" for the active aerodynamics – have been phased out in preference for descriptive names that directly explain the actual function of the system.

Exploring the New Tech

The FIA states that racers will have greater control to determine tactics regarding battery management, energy recovery, and conservation.

The 2026 rules introduce a set of functions that will be visually displayed on broadcast screens to enhance the viewers' comprehension of the race battle.

• Overtake Mode: This supersedes the current DRS. It provides a short boost of battery power deployable when a competitor is close behind the leading car to execute an overtaking maneuver.
• Extra Push Mode: This is a driver-operated power boost from the energy recovery system that can be used in attack or defence. It provides the driver full engine and battery energy at the push of a button.

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

• Adjustable Aero: Both the nose and rear wings move automatically – spreading on the high-speed sections for minimal air resistance and higher speed, and angling down in the turns for maximum downforce.
• Recharge: The system can harvest energy with power recovered from braking, or during partial power application at the end of straights or in sections where only limited engine output is applied.

2026 Car Specifications

The 2026 cars will be reduced in size and weight compared to the 2025 spec, with a car length shortened by 200mm to 3,400mm, width narrowed by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Cumulative downforce is expected to drop by approximately a significant margin, although constructors will inevitably claw this back as they refine their designs.

Aerodynamic drag has been slashed by 40%. The cars will feature moveable wing elements – front and rear wings will adjust on the straights to reduce drag and increase straightline speed and return into place for optimal grip in corners.

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

What's Changing in the Engines?

The revised hybrid units will have an near-equal balance in horsepower generated by the internal combustion engine and the ERS, up from about 20% electrical in the current formula.

The ERS setup is simplified through the elimination of the complex turbo energy recovery device, the intricate and expensive device that recovered energy from the turbo.

Cars will be mandated to operate on fully sustainable fuel, produced using organic sources or lab-created processes.
