The world of Formula 1 has introduced the new language that will be used to explain the advanced features of its revolutionary 2026 regulations.

The championship is implementing what is arguably the largest technical shift in its long history for the 2026 campaign, featuring new chassis and engine rules and the required adoption of fully sustainable fuels.

The updated 1.6-litre V6 turbo hybrids, which retain the 1.6-litre V6 configuration, boast a greatly enhanced energy storage, requiring significant developments in the vehicles' aerodynamic design.

Throughout races, drivers will strategically manage ERS energy – sometimes even flying laps – to achieve the optimal lap time.

Extensive fan consultation were undertaken with a mix of viewers, including new, casual and core fans, to determine which phrases would aid comprehension of the key features of the 2026 changes.

The key objective was to present a range of advanced features of the sport as straightforward as possible for the global fanbase.

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 clearly indicate the real-world effect of the system.

Exploring the New Tech

According to rule-makers that drivers will have greater control to choose strategies regarding battery management, harvesting, and efficiency.

The 2026 rules mandate a set of functions that will be clearly indicated on broadcast screens to enhance the fans' insight of the on-track action.

• Attack Mode: This replaces the current DRS. It provides a surge of additional ERS power available when a competitor is within one second the leading car to execute an overtake.
• Boost Mode: This is a manual battery discharge from the ERS that can be used in attack or defence. It delivers the driver maximum power at the click of a switch.

Both of these key functions will have to be used with calculation, as the total energy is capped.

• Active Aerodynamics: Both the front and rear wings adjust their angles – spreading on the high-speed sections for reduced drag and higher speed, and sealing in the corners for optimal cornering performance.
• Battery Recharge: Cars can harvest energy with power recovered from braking, or during coasting at the conclusion of a straight or in sections where only partial power is required.

2026 Car Specifications

The vehicles for the new era will be more compact and lighter compared to the 2025 spec, with a wheelbase shortened by 200mm to 3,400mm, car width cut by 100mm – down to 1,900mm – and the car weight decreased by 30kg.

Total aerodynamic grip is projected to decrease by approximately a significant margin, although constructors will inevitably claw this back as they optimize their packages.

Drag has been reduced by 40%. The vehicles will utilize active aerodynamics – front and rear wings will move on the straights to cut resistance and enhance velocity and click back into place for optimal grip in corners.

Wheels will retain the current rim size, but the actual tyres will be reduced in width, by a quarter-centimetre on the front and 30 millimetres on the rear axle.

What's Changing in the Engines?

The revised hybrid units will have an roughly half-and-half distribution in energy output by the petrol engine and the electrical system, up from about 20% battery contribution in the current formula.

The hybrid system is made less complex through the removal of the complex turbo energy recovery device, the intricate and expensive component that generated electricity from the turbocharger.

All vehicles will be mandated to operate on 100% sustainable fuel, created from organic sources or lab-created processes.
