The world of Formula 1 has unveiled the simplified vocabulary that will be used to describe the technical complexities of its revolutionary 2026 regulations.

The racing series is embarking on what is arguably the biggest regulation change in its illustrious history starting in 2026, featuring revised car and engine specifications and the mandatory use of eco-friendly fuels.

The revised engines, which keep the 1.6-litre V6 configuration, boast a significantly increased energy storage, necessitating major innovations in the vehicles' aerodynamic design.

Throughout races, competitors will strategically manage battery power – sometimes even flying laps – to extract the optimal lap time.

Wide-ranging research were conducted with a mix of viewers, including new, casual and core fans, to understand which terms would aid comprehension of the main elements of the 2026 changes.

The primary aim was to present a series of complex technical aspects of the competition as accessible as possible for the global fanbase.

Consequently, previous placeholder terms for some systems – such as "alphabetical mode names" for the moveable wings – have been abandoned in favour of straightforward terms that succinctly convey the actual function of the system.

Key Technical Innovations

According to rule-makers that competitors will have increased agency to make decisions regarding energy deployment, harvesting, and efficiency.

The 2026 rules mandate a series of modes that will be shown on television graphics to improve the audience's understanding of the race battle.

• Passing Mode: This takes over from the present overtaking aid. It provides a burst of extra electrical energy accessible when a car is within one second the car ahead to facilitate an pass.
• Power Mode: This is a on-demand battery discharge from the ERS that can be utilized during overtaking or defending. It grants the pilot maximum power at the activation of a control.

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

• Adjustable Aero: Both the front and rear wings adjust their angles – spreading on the high-speed sections for minimal air resistance and increased velocity, and angling down in the bends for peak grip.
• Recharge: Cars can recharge the energy store with energy harvested under braking, or during partial power application at the conclusion of a straight or in sections where only partial power is applied.

2026 Car Specifications

The vehicles for the new era will be reduced in size and weight relative to current models, with a distance between axles reduced by 200mm to 3,400mm, overall width reduced by 100mm – down to 1,900mm – and the car weight reduced by 30kg.

Total aerodynamic grip 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 reduced by 40%. The cars will feature active aerodynamics – front and rear wings will open on the straight sections to cut resistance and enhance velocity and click back into place for optimal grip in corners.

Wheels will retain 18-inch rims, but the tyres themselves will be slimmer, by 25 millimetres on the front axle and 30mm at the rear.

2026 Engine Regulations

The 2026 engines will have an approximate 50-50 split in energy output by the ICE and the battery and motor, a rise from about one-fifth electric power this year.

The hybrid system is streamlined through the elimination of the MGU-H, the intricate and expensive unit that harvested power from the turbo.

Cars will be required to run on fully sustainable fuel, produced using plant-based materials or lab-created processes.
