2026 Regulations
The biggest technical shake-up in a generation. New power units, active aerodynamics, sustainable fuels, and lighter, nimbler cars designed to produce closer, more exciting racing.
Power Unit
The heart of the new era
The 1.6-litre V6 turbo hybrid core remains, but the power balance shifts dramatically. The internal combustion engine output drops from ~550kW to ~400kW, while the electric motor triples from 120kW to 350kW — creating a roughly 50/50 power split between petrol and electric.
The expensive and complex Motor Generator Unit-Heat (MGU-H) has been removed. The focus shifts entirely to the MGU-K (kinetic energy recovery), which is technology closer to what's found in road cars — making F1 more relevant to manufacturers.
The Energy Recovery System can now harvest twice as much energy per lap through braking and throttle lift-off at the end of straights. This recovered energy feeds directly into the more powerful battery system, giving drivers a larger electrical reserve.
The simplified power unit architecture has attracted new entries. Audi enters as a full works team with their own power unit, and Red Bull Powertrains supplies both Red Bull Racing and Racing Bulls with their in-house engine.
Active Aerodynamics
DRS is dead. Long live active aero.
The rear wing flaps actively adjust between two positions. On straights, they open to a low-drag mode — flattening the wing to reduce drag and increase top speed. In corners, they close to maximise downforce and grip. Unlike DRS, this happens automatically in designated zones for all drivers.
When within one second of the car ahead, drivers can manually activate an overtake mode that combines the low-drag wing position with extra electrical energy from the battery — giving a significant speed boost for attacking or defending. Usable anywhere on track.
X-Mode is the low-downforce, low-drag configuration used on straights — wings flatten out for maximum speed. Z-Mode is the high-downforce configuration for corners — wings at maximum angle for grip. The car transitions between these automatically based on track position.
Overall drag is reduced by up to 40%, making the cars significantly faster on straights. Combined with the electrical overtake boost, this is designed to produce more wheel-to-wheel battles and more varied race strategies.
Car Design
Shorter, narrower, lighter, faster
Gone are the long ground-effect tunnels of the 2022–2025 era. The 2026 cars feature flatter floors with extended diffusers, combined with a higher minimum ride height. This reduces the reliance on ground effect and shifts the aerodynamic philosophy.
Narrower front wing elements with new outer sections create fresh areas for aerodynamic development. Rear beam wings have been eliminated entirely, and the overall bodywork is more compact to suit the shorter, narrower chassis.
Sustainable Fuel
Zero new fossil carbon
From 2026, every car runs on fully sustainable fuel with no new fossil carbon being burned. The carbon in the fuel is derived from non-food sources, genuine municipal waste, or captured directly from the atmosphere. F1 aims for the transition to be seamless — "success will be measured by nobody noticing."
The development of advanced sustainable fuels at F1 performance levels drives innovation that feeds directly into road car fuel technology. Combined with the tripled electric power output, the 2026 power units are a showcase for the future of high-performance sustainable mobility.
Safety
Stronger, smarter protection
The roll hoop structure must now withstand 23% more force, significantly improving protection in rollover incidents.
The front impact structure now separates in two stages, progressively absorbing energy for better crash protection.
The survival cell undergoes more rigorous crash tests than ever before, ensuring the highest level of driver protection.
