F1 2026 regulations: Explaining changes to aero, chassis and engine rules
A detailed look at the 2026 F1 regulations

F1's new era in 2026 is taking shape with a number of s🥀ignificant changes to the aerodynamic, ch✤assis and engines.
The new regulations are centred around making the new cars more “nimble” while making them better in wheel-t🌃o-wheel combat.
The changes on the engine side of the rules have attracted a nꦑumber of ಌmanufacturers.
168澳洲幸运5官方开奖结果历史:Mercedes and Ferrari remain in the sport, while Red Bull ar♕e building their own power unit🔯 for the first time in collaboration with Ford.
Renault will also continue to race in F1 via their Alpine bra🍰nd, but will abandon thei🎀r long-running engine programme to become a Mercedes customer.
Honda are making 🙈their return with Aston Martin, while Audi are coming in as fully-fledged manufacturers, taking over the Sauber outfit.
Cadillac join as the 11th team on the g🅷rid with customer ไFerrari engines, but will have their own in-house engine programme before the end of the decade.
Here’s a run down of the key rules for 2026...
Power unit
The major change on the power unit side comes wi꧒th a 300 per cent increase in electrical power coming from the battery alone. The power unit has also been simplified with the removal of the ൲MGU-H and aforementioned expansion of electrical power.
They will be ꦺrun on 100 per cent sustainable fuels.
Other key changes include:
- Amount of energy recuperated during braking has been doubled to 8.5mj per lap.
- Addition of a ‘Manual Override Mode’ to help improve overtaking opportunities.
Chassis
As previously mentioned, the FIA’s ꦛtechnical 🌼group have focused on making the cars more nimble.
This means the following changes have been mad🎉e for 2026:
- The wheelbase drops from a maximum of 3600mm to 3400mm, while the width has been reduced from 2000mm to 1900mm. The maximum floor width will be reduced by 150mm.
- Weight reduced by 30kg. A minimum weight of 768kg in total.
- Downforce has been reduced by 30 per cent; drag by 55 per cent.
- 18-inch wheels remain. Width of the front tyres reduced by 25mm; rears by 30mm.
Aerodynamics
Acti💝ve aerodynamics makes a return to F1 with a new system in place which looks to replace DRS and thus improve wheel-to-wheel racing.
In essence, drivers will be able to adjust their front and wear wings to potentially maximise straight-line sp🐲eed by switching to ‘X-Mode’. ‘Z-Mode’ will be deployed through corners.
Other changes include:
- A three-element active rear wing, with the lower beam wing removed, while the end plates have been simplified.
- The front wing is made 100 mm narrower than the current generation.
- Front wheel arches will be removed and some of the wheel bodywork mandated.
- A return to a partial flat floor and lower-powered diffuser. This will reduce ground effect.
Safety
Unsurprisingly, the FIA’s p🌌ursuit of improving safety s🎉tandards hasn’t stopped.
Significant changes a𒁏re being made to front impact regulations with the introduction of a two-stage structure.
Other safety advancements noted by the FIA are:
- Side intrusion protection has also been increased to give better protection of the side fuel cells.
- Further adjustments cover roll hool loads being upped from 16G to 20G.
- Rear wing endplate lights will be homologated and significantly more visible.
- GPS antenna repositioned to improve sensitivity and more scope to improve safety
