𓆏F1's new era in 2026 is taking shape with a number of signific🌄ant changes to the aerodynamic, chassis and engines.

The new regulations are centred around making the new cars mor🍷e “nimble” while making them better in🧸 wheel-to-wheel combat.

The changes o꧟n the engine side of the rules hav🃏e attracted a number of manufacturers.

168澳洲5最新开奖结果:Mercedes and Ferrari r🉐emain in the sport, while Red Bull are building their own power unit for the first time in collaboration with Ford.

Renault will also continue to race in F1 via their Alpine brand, but will a💛bandon their long-running engine programme to bec🔯ome a Mercedes customer.

Honda are making 🍨their return with Aston Martin, while Audi are coming in as fully-fledged manufacturers, taking ov෴er the Sauber outfit.

Cadillac join as the 11th team on the grid🅺 with customer Ferrari 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 with a 300 per cent increase in electrical power coming from the battery alone. The po𓂃wer unit has also been simplified with the removal of 🦹the MGU-H and aforementioned expansion of electrical power.

They will be run on 100 per cent susꦆtainable 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 technical group have focused on makiꦆng tꦉhe cars more nimble.

Tꦿhis means the followin🌳g changes have been made 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

Active aerodynamics makes𒁃 a return to F1 with a new system in place which looks 𝓀to 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-line𒉰 speed 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 pursuit of improving safet▨y sta♐ndards hasn’t stopped.

Significant changes are being mꦫade 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
