Front Wheel Torque Transfer

Chapter: C9

In Simple Terms

F1 cars cannot have a mechanical device that connects the two front wheels together to transfer power between them. This rule ensures both front wheels operate independently and prevents teams from using a linked system that could give an unfair handling advantage.

  • Any mechanical connection between front wheels for torque transfer is banned
  • Front wheels must rotate independently without a locking or linking device
  • This prevents teams from creating advanced differential systems that could unfairly enhance grip or cornering
  • The rule maintains fair competition by standardizing front axle design limitations
Official FIA Text

Any device which is capable of transferring torque between the principal axes of rotation of the two front wheels is prohibited.
