What is the sliding scale for wind tunnel testing?

The wind tunnel testing sliding scale in Formula 1 limits how much aerodynamic development teams can do. It is designed to balance development among teams and encourage cost control.

Teams are allocated a maximum number of wind tunnel testing hours based on their overall performance in the previous season. Better-performing teams have stricter limits, while new or smaller teams have more flexibility.

  • The sliding scale adjusts maximum testing hours according to team ranking and budget cap compliance.
  • It ensures that top teams cannot dominate development by excessive wind tunnel use.
  • The scale varies depending on the team’s performance and whether they meet the cost cap rules.
  • Adjustments are reviewed annually by the FIA based on previous year's competitiveness and regulations.

This system promotes fair competition by limiting aerodynamic testing and encouraging innovation within regulated limits.
