Wind tunnel and CFD limits: the aerodynamic testing handicap

Aero testing allowances scale with championship position. Here is how the sliding scale works. Upgrades are rarely a single part. A new floor edge can require changes to the sidepods, the beam wing and the suspension fairings.

The sliding scale

Wind tunnel time and CFD runs are limited, with less allowed for teams higher in the championship.

Power units combine a turbocharged V6 with energy recovery systems that harvest under braking and from exhaust heat.

FormulaKite editorial note

Tunnel versus CFD

Reliability is designed in from the start: every gram saved has to be balanced against the risk of a failure on track.

• Aerodynamics is the key factor in this section.
• Regulations explains most of the remaining differences.
• Context from previous seasons helps judge how unusual it is.

Does it close the gap

Modern Formula 1 cars generate most of their downforce from the floor, using shaped tunnels to accelerate air beneath the car.

Upgrades are rarely a single part. A new floor edge can require changes to the sidepods, the beam wing and the suspension fairings.
