Ducts and Primary Heat Exchangers

In Simple Terms

The cooling ducts and heat exchangers inside an F1 car must be completely hidden from view from any angle looking at the car from the side (perpendicular to the car's length). This is checked with the bodywork in place but before any air openings are added.

• Ducts and primary heat exchangers must be completely concealed from external view
• The rule applies to all perpendicular viewing angles to the X-axis (side views)
• Assessment is done with bodywork present but before apertures (openings) are added
• This maintains F1's aerodynamic and aesthetic regulations
