EC Louvre Cooling Aperture

In Simple Terms

Teams can have a louvre-style cooling opening on the engine cover to help dissipate heat, but it's limited to a maximum size of 150,000mm² and can only allow air to flow outward. When viewed from directly above, the rear louvre must be completely hidden from sight, and teams cannot move or shift its position.

• Maximum cooling aperture area is 150,000mm² (roughly 40cm x 40cm)
• Louvre opening must be for cooling airflow only (efflux direction)
• Rear louvre must be fully obscured when viewed from above - no visible gaps
• Fixed position - the aperture cannot be moved or adjusted
