Article C5.3.2
Engine intake air pressure
Chapter: C5
In Simple Terms
F1 teams must ensure that the air pressure entering their engine stays below 4.8 barA (a unit of atmospheric pressure) at all times. To verify this, two official FIA-sealed pressure measuring devices monitor all the air flowing into the engine for combustion.
- Maximum air intake pressure is strictly limited to less than 4.8 barA
- Two independent FIA-approved and sealed devices must measure the pressure
- All combustion air must pass through these measuring devices
- This prevents teams from artificially boosting engine performance through excessive air pressure
Official FIA Text
Engine intake air pressure must be less than 4.8 barA at all times. The pressure of the air will be measured by two FIA approved and sealed devices through which all air destined for combustion must flow.
