Article C5.3.3
Turbocharger shaft axis orientation
Chapter: C5
In Simple Terms
The turbocharger shaft must be oriented in a very specific way: it needs to point along the car's length (parallel to the centerline) and sit toward the inside of the engine bay. The shaft can only tilt up to 1 degree from perfect alignment with the car's direction.
- The turbocharger shaft must be parallel to the car's centerline (Y=0)
- The shaft must be positioned inboard (toward the center) of the Y=25 measurement line
- The shaft can only deviate 0 ±1 degree from the car's lengthwise axis (X-axis)
- This strict alignment ensures standardized turbocharger positioning across all F1 cars
Official FIA Text
The axis of the turbocharger shaft must be parallel to Y=0, inboard of Y=25 and at an angle of 0 +/- 1 degree to X=axis.
