Coordinate systems and conventions

Chapter: ARTICLE C2: CONVENTIONS AND FUNDAMENTAL DIMENSIONS

In Simple Terms

F1 uses a standardized 3D coordinate system to measure and define car dimensions and component positions. Think of it like a GPS grid on the car itself: the X-axis runs front-to-back, the Y-axis runs left-to-right, and the Z-axis runs bottom-to-top. This ensures all teams and officials measure things the same way.

  • Right-handed Cartesian coordinate system with three axes (X, Y, Z)
  • X-axis is longitudinal (front-to-back), increasing toward the rear
  • Y-axis is transverse (left-to-right), increasing toward the right side
  • Z-axis is vertical, increasing upward from the car's base
Official FIA Text

The Car Coordinate System is a right-handed Cartesian [X, Y, Z] coordinate system. The X axis is the longitudinal direction of the car and increases rearwards. The Y axis is the transverse direction and increases to the right. The Z axis is the vertical direction and increases upwards.
