Power Unit centre of gravity

Chapter: C5

In Simple Terms

The power unit (engine and related components) in an F1 car must have its center of gravity positioned above a certain height threshold (Z=200mm from the reference plane). This rule ensures fair weight distribution and prevents teams from gaining an unfair advantage by positioning heavy components too low in the car.

  • The power unit's center of gravity must be at least 200mm above the technical reference plane (Z=200)
  • This measurement applies to the combined mass of the engine, MGU-K, MGU-H, and related power unit components
  • The rule standardizes power unit packaging to maintain competitive balance across all teams
  • Violations are checked during technical inspections and homologation of power units
