MGU-K Mechanical Fixing

Chapter: C5

In Simple Terms

The MGU-K (Motor Generator Unit-Kinetic) is an electrical component that must be physically bolted down to either the car's main chassis (Survival Cell), the traditional engine (ICE), or both. This ensures the component stays secure and doesn't move around during high-speed racing.

  • MGU-K must have mechanical attachment points to ensure structural security
  • It can be fixed to the Survival Cell, the ICE (Internal Combustion Engine), or both structures
  • This rule prevents component failure and maintains car integrity during extreme forces
  • Proper mechanical fixing is essential for safety and reliability in F1 power units
