Power Unit Energy Flow Devices

In Simple Terms

F1 cars can only use two power sources to move: the traditional engine and the ERS-K (kinetic energy recovery system). Teams are not allowed to use any other devices or alternative power systems to propel the car or capture energy. This rule ensures all teams compete with the same basic technology.

• Only the engine and ERS-K are permitted power/energy devices
• No alternative propulsion systems or energy harvesting devices allowed
• Ensures competitive fairness by limiting technological innovation in power sources
• Any unauthorized device violates technical regulations
