Article C5.18.7
MGU-K Minimum Mass Requirements
Chapter: C5
In Simple Terms
The MGU-K (Motor Generator Unit-Kinetic) is a component that recovers energy under braking. This rule states that if the MGU-K's transmission system is located entirely within the power unit, the total weight of the MGU-K and related parts must be at least 20 kilograms to ensure fair competition and prevent teams from making it dangerously light.
- MGU-K minimum mass requirement is 20.0 kg when transmission is fully integrated in the power unit
- This rule applies specifically to the 'PU Mass group' elements defined in the technical regulations
- The location of the MGU-K mechanical transmission affects which minimum mass requirements apply
- Mass regulations prevent teams from gaining unfair advantages through extreme weight reduction
Official FIA Text
Depending on where the MGU-K Mechanical Transmission is located, the total mass of the MGU-K "PU Mass group" elements as referred to in Appendix C4 must be no less than the values defined below: a. If all of the speed ratio of the MGU-K Mechanical Transmission is located in the RV-PU-ERS the total mass of the MGU-K must be no less than 20.0kg.
