What is MGU-H in Formula 1

what is mgu-h in formula 1

One of the key components when it comes to energy recovery in a formula one car is the MGU-H. It is very common to hear this unit being mentioned during race weekends. If you are new to this sport, you might ask; what is MGU-H in formula 1?

To be able to understand this, you will need to learn some basic principle of physics.

Maybe you remember it from your school, or maybe you do not.

It is the law of conservation of energy.

The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another.

This means that a system always has the same amount of energy, unless it’s added from the outside.

Formula one cars uses a lot of energy when racing. They also waste part of that energy as heat or during braking.

In this article, you are going to learn what MGU-H is, and the role it plays in the energy recovery system of an F1 car.

What is MGU-H in Formula 1?

MGH-U is a component of a hybrid-electric internal combustion engine.

It is important to note that MGU-H is an abbreviation for the Motor Generator Unit – Heat.

This unit is an evolved component of a turbocharger, where the exhaust gasses (the “heat” part of the name) are used to also generate electricity.

MGU-H also functions as a motor.


In conclusion, the MGU-H is an important element in energy recovery of a formula one car.

F1 cars lose energy through gases emitted through the exhaust system.

One role of the MGU-H is to try and recover that waste energy into electrical energy.

When you think about it, this is a very interesting concept.

However, formula one is looking at doing away with the MGU-H unit.

As the power units or engines move into electric era, maybe this cutting-edge technology might become obsolete.

It will be interesting to see how F1 decides on this important component of energy recovery system

Will MGU-H still be used in 2026 engines?

Time will tell
