Mercedes bringing MGU-H to road cars

Mercedes are set to make the less than popular MGU-H element of an F1 engine become road relevant in their cars.

The discussion of removing the MGU-H element from F1 engines is one that has cropped up time and time again between the sport’s power unit manufacturers.

The complexity and cost it has added to engine manufacturing means the MGU-H has come under a lot of criticism, but Mercedes, winner of every title during the turbo hybrid era, has consistently championed the element.

They are now at a stage of development where they are ready to introduce the MGU-H element to their road cars, although it will be introduced in a different fashion compared to how it works within an F1 engine.

A new electric exhaust gas turbocharger, which runs at 17,000 RPM, will drive the compressor wheel before exhaust gas flow is accepted.

“We have clearly defined our goals for an electrified future,” the new chairman of the board at Mercedes-AMG, Tobias Moers, said.

“In order to reach them, we are relying on discrete and highly innovative components as well as assemblies.

“With this move we are strategically supplementing our modular technology and tailoring it to our performance requirements.

“In a first step this includes the electrified turbocharger – an example of the transfer of Formula 1 technology to the road, something with which we will take turbocharged combustion engines to a previously unattainable level of agility.”

The transferring of the MGU-H technology and Mercedes’ understanding of it will help improve throttle input response times as well as decrease turbo lag in their road cars.

They will also be able to reach higher torque levels at lower engine speeds.
