Mercedes-AMG has revealed plans to use knowledge and technology from F1 Electronic Recovery System and Motor Generator Unit – Heat in its new road cars.

Mercedes is already in the final development stage at Affalterbach as they are to use knowledge and technology from ERS and mainly MGU-H in its road cars, thereby revealing details of first F1 to automotive transfer of information.

The MGU-H has been a topic of debate for some time now, even to the extent that it was dropped from the new F1 regulations, only to be put back. The manufacturers argued that years of effort put in will result in waste if the tricky component is removed.

Mercedes will deploy an electric exhaust gas turbocharger in its new road cars. It is being developed in partnership with Garrett Motion to resolve the ‘conflict between having a smaller turbocharger that reacts faster but achieves relatively low peak performance, and a larger turbocharger with higher peak performance that suffers from turbo lag’.

The release further explains the ERS and MGU-H addition from F1: “The highlight of the new electric exhaust gas turbocharger is a slim electric motor integrated onto the charger shaft, between the turbine wheel on the exhaust side and the compressor wheel on the fresh air side.

“The electronically-controlled electric motor drives the compressor wheel before it accepts the exhaust gas flow. The electrification of the turbocharger significantly improves immediate response from idle speed and across the entire engine speed range, while also eliminating turbo lag.

“Therefore, the combustion engine responds faster to accelerator pedal input and provides a more dynamic driving feel. It also enables higher torque at low engine speeds, which enhances agility and acceleration from a standstill.”

“We have clearly defined our goals for an electrified future,” said Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH. “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 F1 technology to the road, something with which we will take turbocharged combustion engines to a previously unattainable level of agility.”
