The new innovation benefits from knowledge and technology developed with the Energy Recovery System in the Mercedes Formula One Power Unit and in particular, the Motor Generator Unit - Heat (MGU-H).
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.
