Mercedes-AMG defines the future of Driving Performance - Electric Exhaust-gas Turbocharger

Parallel to the development of the eight-cylinder performance hybrids, the next technological stage is taking place: AMG Performance Hybrid in combination with the AMG four-cylinder turbo engine.

The 2.0-litre engine with the internal designation M 139 has so far been used in the compact performance models installed transversely.

As an E PERFORMANCE variant, it will also provide a fitting drive in other future Mercedes-AMG model series.

However, it will be installed longitudinally, thoroughly reworked and its performance significantly increased once again.

The engineers are aiming for the further developed M 139 to once again surpass the world's highest litre output of all four-cylinder series engines.

The biggest innovation is the electric exhaust-gas turbocharger, which is being realised for the first time in a production vehicle.

This technology comes directly from Formula 1 and is called MGU-H (Motor Generator Unit Heat).

The identical system already powers the Mercedes-AMG Project ONE hypercar.
