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.
In the four-cylinder Performance Hybrid, the powerful AMG 2.0-litre turbo engine (with electric exhaust-gas turbocharger) with more than 330 kW can be combined with an electric motor developing up to 150 kW. The total power and the total torque enable future AMG models to achieve driving performance that even surpasses comparable, current vehicles with V8 engines without hybrid drive. The high agility, performance and efficiency of the hybrid 4-cylinder drivetrain will initially be launched in the future generation of the Mercedes-AMG C-Class.
