53 Series models

The 53-series models of the CLS, E-Class Coupe and E-Class Cabriolet combine powerful performance with sporting style and high efficiency.

At the heart is the new electrified 3.0 litre in-line engine with twin forced induction delivered by the combination of an exhaust-driven turbocharger and an electric auxiliary compressor. The EQ Boost starter generator temporarily delivers additional power as well as additional torque, and powers the 48-volt onboard electrical system.

The six-cylinder in-line engine offers top performance and intelligent electrification in a single unit. It produces an output of 320kW and develops a peak torque of 520Nm. Its EQ Boost starter generator temporarily delivers an additional output of 16kW as well as 250Nm of torque.

The EQ Boost starter generator combines a starter and an alternator in one powerful electric motor that sits between the engine and the transmission. With its assistance, the electric auxiliary compressor can build up high boost pressure without delay. This means that the torque available for acceleration increases more rapidly, until the exhaust-driven turbocharger kicks in.

The powertrain is coupled with the AMG Speedshift TCT 9G transmission, which impresses with extremely short shift times, fast response to shift paddle commands, double-declutching function and multiple downshifts. Whether automatic or initiated by the driver using the steering wheel shift paddles, upshifts or downshifts are implemented instantly. Especially in the “Sport+” and in manual driving modes, the transmission is very responsive.

le differential, and the nine-stage AMG traction control take longitudinal and lateral dynamics to a new level.

AMG dynamics enhances driving pleasure, too: this built-in dynamic handling control extends the functions of the ESP, allowing
