New R6 performance engine for CLS, E-Coupé and E-Cabrio

New nomenclature in the full-size segment

With the new models the performance and sports car brand from Affalterbach is also introducing a new model designation: the 53‑series models, which are making their debut in the guise of the CLS, E‑Class Coupé and E‑Class Cabriolet.

The new 53-series models celebrate their world premiere on 15 January 2018 as part of the American International Auto Show in Detroit/USA.


Special exterior design features which are common to the three new 53-series models comprise:

  • the twin-blade radiator grille
  • the front apron in A-wing design
  • the AMG-specific side sill panels
  • the rear apron with diffuser insert plus the round exhaust tailpipe trim elements in high-gloss chrome

Six-cylinder in-line engine with EQ Boost starter-alternator

The six-cylinder in-line engine is characterised by top-of-the-range performance and intelligent electrification. The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and is fitted between the engine and transmission.

This innovation as well as the intelligent charging via an electric auxiliary compressor and an exhaust gas turbocharger all have the same goal: to enhance the hallmark AMG performance and driving dynamics, while at the same time reducing fuel consumption and emissions.

High torque without lag

Supported by the EQ Boost starter-alternator when moving off, the electric auxiliary compressor builds up a high charge pressure without any delay, for a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed. As a result the 3.0-litre engine reacts extremely spontaneously and provides a highly dynamic response without turbo lag. An additional bonus is the high level of refinement of the six-cylinder in-line engine.

Paving the way for hybrid functions: 48 V on-board electrical system

The power for the 48 V on-board electrical system is generated by the EQ Boost starter-alternator. Thanks to the 48 V battery, the overall battery capacity in the vehicle is increased, enabling more electrical energy to be made available ‑ and therefore also allowing innovative functions to be introduced, for example. The 48 V on-board electrical system is therefore paving the way for further hybridisation. An additional advantage: the same power requires only a quarter of the current of a conventional system. The result is that the wiring can be thinner and therefore lighter, which indirectly contributes to saving fuel. The existing 12 V system supplies power to consumers such as lights, cockpit, infotainment displays and control units.

Hybrid functions thanks to EQ Boost starter-alternator

The EQ Boost starter-alternator is a key component of the 48 V system and not only serves as an alternator, but is also responsible for hybrid functions. This allows fuel savings that were previously reserved for high-voltage hybrid technology. For the first time, the EQ Boost starter-alternator is also responsible for idle speed control.

The hybrid functions include boost with 16 kW of output and 250 Nm of torque, recuperation, shifting of the load point, gliding mode and the virtually imperceptible restarting of the engine with the start/stop function.

Because the belt drive for ancillary components on the front edge of the engine is omitted, the installation length of the new six-cylinder engine is also significantly reduced compared with conventional six-cylinder engines. This creates space for an exhaust gas aftertreatment system mounted near the engine, which is therefore particularly efficient. The standard-fit particulate filter is the only part of the exhaust system that is under the floor.


Exterior: twin-blade radiator grille and round twin tailpipe trim elements

Additional features of the CLS 53 4MATIC+

The front apron of the CLS 53 4MATIC+ features additional side air curtains: the air flows over them in a targeted manner, thereby improving the aerodynamics at the front and reducing the Cd figure. The front splitter connects seamlessly with the air curtain and reduces lift at the front axle.

The outer lines of the radiator grille widen towards the bottom and lend the CLS a powerful appearance. Also making a contribution here are the sharply cut, narrow headlamps.

The exterior mirrors are positioned on the doors, as in the AMG GT models, ensuring an even more dynamic look.


Interior with innovative display concept and operating system

There is the innovative control and display concept with bright, high-resolution displays optionally with 12.3-inch screen diagonal in each case. Visually, the two displays under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasise the horizontal orientation of the interior design.

The touch-sensitive Touch Control buttons on the steering wheel respond to swiping movements. They enable the driver to control the entire infotainment system without having to take his/her hands off the steering wheel.

New AMG Performance steering wheel as standard


Short shift times, high efficiency: the AMG SPEEDSHIFT TCT 9G transmission

The new 3.0-litre in-line engine 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.


Fully variable AMG Performance 4MATIC+ all-wheel drive

Power is transferred to the road by the fully variable AMG Performance 4MATIC+ all-wheel drive, which also comes as standard. It is possible to drive in a continuously variable way from traction-oriented all-wheel drive to purely rear-wheel drive.


Characteristics at the tap of a finger: AMG DYNAMIC SELECT

With the five DYNAMIC SELECT drive modes “Eco”, “Comfort”, “Sport”, “Sport+” and “Individual”, the driver can tailor the characteristics of the new 53-series models even more to suit personal preferences at the press of a button.


Independent AMG RIDE CONTROL+ suspension

More agility, neutral cornering performance and greater traction come courtesy of the AMG RIDE CONTROL+ air suspension developed in Affalterbach. The multi-chamber air suspension with particularly sporty spring/damper set-up and continuously adjustable damping ADS+ (Adaptive Damping System) combines outstanding driving dynamics with high ride comfort.

The damping characteristics can also be preselected in three modes, “Comfort”, “Sport” and “Sport+”, allowing a significantly more noticeable differentiation between excellent long-distance comfort and sporty driving dynamics.


Direct and with clear feedback: the AMG speed-sensitive steering

Fade-resistant and reliable: the compound braking system

Perforated and internally ventilated brake discs measuring 370 x 36 mm with 4-piston fixed callipers and AMG lettering are fitted at the front, with internally ventilated discs measuring 360 x 26 mm and single-piston floating callipers at the rear.

Wellness on long-distance journeys: ENERGIZING comfort control

The optional ENERGIZING comfort control is available for all 53 models. It links various comfort systems in the vehicle and uses specific functions of the air conditioning and seats (heating, ventilation, massage), surface heating and steering wheel heating plus lighting and music moods. Depending on the mood or requirement of the driver, it generates a special wellness set-up to enhance well-being and performance.

Intelligent Drive: technology from the S-Class
