Mercedes-AMG is expanding its product range with the addition of three new models and at exactly the same time introducing a new model designation: the 53-series versions of the CLS, E-Class Coupe and E-Class Cabriolet. These models combine powerful performance with sporty style and high efficiency. At their heart lies a new, electrified 3.0-liter engine featuring an exhaust gas turbocharger and an electric auxiliary compressor. The 6-cylinder in-line engine generates 429 hp and delivers maximum torque of 384 lb-ft. Its EQ Boost starter- alternator momentarily offers an extra 21 hp of output plus 184 lb-ft of torque and furthermore packs the 48 V on-board electrical system. Other technical highlights include the AMG SPEEDSHIFT TCT 9G transmission as well as the completely variable all-wheel drive system AMG Performance 4MATIC+.

Distinguishing features which are common to the three new 53-series models include the twin-blade radiator grille, the front bumper in A-wing layout, the AMG-specific side sill panels, the rear bumper with diffuser insert in addition to the round exhaust tailpipe trim components in high-gloss chrome.

“With the new 53-series models we’re extending our portfolio in a first step towards a hybridized future with a leading-edge combination of sporty design, performance and efficiency. The foundation for this is a modern drive configuration in the form of a six-cylinder in-line engine with electrical auxiliary compressor, EQ Boost starter-alternator and 48 V on-board electrical system.
The very spontaneous response to accelerator pedal input, the precision and the layout focusing on driving dynamics are hallmark features of AMG.

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

The six-cylinder in-line engine is distinguished by top-of-the-range functionality and intelligent electrification. The EQ Boost starter-alternator combines a starter motor and alternator in a powerful electric motor and can be fitted between the engine and transmission. This innovation as well as the smart charging via an electric auxiliary compressor and an exhaust gas turbocharger all have the same goal: to enhance the trademark AMG performance and driving dynamics, while at the same time reducing fuel consumption and emissions. And this movement was a successful one: the AMG CLS 53 accelerates from zero to 60 mph in just 4.4 seconds (est.).

High Definition without lag

Supported by the EQ Boost starter-alternator when moving off, the electric auxiliary compressor builds a high charge pressure with no delay, for a quicker increase in torque for acceleration until the large exhaust gas turbocharger is deployed. Because of this the 3.0-liter engine reacts extremely spontaneously and provides a highly dynamic response without turbo lag. An additional bonus is the high degree of refinement of this six-cylinder in-line engine.

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

The conventional 12 V network is similarly supplied in the new network — with a DC/DC converter. Thanks to the 48 V battery, the overall battery capacity in the vehicle is increased, allowing more electric 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 additional hybridization. Another advantage: the same power requires just a quarter of the present of a conventional system. The end result is that the wiring could be thinner and therefore lighter, which leads to saving fuel. The existing 12 V system supplies power to customers such as lighting, cockpit, infotainment displays and control components.

Hybrid operates 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 permits fuel savings which were previously reserved for high-voltage hybrid technologies. For the first time, the EQ Boost starter-alternator is also responsible for idle speed control.

The hybrid functions include boost with 21 hp of output and 184 lb-ft of torque, recuperation, shifting of the load stage, gliding mode and the nearly imperceptible restarting of the engine with the start/stop function.

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

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

Visually, the new 53-series models have a distinctive unique look. A distinguishing feature common to the models is that the twin-blade radiator grille in silver chrome, previously reserved for the V8 AMG versions. Instead of the diamond radiator grille with individual pins, the grille in front of the central radiator now features a black lattice pattern.

The front bumper in an A-wing design is equipped with black flics and a front splitter in silver chrome. The outer air intakes have two horizontal fins in silver chrome. AMG-specific side sill panels give the 53-series versions a more dynamic silhouette.

When seen from the rear, it’s not just the redesigned rear bumper that stands out, but also the classic, round twin tailpipe trim elements in high-gloss chrome. Because of this this provides for superior air flow around the wheel arches. The lip spoiler on the trunk lid is painted in the body colour, but is also optionally available in carbon-fiber.

Exterior: additional features of the AMG CLS 53

Front end of the AMG CLS 53 features other side air curtains: the air flows over them in a targeted manner, thereby improving the aerodynamics in the front and diminishing the Cd figure. The outer lines of the radiator grille extend towards the bottom and lend the CLS a powerful appearance. Also making a contribution here would be the sharply cut, narrow headlamps.

The outside mirrors are positioned on the doors, as in the AMG GT models, ensuring a much more dynamic appearance.

The two-section tail lights visually reinforce the feeling of width of the rear and as an additional functional advantage allow for the large trunk opening. The wider track width combines better cornering with a perfect look thanks to the wheels being positioned farther out. As standard the CLS 53 comes with 19-inch aerodynamically optimized light-alloy wheels, and as a substitute 20-inch wheels can be ordered.

Interior with innovative display concept and operating system

On top of this there’s the control and display concept with bright, double high-definition screens with 12.3-inch screen diagonal in every situation. Visually, both screens under one shared glass cover blend into a Widescreen Cockpit and as a central element consequently emphasize the horizontal orientation of the interior design.

By means of instrument cluster, the standard “Widescreen Cockpit” contains a large display with virtual instruments from the direct field of vision of the driver, in addition to a central display above the center console. Because the cockpit is completely digital, the driver can choose the look from the three different display styles “Classic,” “Sporty” and “Progressive” and configure the information and views related to him/her will. Via the AMG menu, it’s possible to display the engine and transmission oil temperature, lateral and longitudinal acceleration, engine output and torque, increase (charge pressure), tire temperatures and pressures in addition to the current vehicle setup.

They permit the driver to control the entire infotainment system without needing to take his/her hands off the steering wheel.

The infotainment system can also be controlled via the touchpad with control in the middle console and by voice control. Voice control was extended to include vehicle functions. The air conditioning and seat heating/ventilation, interior lighting and the discretionary head-up display can also be controlled by voice commands.

New AMG Performance steering wheel as standard

The synthesis of exclusivity and sportiness is also underscored by the sport seats (featuring an integral chair look in the AMG E 53 Coupe and Cabriolet) using AMG-specific seat upholstery layout and AMG badge, red seat straps and trim components in carbon fiber. The inside is rounded off with the new, standard-fit AMG Performance steering wheel in nappa leather with individualization options like wood inserts in piano lacquer or DINAMICA microfiber in the grip area.

When it comes to interior colors and materials, the three new 53-series models boast significantly more choices than the preceding 43-series models. For the appointments, there is a selection of MB-Tex man-made leather/DINAMICA microfiber, nappa leather and designo interiors. In addition to classic black with red or gray contrasting topstitching, for the AMG E 53 Coupe and Cabriolet there are now also combinations in black/saddle brownish, black/white, black/classic red, designo titian red/macchiato beige and designo titanium grey/black.

For the AMG CLS 53, along with the designo appointments there is also a selection of color combinations in macchiato beige/magma grey, black/Bengal crimson and espresso brown/magma grey, in which case the ambient color can also be repeated on the steering wheel rim. The color concept is systematically continued through the rear area in a wave design. From the AMG CLS 53, the integral seats with adjustable head restraints have also been redesigned and enhanced with respect to their shape, color and material choice. This includes all aspects regarding optimization of comfort, ergonomics, sportiness and safety.

The rear seat row has also been redesigned with three full-size chairs. The chair backrest which folds in a 40:20:40 split as well as height-adjustable head restraints enable greater flexibility and everyday practicality.

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

The new 3.0-liter in-line engine is combined with the AMG SPEEDSHIFT TCT 9G transmission, which impresses with extremely short shift times, fast reaction to shift paddle commands, double-declutching function and multiple downshifts.

Power is transferred to the road by the completely variable AMG Performance 4MATIC+ all-wheel drive, which also comes as standard. This intelligent system combines the benefits of different drive theories: the fully variable torque distribution between front and rear axle not only ensures optimal traction, but the driver is also able to rely on high handling stability and a high level of safety under all conditions, in the dry, in the wet or in snow. The transition from rear-wheel to all-wheel drive and vice versa is seamless, because the smart control is incorporated into the overall vehicle system architecture.

An electro-mechanically controlled clutch connects the eternally driven rear axle variably to the front axle. The best possible torque split is continuously computed according to the driving conditions and driver’s input. It’s thus possible to drive in a continuously variable way from traction- oriented all-wheel drive to only rear-wheel drive. Cross-fading takes place continuously based on a complex matrix. Alongside traction and lateral dynamics, the all-wheel drive also boosts the longitudinal dynamics for much more effective acceleration.

Attributes at the tap of a finger: AMG DYNAMIC SELECT

With the five DYNAMIC SELECT drive modes “Eco,” “Comfort,” “Sport,” “Sport+” and “Individual,” the motorist can tailor the characteristics of the new 53-series models even more to match personal preferences in the press of a button. The available range extends from comfortable and efficient to very sporty. This modifies key parameters, such as the reaction of the engine, transmission, steering and suspension. The suspension set-ups may also be selected manually, if desired.

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 especially sporty spring/damper set-up and always adjustable damping ADS+ (Adaptive Damping System) combines exceptional driving dynamics with high ride comfort. A more rapid spring rate, such as when cornering and braking, effectively reduces body roll.

The front axle is fitted with special steering knuckles and load-bearing joints; all parts are optimized in terms of rigidity. A more negative camber on the front axle and on the multi-link back axle enhances lateral dynamics. The elastokinematics of both axles are designed to be more rigid in general. These measures improve agility and boost the dynamics.

The damping at each wheel is adjusted to suit the current driving situation and the condition of the road. This is done quickly and precisely, using two different valves to the rebound and compression forces in the dampers. The damping characteristics may also be preselected in three modes, “Comfort,” “Sport” and “Sport+,” letting a significantly more noticeable distinction between exceptional long-distance comfort and sporty driving dynamics.

Thanks to pneumatic all-round self-levelling, the 53-series models maintain a constant ride height regardless of the car load. To increase the ground clearance, such as on steep entrances in underground car parks or on ramps, the amount can be increased at the press of a button. The level is lowered automatically when driving at higher speeds. This improves handling stability thanks to a lower center of gravity.

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

The electromechanical speed-sensitive steering features a variable ratio at the 53-series models. Steering power assistance is offered in a choice of two modes — “Comfort” or “Sport.” The corresponding features are automatically activated based on the chosen DYNAMIC SELECT drive application.

Fade-resistant and reliable: the compound braking system

The large braking system with internally ventilated compound brake discs provides reliable and quick deceleration of the 53-series models.

Wellness on long-distance journeys: ENERGIZING relaxation control

The optional ENERGIZING comfort control is available for all 53 versions. It links various relaxation 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 audio moods. Depending on the disposition or requirement of the driver, it creates a unique wellness set-up to enhance well-being and performance.

Intelligent Drive: tech from the S-Class

The AMG CLS 53 features the hottest driving assistance system generation from the S-Class. The range of driving assistance and security systems is modular in structure. Fitted as standard are Active Braking Assist, ATTENTION ASSIST, plus the occupant protection system PRE-SAFE®. New and also part of the standard specification is PRE-SAFE® Audio (prepares human hearing for the expected accident noise when there is a chance of a collision).

Lively Distance Control DISTRONIC and Active Steering Assist now provide more

Comfortable support for your driver to keep a safe distance and steer. The speed is now adjusted mechanically ahead of bends or junctions. Lively Lane Changing Assist has also been significantly enhanced. This system can brace the front occupants for a side impact by nudging them sideways to decrease the risk of injury.

In addition, the AMG CLS 53 adopts the improved camera and radar systems from the Mercedes-Benz CLS and consequently has an ideal view of the traffic requirements. For the first time it also uses map and navigation data to compute vehicle behavior.

Exclusive Edition 1 for the AMG CLS 53

From the time of market launch, the exclusive Edition 1 will be available for the AMG CLS 53 that boasts exceptional interior treatments. Numerous highlights at a nice copper color help to ensure a particularly high-quality interior atmosphere. The leather upholstery in black nappa also includes copper-colored contrasting topstitching, as do the instrument panel, armrests, center console, door panels and piping on the floor mats.

Trim elements and the center console in carbon fiber with copper stitching and the Performance steering wheel with Edition badge evenly underscore the vehicle’s exceptional position. The luxurious character is furthermore reinforced by the ambient lighting with 64 colours, the Memory and Mirror bundle and the exclusive IWC analogue clock.
