The new Mercedes-AMG 53-series models of the CLS, E-Class Coupe and E-Class Cabriolet

Mercedes-AMG is simultaneously extending its product range with three new models and introducing a new model designation: the 53-series models of the CLS, E-Class Coupe, and E-Class Cabriolet. Each combines powerful performance with sporty style and high efficiency, and features a new, electrified 3.0-litre engine that offers twin-turbocharging by way of an exhaust gas turbocharger and an electric auxiliary compressor. The six‑cylinder in-line engine generates 320 kW (429 hp) and delivers maximum torque of 384 lb-ft. Its EQ Boost starter-alternator briefly provides an additional 21 hp of output plus 184 lb-ft of torque and also feeds the 48 V on-board electrical system. Other technical highlights include the AMG SPEEDSHIFT TCT 9G transmission and the fully variable AMG Performance 4MATIC+ all-wheel drive system.

The three new 53-series models share common distinguishing features, including the twin-blade radiator grille, the A-wing design of the front apron, AMG-specific side sill panels, a rear apron with diffuser insert plus the round, high-gloss chrome exhaust tailpipe trim elements.

"With the new 53-series models we are extending our portfolio in a first step towards a hybridized future with a leading-edge combination of sporty design, performance and efficiency. The basis for this is a contemporary drive configuration in the form of a six-cylinder in-line engine with electric auxiliary compressor, EQ Boost starter-alternator and 48 V on-board electrical system. The spontaneous response to accelerator pedal input, precision, and driving dynamics-focussed design are hallmark features of AMG. As such, we are providing a lifestyle-oriented customer group with an additional compelling offering from Affalterbach," explains Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH.

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

The six-cylinder in-line engine is characterized by top-of-the-range performance and intelligent electrification. The EQ Boost starter-alternator, which combines a starter motor and alternator in one powerful electric motor, is fitted between the engine and the transmission. This innovation, intelligent charging via an electric auxiliary compressor, and an exhaust gas turbocharger all have the same goal: to enhance hallmark AMG performance and driving dynamics, while at the same time reducing fuel consumption and emissions. And this move has been successful: the CLS 53 4MATIC+ accelerates from zero to 100 km/h in just 4.5 seconds.

High torque without lag

When starting from a stationary position, the electric auxiliary compressor immediately builds up a high charge pressure, supported by the EQ Boost starter-alternator. This delivers a faster increase in torque for acceleration until the large exhaust gas turbocharger is deployed. As a result, the 3.0-litre engine reacts swiftly and provides an energetic, turbo lag-free response. The high level of refinement of the six-cylinder in-line engine offers an additional bonus.

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

The EQ Boost starter-alternator generates the power for the 48 V on-board electrical system. The conventional 12 V network is likewise supplied from the new network, and uses a DC/DC converter. 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 hybridization. An additional advantage: the same power requires only a quarter of the current of a conventional system. As a result, the wiring can be thinner and lighter, which indirectly contributes to saving fuel. The existing 12 V system supplies power to the lights, cockpit, infotainment displays and control units, among other features.

Hybrid functions thanks to EQ Boost starter-alternator

A key component of the 48 V system, the EQ Boost starter-alternator 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 responsible for idle speed control, as well.

The hybrid functions include a boost with 21 hp of output and 184 lb-ft of torque, recuperation, shifting of the load point, gliding mode and the virtually imperceptible restarting of the engine by 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 a particularly efficient exhaust gas after-treatment system that is mounted near the engine. 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

The new 53-series models have a unique look that includes distinctive common features such as the twin-blade, silver chrome radiator grille that was previously reserved for the V8 Performance models. Instead of the individual pins of the diamond radiator grille, the grille in front of the central radiator now features a black lattice pattern.

The A-wing design of the front apron features 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 lend the 53-series models a more lively silhouette.

When viewed from the rear, it is not just the redesigned rear apron that stands out, but also the classic, round, high-gloss chrome twin tailpipe trim elements. The design of the sides of the mud flaps improves the aerodynamics at the rear, allowing for better air flow around the wheel arches. The paint on the trunk lid's spoiler lip matches the body colour, but can also be optionally ordered in carbon-fibre.

Exterior: Additional features of the CLS 53 4MATIC+

The front apron of the CLS 53 4MATIC+ features additional side air curtains that offer improved aerodynamics at the front and reduce the Cd figure, thanks to targeted air flow patterns. 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, as do the sharply cut, narrow headlamps.
As with the AMG GT models, the exterior mirrors are positioned on the doors, which ensures an even more dynamic look.

The two-section taillights reinforce the sense of width at the rear and allow for a large trunk opening. The broader track width combines better cornering with a perfect look, thanks to the wheels being positioned further out. As standard, the CLS 53 comes with 19-inch aerodynamically optimized light-alloy wheels; optional 20-inch wheels can be ordered.

Interior: An innovative display concept and operating system

The interior of the new Mercedes-AMG models welcomes passengers with model-specific, exclusive appointments, luxurious materials and significantly broadened options, in addition to an innovative control and display concept whose bright, high-resolution displays are optionally available as 12.3-inch diagonal screens. The two displays under one shared glass cover blend into a Widescreen Cockpit and, as a central element, consequently emphasize the horizontal orientation of the interior design.

The optional Widescreen Cockpit contains a large display with virtual instruments located directly in the driver's field of vision, as well as a central display above the centre console. Because the cockpit is fully digital, the driver can choose the look from among three different display styles – "Classic", "Sporty" and "Progressive" – and also configure the information and views according to his/her requirements. The AMG menu shows the engine and transmission oil temperature, lateral and longitudinal acceleration, engine output and torque, boost (charge pressure), and tire temperatures and pressures, as well as the current vehicle set-up.

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.

The infotainment system can also be operated via the centre console's touchpad with controller and by LINGUATRONIC voice control, which has been extended to include vehicle functions. Now, the air conditioning and seat heating/ventilation, interior lights and the optional 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 sport seats that have an AMG-specific seat upholstery layout and AMG badge, optional red seat belts, and trim elements in metal weave or matte silver glass fibre. The interior is rounded off with the new, standard-fit AMG Performance steering wheel in Nappa Leather, which has individualization options such as wood inserts in piano lacquer or DINAMICA microfibre in the grip area.

When it comes to interior colours and materials, the three new 53-series models boast significantly more options than the preceding 43-series models. For the appointments, there is a choice of Nappa Leather and designo interiors. In addition to classic black with red or grey contrasting topstitching, for the E 53 4MATIC+ Coupe and Cabriolet there are now also combinations in black/saddle brown, black/white, black/classic red, designo titian red/macchiato beige and designo titanium grey/black.

For the CLS 53 4MATIC+, alongside the designo appointments there is also a choice of colour combinations in macchiato beige/magma grey, black/Bengal red and espresso brown/magma grey, in which case the ambient colour is also repeated on the steering wheel rim. The colour concept is systematically continued through to the rear area in a wave design. In the CLS 53 4MATIC+, the front seats have adjustable head restraints and have also been redesigned and enhanced in terms of their shape, colour and material. This includes all aspects relating to optimization of comfort, ergonomics, sportiness and safety.

The rear seat row has also been redesigned with three full-size seats. Greater flexibility and everyday practicality are afforded by the seat backrest, which folds in a 40:20:40 split, and height-adjustable head restraints.

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

The new 3.0-litre in-line engine, combined with the AMG SPEEDSHIFT TCT 9G transmission, delivers impressively short shift times, and fast response to shift paddle commands, double-declutching function and multiple downshifts. Upshifts or downshifts are implemented instantly, whether automatic or initiated by the driver using the steering wheel shift paddles. The transmission is exceptionally responsive, especially in the "Sport+" and in manual driving modes.

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 comes as standard. This intelligent system combines the advantages of different drive concepts: fully variable torque distribution between the front and rear axle not only ensures optimal traction, but also means the driver can rely on high handling stability and a high level of safety under all conditions – whether dry, wet, or snowy. The transition from rear-wheel to all-wheel drive and vice versa is seamless, because the intelligent control is integrated into the overall vehicle system architecture.

An electro-mechanically controlled clutch intermittently connects the permanently driven rear axle to the front axle. The best possible torque split is continuously computed according to the driving conditions and the driver's input. It is possible to drive in an adaptable way – from traction-oriented all-wheel drive to purely rear-wheel drive – as cross-fading takes place continuously based on a complex matrix. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration.

Characteristics at the tap of a finger: AMG DYNAMIC SELECT

At the touch of a button, five DYNAMIC SELECT drive modes – "Eco", "Comfort", "Sport", "Sport+" and "Individual" – allow the driver to tailor the characteristics of the new 53-series models even more to suit his/her personal preferences, from efficient and comfortable to very sporty. Each setting modifies key parameters, such as the response of the engine, transmission, suspension and steering. Separate from DYNAMIC SELECT, the driver also has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel. The suspension set-ups can also be selected if desired.

Independent AMG RIDE CONTROL+ suspension

More agility, neutral cornering performance and greater traction come courtesy of the AMG RIDE CONTROL+ air suspension that was developed in Affalterbach. The multi-chamber air suspension, which has a particularly sporty spring/damper set-up and a continuously adjustable damping ADS+ (Adaptive Damping System), combines outstanding driving dynamics with high ride comfort. Body roll is effectively reduced by a harder spring rate when cornering and braking, for example.

The front axle is fitted with special steering knuckles and load-bearing joints; all components have been optimized in terms of rigidity. A more negative camber on the front axle and on the multi-link rear axle enhances lateral dynamics, and the elastokinematics of both axles have been designed to be more rigid, in general. All of these measures improve agility and boost vehicle dynamics.

At each wheel, the damping is adjusted to suit the existing driving and road conditions. This is done rapidly and precisely, using two separate valves for the rebound and compression forces in the dampers. In three modes – "Comfort", "Sport" and "Sport+" – the damping characteristics can also be preselected, which creates a significantly more distinct pronounced difference between 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 vehicle load. To increase the ground clearance on steep entrances in underground car parks or on ramps, for example, the level can be raised at the press of a button. The level is lowered automatically when driving at higher speeds, which improves handling stability thanks to a lower centre of gravity.

Direct and clear feedback: AMG speed-sensitive steering

The electromechanical speed-sensitive steering features a variable ratio in the 53-series models. It impresses with its precise, authentic feedback. Steering power assistance is available in a choice of two modes – "Comfort" or "Sport". The corresponding characteristics are automatically activated based on the selected DYNAMIC SELECT drive program. In "Sport" mode, more feedback is conveyed about the vehicle status.

Fade-resistant and reliable: The compound braking system

A large braking system with internally ventilated compound brake discs provides reliable and quick deceleration of the 53-series models. The front is fitted with perforated and internally ventilated brake discs (370 x 36 mm) with four-piston fixed callipers and AMG lettering, while the rear features internally ventilated discs (360 x 26 mm) and single-piston floating callipers.

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 employs specific functions of the air conditioning and seats (heating, ventilation, and massage), surface and steering wheel heating, plus lighting and music moods. Depending on the driver's mood or requirement, it generates a special wellness set-up that enhances well-being and performance.

Intelligent Drive: S-Class technology

The CLS 53 4MATIC+ features the latest generation driving assistance systems from the S-Class, and its range of driving assistance and safety systems is modular in structure. Fitted as standard are Active Braking Assist, Lane Keeping Assist, and ATTENTION ASSIST. Other standard features include PRE-SAFE®, the occupant-protection system, and the new PRE-SAFE® Sound, which prepares human hearing for any accident noise when there is a risk of a collision.

The optional Driving Assistance Package consists of Active Distance Assist DISTRONIC, Active Steering Assist, Active Braking Assist with Cross-Traffic Function, Evasive Steering Assist, Active Blind Spot Assist, Active Lane Keeping Assist and PRE‑SAFE® PLUS. Active Distance Control DISTRONIC and Active Steering Assist now provide even more comfortable support for the driver to keep a safe distance and steer. For example, speed is now adjusted automatically ahead of bends or junctions. In addition, the Driving Assistance Plus package includes PRE-SAFE® Impulse Side, which can brace the front occupants for a side impact by nudging them sideways to reduce the risk of injury in the event of a collision.

The CLS 53 4MATIC+ also adopts the enhanced camera and radar systems from the Mercedes-Benz CLS and thus has an ideal view of the traffic conditions. For the first time, it also makes use of map and navigation data to calculate vehicle behaviour.

Exclusive Edition 1 for the CLS 53 4MATIC+

From the time of market launch, the exclusive Edition 1 will be available for the CLS 53 4MATIC+. The Edition 1 features COPPER ART interior design, whose numerous copper-coloured highlights lend the vehicle a particularly luxurious atmosphere. The black Nappa Leather upholstery also features copper-coloured contrasting topstitching, as do the instrument panel, armrests, centre console, door panels, and piping on the floor mats. Its sumptuous character is further reinforced by 64-colour ambient lighting, the Memory and Mirror package and the exclusive IWC analogue clock.

The new 53-series models celebrated their world premiere on January 15, 2018, as part of the North American International Auto Show (NAIAS) in Detroit, Michigan.

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 Coupe and E‑Class Cabriolet.
