With a design perfected through an immaculate sense of style, highly exclusive appointments and cutting-edge technology, the extensively updated Mercedes-Benz CL-Class underscores its claim to supremacy as the summit of automotive refinement. The entirely re-designed 320 kW (435 hp) V8 biturbo engine of the CL 500 BlueEFFICIENCY, with a combined consumption of 9.5 litres premium-grade petrol per 100 km, opens a new dimension of efficiency in the luxury coupé category. Its NEDC figures show savings of up to 23 percent over its predecessor model, CO2 emissions having dropped from 288 grams per kilometre to 224 grams per kilometre. This significant reduction is achieved thanks to the newly-developed BlueDIRECT technology with third-generation spray-guided direct injection, with the contribution of the specially-designed BlueEFFICIENCY package of the CL 500 BlueEFFICIENCY. The package includes, among other things, energy-efficient control of alternator, fuel pump, air-conditioning compressor and power-assisted steering system, as well as the ECO start/stop function. It also features the use of low rolling resistance tyres and the energy-optimised Active Body Control system. In addition, the Mercedes-Benz developers equipped the CL-Class with state-of-the-art multimedia technology, thus helping this model, produced with a high proportion of hand-finished work, to retain its position as the epitome of quality in its class.

With the new generation of the CL-Class, the Stuttgart-based automaker focuses on fuel consumption and exhaust gas emissions in the exclusive high-end segment, too. According to Dr Dieter Zetsche, Chairman of the Board of Management of Daimler AG: “The CL is the ideal ambassador for our brand. It combines in a particular degree those things that characterise Mercedes-Benz: fascination, perfection and responsibility. And with the new generation we have gone a step further, too – especially in the realm of efficiency. But in terms of design, safety, comfort and output, too – the CL shows the way forward: simply follow Mercedes”

In addition, a combination of cutting-edge camera and radar-based assistance systems unique in the luxury coupé segment, including the innovation of the Active Lane Assist and Active Blind Spot Assist systems, makes of the CL-Class
a "thinking" partner of the driver. The modified Active Body Control (ABC) with crosswind stabilisation system and the Direct-Steer system also contribute to enhancing safety and driving enjoyment.

The exterior appearance of the new CL-Class generation is characterised by the terse profile of the bonnet, the dynamic V-shape radiator grille and the curving headlamps – design details that discreetly but effectively emphasise the car's elegant yet powerful lines.

The front bumper, too, presents a new design with three air intake openings and a chrome trim strip. An LED strip with chrome surround for the daytime running lights is elegantly integrated in the side openings for the brake cooling air. With their standard-fit Intelligent Light System (ILS) and Adaptive Highbeam Assist, the headlamps offer state-of-the-art illumination technology. The latest LED technology in the turn indicators and position marker lamps rounds off the car's advanced image. The rear of the vehicle is characterised by the newly-designed tail lamps.

The new-generation CL-Class also assumes a pioneering role in the drive system sector. Under the bonnet of the CL 500 BlueEFFICIENCY and CL 500 4MATIC BlueEFFICIENCY a new V8 biturbo engine with BlueDIRECT technology delivers its impressive power. With its 4663 cc displacement, the eight-cylinder engine produces 320 kW (435 hp) so that despite 0.8 litres less displacement, it is still around 12 percent more powerful than its predecessor, which had an output of 285 kW (388 hp). At the same time, torque was raised from 530 Nm to 700 Nm – an increase of 32 percent. Combined consumption in the New European Driving Cycle (NEDC), on the other hand, drops by 23 percent to 9.5 litres of premium petrol per 100 kilometres for the rear-wheel drive version. CO2 emissions consequently sink from 288 grams per kilometre to 224 grams per kilometre. The CL 500 BlueEFFICIENCY requires a mere 4.9 seconds to accelerate from a standstill to 100 km/h (previous model: 5.4 seconds). Summing up: the CL 500 BlueEFFICIENCY is significantly more agile, torquey and thriftier than its predecessor.

The BlueDIRECT technology package of the V8 biturbo includes a series of new developments, unique in their combination. Worthy of mention among these is the third-generation spray-guided direct petrol injection with piezo injectors and multi-spark ignition with up to four ignition sparks within a millisecond. Together both enable an innovative combustion process called "homogenous split". Other factors contributing to the exemplary low fuel consumption continue to be the consistent use of friction-optimised pistons, piston rings and cylinder barrels, the on-demand control of oil pump and the new three-phase thermal management in the coolant circuit. The luxury coupé's package includes the ECO start/stop function and alternator control in accordance with the handling situation and on-board voltage with kinetic energy recuperation in overrun mode.

The CL 600, with its 380 kW (517 hp) 12-cylinder biturbo engine remains the top-of-the-line model: it accelerates the luxury coupé from a standstill to 100 km/h in breath-taking 4.6 seconds and now also complies with the Euro 5 emissions control standard.

Mercedes-Benz also offers another radar based system for the luxury coupé as a component of the driver assistance package PLUS in the form of the PRE-SAFE® Brake. If the driver is distracted and fails to recognise the imminent danger of a rear-end collision or the warning signal of an assistance system, this system can intervene and brake the vehicle independently. If the driver fails to react even after automatic, partial braking action, this most recent development stage of
the PRE-SAFE® Brake activates the maximum braking pressure around 0.6 seconds before what it now recognises as an unavoidable collision -- an emergency braking action that can significantly mitigate the severity of the impact. The
PRE-SAFE® Brake thus acts as a kind of "electronic crumple zone".

Overtiredness is one of the most common causes of accidents. This is why Mercedes experts have developed the ATTENTION ASSIST system which forms part of the standard equipment of the new generation CL-Class. As the vehicle is being driven, the system continuously evaluates more than 70 different parameters in order to identify driver drowsiness and provide a warning before the dangerous microsleep phase begins. Observing the driver’s steering behaviour has proved to be a particularly strong indicator: several years of practical research by Mercedes-Benz have shown that drowsy drivers make minor steering errors which they often correct very rapidly in a characteristic way. This steering behaviour is recognised by a special steering angle sensor. Observing the driver's eyes cannot always provide conclusive evidence of sleep since many drivers can experience micro-sleep with their eyes open.

The CL-Class also meets the highest standards in terms of driving dynamics and agility. This is in part thanks to Direct-Steer, with a steering ratio that varies with the steering angle, and modified Active Body Control (ABC) with crosswind stabilisation (standard for CL 500 BlueEFFICIENCY and CL 600). This latest stage in active body development modifies the wheel load distribution via the ABC spring struts within milliseconds, depending on crosswind direction and intensity, to the extent that it can largely compensate the effects of the crosswind.

The Active Body Control suspension system with which Mercedes-Benz ushered in new dimensions of driving dynamics in the preceding C 215 model series in 1999, is unique worldwide as it not only regulates roll, but pitching and squatting movements as well, ensuring a perfect harmony of comfort and handling stability. Since the introduction of this innovative system, engineers in Sindelfingen have continuously improved on it, so that eleven years later it still marks the summit of automotive engineering. In addition to crosswind stabilisation, the new suspension features an energy-optimised hydraulic pump that takes part of the burden off the engine, contributing towards reducing fuel consumption.

Additional safety and agility at the physical limits is provided by the standard-fit Torque Vectoring Brake in the new-generation CL-Class – targeted, one-sided braking intervention at the inside rear wheel when cornering. This enables the luxury coupé to turn into the bend under precise control with even greater agility.

In the interior, too, Mercedes-Benz developers and designers perfected the
CL-Class, paying careful attention to detail. A total of four different kinds of fine wood open up the possibilities for perfectly matched material and colour concepts according to your personal taste: apart from light and dark high-gloss burr walnut, there is black ash and high-gloss brown poplar (CL 600). Another particularity: in line with the central importance awarded to the concept of sustainability within the Mercedes-Benz corporate philosophy, the CL-Class employs only European wood from renewable forestry sources. Most of the wood parts are hand-made and matched individually for colour and grain by experienced craftsmen.
The seat covers of the new CL-Class are of the most exquisite quality. For this luxury model there are two different kinds of leather available which thanks
to their low pre-tensioning and consequent wrinkle effect appear supple and comfortable from the very first glance. There is a choice of five tasteful colour combinations for the vehicle interior: black/black, savannah beige/cashmere beige, sahara beige/black, and the novel combinations alpaca grey/basalt grey and aubergine/black.
The multifunction steering wheel of the CL-Class has also been modified by the Mercedes-Benz designers: in future the rim and airbag module are lined with soft nappa leather as standard. The new, flatter airbag module also lends a sporty touch to the multifunction steering wheel covered in leather sewn with sophisticated double stitching.
Apart from this, Mercedes-Benz makes more use of light as a styling element in the vehicle interior. In future customers who specify the optional ambient lighting (standard for CL 600) have a choice between three lighting moods: solar (amber), neutral (white) and polar (ice blue).

The AMG Sports package with AMG bodystyling and AMG light-alloy wheels gives the luxurious two-door car an even more dynamic look. At the front the newly-designed front apron ensures an imposing, muscular appearance. Its distinguishing feature is a tapered air intake with a wider lower edge. The side skirts continue the design of the front bumper, with striking contours that find an echo in the rear apron. The independent rear bumper with a black insert is the perfect finishing touch.

Further highlights include the 19-inch AMG 5-spoke light-alloy wheels painted in sterling silver. With their broad format 255/40 (front) and 275/40 (rear), not only do they fill the wheel houses perfectly, lending the CL-Class an exceptionally dynamic presence, but also enhance its handling characteristics even more. In addition, silver-colour painted brake callipers with Mercedes-Benz lettering on the front axle wheels emphasise its sporty appearance. The CL 500 4MATIC BlueEFFICIENCY with AMG Sports package is fitted with 255/40 R 19 tyres on both front and rear axles. Optionally, 20-inch AMG light-alloy wheels in twin-spoke design with tyre sizes 255/35 and 275/35 are also available.

Wood trim and the wood/leather steering wheel in black ash give the high-quality vehicle interior a very special feel. The AMG Sports package also includes sports pedals in brushed stainless steel with black rubber studs and velour floor mats with AMG lettering.
