CL-Class (C 216)

The epitome of luxury coupés

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.

Mercedes-Benz CL-Class, exterior, 2010 model year


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.

New V8 bi-turbo engine with innovative technology

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 (391 lb-ft to 516 lb-ft) – 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/62 mph (previous model: 5.4 seconds). Summing up: the CL 500 BlueEFFICIENCY is significantly more agile, torquey and thriftier than its predecessor.

CL 600

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 functionand 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 (62 mph) in breath-taking 4.6 seconds and now also complies with the Euro 5 emissions control standard.

A unique combination of driver-assistance systems

CL 600

The new-generation CL-Class consolidates its position as an automotive masterwork and a technology platform of the Stuttgart-based company with the most advanced assistance and protection systems. These highly perceptive assistants convert the Mercedes model into a “thinking” partner that can see, feel and react instantly if it detects a hazard, acting autonomously to prevent accidents or to mitigate their effects. The trailblazing driver assistance systems in the CL-Class are based on state-of-the-art radar, camera and sensor technology.

Driver assistance systems

Thus, in the new-generation CL-Class Active Lane Keeping Assist celebrates its premiere (at the same time as in the S-Class). If the vehicle threatens to cross a continuous lane marking line, the system actuates an electric motor in the steering wheel, causing it to vibrate briefly – giving the driver a discreet but effective warning hint to countersteer immediately.  The active system springs into action if the Mercedes coupé unintentionally crosses a continuous lane marking line to the right or to the left. In this case, it intervenes by gently braking the wheels of the opposite side of the car, helping the driver to stay in the lane.  In order to do this Active Lane Keeping Assist avails itself of the ESP® Electronic Stability Program.

Active Lane Keeping Assist

Active Lane-Keeping Assist evaluates information provided by a camera mounted on the inside of the windscreen.  It identifies the contrast between the road surface and the lane marking lines. In addition to this, using radar the system scans the side of the roadway for crash barriers and other roadway edge markings.  This Mercedes assistance system also evaluates the driver’s actions and can thus reliably determine whether the car is departing from the lane intentionally or not.  For this reason, there is no warning if the driver accelerates hard just before overtaking or when accessing a motorway, or if he brakes hard or steers into a curve.

Targeted brake actuation:  Active Blind Spot Assist

Active Blind Spot Assist

A further innovation Mercedes-Benz offers for the CL-Class is active Blind Spot Assist, a system that makes use of a multi-stage warning concept.  If it detects that a change of lane would be too dangerous, it warns the driver by displaying a red triangle in the glass of the exterior mirror.  Close-range radar sensors monitor the area immediately to the side and to the rear of the car.  If the driver disregards this warning and, for example, actuates the turn indicator, an audible warning also sounds. If the driver continues to ignore the warnings and comes dangerously close to a vehicle in the neighbouring lane, a novel feature of the system acts: a corrective braking intervention via ESP® on the wheels of the opposite side of the vehicle.  This causes a yaw movement about the car’s vertical axis due to the unequal distribution of the braking forces.  If despite this course correction an accident cannot be avoided, the active Blind Spot Assist system can reduce the consequences of a collision through the brake actuation.
