Mercedes-Benz CL 500 (2007)

Compared with the outgoing model, the new Mercedes-Benz top-of-the-range coupé has grown slightly in every dimension. 5065 millimetres long, 1871 millimetres wide and 1418 millimetres high, the body is 75 millimetres longer, 14 millimetres wider and 20 millimetres higher than before, providing even more comfort and space on all four seats. The boot capacity has been increased by 40 litres to 490 litres (VDA measuring method).

Control system: fewer switches for more functions

A newly developed control system, which has already been successfully implemented in the S Class worldwide, refines driver-vehicle interaction even further. Above all, it provides convenient, rapid access to frequently used functions such as car radio, DVD player, car phone or navigation system. Depending on the driver's own preference, these systems can be controlled using switches in the centre console, pressing a button on the multifunction steering wheel or using the COMAND controller on the centre console. This central control unit is linked to the large, pivoting COMAND colour display next to the instrument cluster, providing access to the user-friendly main and sub-menus that activate the various functions.

The standard-fit automatic climate control with four independently adjustable temperature zones is also integrated into the new control system. The driver and front passenger can select temperature, air distribution and other settings either using the COMAND controller and menu-based control, or by means of an attractively styled switch array beneath the air vents. The COMAND system allows other individual climate settings to be adjusted such as air distribution and the footwell temperature.

The newly developed integral seats in the CL-Class provide maximum individual seating comfort. "Integral" means that all components of the seat-belt system are in-corporated directly into the seat; hence the seats form an important component in the occupant protection system. The standard specification already provides electric adjustment of the fore-aft setting, inclination of the seat and backrest, seat height, head restraint and length of the front seat cushions. Pneumatic lumbar supports allow the driver and front passenger to adjust the backrest contour to suit their build and consequently reduce the strain on the back muscles.

Optional extras include luxury seats with active ventilation (standard in the CL 600) that provide even more individual comfort, along with the further enhanced multi-contour seats with nine air cushions, and dynamic multicontour seats with massage function (standard in the CL 600).

The driver and front passenger seats with multicontour function have been awarded the AGR ("healthy back campaign") seal of approval.

Active Body Control: the perfect combination of dynamism and comfort

The standard specification in the new Mercedes Coupé features technological innovations that no other manufacturer can match anywhere in the world. First and foremost is the Active Body Control (ABC) suspension system, which in its latest, even more sophisticated guise delivers unprecedented handling dynamics while offering an equally appreciable improvement in ride comfort. Based on sensor signals and using specially designed hydraulic cylinders at the axles, ABC all but entirely eliminates the customary pitch and roll of the body that occur when moving off, cornering and braking. ABC responds with split-second speed to ensure the body damping is adjusted instantly to any situation. At speeds above 60 km/h, ABC lowers the body by up to ten millimetres to reduce drag and improve handling stability.

Intelligent Light System: five lighting functions to match driving and weather conditions

The Intelligent Light System, which makes driving even safer in the dark, is equally unique. Together with bi-xenon headlamps it forms part of the standard specification for the new CL-Class and provides five different lighting functions that are activated to match driving and weather conditions: the new country road mode illuminates the driver's-side edge of the road more widely and brightly than the existing low-beam headlamps. Motorway mode, which comes on automatically when driving above 90 km/h, delivers a uniform cone of light that illuminates the entire road width. In the centre of this cone the driver is able to see around 50 metres further. The enhanced fog lamps are also new, which Mercedes-Benz uses to provide better orientation in adverse weather conditions. Active light function and cornering light function are also part of the standard-fit Intelligent Light System on the CL Class.

PRE-SAFE®: automatic partial braking before an impending accident

Mercedes-Benz is the world's first car brand to develop an anticipatory occupant protection system that recognises a potential accident situation in its early stages and takes anticipatory occupant protection measures: PRE-SAFE® is standard-fit on the new CL-Class. During emergency braking or when skidding is imminent, the system moves the passenger seat into the most favourable position so that seat belts and airbags have maximum effect on impact. It also inflates air cushions in the dynamic multicontour seats (standard in the CL 600), which envelop and support the driver and front passenger. PRE-SAFE® also closes the side windows and the sunroof in critical situations where high lateral dynamics are generated.

Mercedes-Benz has just made this multi-award-winning anticipatory protection system even better in the CL-Class with the newly developed PRE-SAFE® brakes. They operate in tandem with Brake Assist PLUS (BAS PLUS), which warns the driver of an imminent rear-end collision with visual and audible signals and automatically calculates the required braking pressure to prevent an accident. This braking-power support is available as soon as the brake pedal is operated. If the driver does not react to the BAS PLUS warnings, the PRE-SAFE® brakes trigger automatic partial braking where an accident is imminent and slow the CL Class down using around 40 percent of the total braking power.

The automatic partial braking provides the driver with another clear warning to act. If the driver then immediately applies the brakes, the maximum braking force is available and the accident can - depending on the situation - be averted at the last moment. If an accident is unavoidable, the PRE-SAFE® brakes reduce the impact severity and, in turn, the risk of injury to the vehicle occupants.

As with Brake Assist PLUS, the new PRE-SAFE® brakes also utilise state-of-the-art radar technology to scan the situation in front of the car and detect a potential accident. Two short-range radar sensors with a range of 30 metres and a scanning angle of 80° are located behind the front bumper fascia on the CL-Class. The additional long-range radar in the radiator grille has a range of 150 metres.

Mercedes-Benz also offers BAS PLUS and PRE-SAFE® brakes in conjunction with the optional DISTRONIC PLUS proximity cruise control.

Assistance systems: radar sensors make parking child's play

The newly developed parking guidance system (optional extra) also works on the basis of radar technology: the sensors measure the length of a parking space when driving past and show on the cockpit display whether there is sufficient space to park. Once reverse gear is engaged, the display then includes a symbolic representation of the parking manoeuvre; guide lines show the required steering angle and indicate the path into the parking space.

Night view assist with infrared headlamps, reversing camera, voice control for car radio, DVD changer and navigation as well as tyre pressure monitoring system are other optional Mercedes assistance systems for increased handling safety and comfort.

Engines: eight and twelve-cylinder powerplants with noticeably more power

The new luxury Coupé is ready for any challenge on motorways and rural roads thanks to Mercedes' most powerful engines to date. The eight-cylinder powerplant in the CL 500 delivers 285 kW/388 hp and generates a maximum torque of 530 Newton metres from 2800 rpm. As such the newly developed engine outperforms the existing V8 unit by 26 percent in terms of output and 15 percent when it comes to torque. Equipped with four-valve technology, variably adjustable shifting camshafts, a two-stage intake module and tumble flaps in the intake ducts, the new V8 is among the most advanced, powerful engines in its displacement class. The CL 500 accelerates from zero to 100 km/h in just 5.4 seconds (previous model: 6.3 seconds).

An ultra-modern biturbo twelve-cylinder engine under the bonnet of the new CL 600 generates its impressive power. Mercedes engineers have enhanced numerous de-tails of the power unit and, compared to the predecessor model, have increased out-put by 12 kW/17 hp to 380 kW/517 hp. The maximum torque, already on tap from 1900 rpm, has been improved further by 30 Newton metres to 830 Newton metres and remains constant up to 3500 rpm. The new CL 600 accelerates from 0 to 100 km/h in just 4.6 seconds (previous model: 4.8 seconds). And despite the significant per-formance boost the V12 engine consumes 0.4 litres less fuel than the previous CL 600 per 100 kilometres.

Mercedes-Benz has combined the standard-fit automatic transmission with the new DIRECT SELECT gearshift: the driver can select the transmission settings "P", "N", "R" and "D" by nudging a lever on the steering column. Operating commands are transmitted electronically by wire.

Tradition: seven generations of the Mercedes-Benz Coupé

The new CL-Class ushers in the seventh generation of the large Mercedes Coupés. The two-door model replaces the world-beating outgoing model, which joins the ranks of the best-selling luxury coupés with around 46,800 units sold. The history of the large Mercedes Coupés stretches back to 1952 when Mercedes Benz launched the legendary 300 S Coupé - a "car for the world's elite" was the verdict of the motoring press in its day. In 1956 it was followed by the 220 S Coupé as part of the W 180 model series, which fired the public's imagination with its unitised "Pon-toon" body in particular. And in 1961 the220 SEb Coupé (W 111 model series) took up the baton with its stylish elongated body.

In 1981 the SEC Coupés from the C 126 model series were based on the then S Class and remained in the Mercedes-Benz line-up for 10 years with over 74,000 units produced. In 1992 the Geneva Motor Show was host to the launch of the successor model (C 140 model series), powered for the first time by a 290 kW/394 hp twelve-cylinder engine. The predecessor to the new CL-Class Coupé celebrated its world premiere in March 1999, setting new standards with leading edge Mercedes innovations such as the Active Body Control (ABC) suspension system and bi-xenon headlamps.

Mercedes-Benz has built over 178,000 luxury coupés since 1952.
