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 mph, ABC lowers the body by up to 10 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 mode illuminates the left-hand edge of the road more widely and brightly than the existing low-beam headlamps.
Motorway mode, which comes on automatically when driving above 56 mph, 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-equipment 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 seatbelts 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 per cent 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.
