Mercedes-Benz makes changes to top-of-the-line 2003 CL-Class Coupe

Stuttgart, Germany – Scheduled to be in Mercedes-Benz showrooms this Fall, the updated 2003 model Mercedes-Benz CL-Class Coupe features a subtly restyled body, a revised interior and improved safety features. As well, the 2003 CL 600 will feature a new 500 horsepower V12 engine.

New styling includes a revised twin headlamp ‘face’ with clear-lens design and a restyled front bumper which gives the car a more powerful presence. The housings of the exterior mirrors have also been modified and now include exit lighting which switches on automatically to illuminate the area next to the vehicle when the doors are opened or when the remote-control central locking system is activated. The tail-lamps have redesigned glass covers.

A newly developed twelve-cylinder biturbo 5.5 litre V12 engine generates 500 hp and develops a maximum torque of 800 Newton-metres from 1800 rpm . The new 5.5 litre unit exceeds the power output of the previous Mercedes twelve-cylinder engine by some 36 percent while its torque figure is 51 percent higher. The 2003 CL 600 accelerates from standstill to 100 km/h in just 4.8 seconds (predecessor: 6.1 seconds). The maximum speed is electronically limited to 250 km/h.

In addition to its biturbo system, the new V12 boasts an impressive array of technological innovations including a special low-temperature circuit with two water-cooled charge-air coolers, three valves per cylinder as well as AC dual ignition with continuous ionic current diagnosis for optimum ignition functionality. Thanks to its state-of-the-art engine technology and the effective emission control system featuring two catalytic converters mounted on the firewall, the new Mercedes twelve-cylinder engine already meets the strict EU 4 emission standard which comes into force in 2005. The fuel consumption of the CL 600 is 14.7 litres per 100 kilometres (NEDC combined).

As well, the 2003 CL 55 AMG high-performance Coupe will be powered by the 5.5 litre supercharged V8 unit developed by Mercedes-AMG. This engine also has an output of 500 hp and accelerates the coupe from 0 to 100 km/h in just 4.8 seconds thanks to its 700 Newtonmetres of torque (from 2750 rpm). A five-speed automatic transmission with racing-style steering-wheel shift controls completes the total sporting experience aboard the new CL 55 AMG.

The 306 hp V8 engine for the CL 500 remains unchanged.

All variants of the CL-Class Coupé are equipped as standard with Active Body Control (ABC). This unique system adjusts the suspension and damping settings to the current driving situation second by second and so reduces body movement – when accelerating, cornering or braking – to a minimum. Furthermore, the engineers in Sindelfingen have developed an additional system for the 2003 model-year CL-Class Coupé which constantly monitors the total weight of the vehicle. This information is taken into account in the calculations performed by the Active Body Control system. As a result, the handling is even more dynamic and is largely unaffected by the vehicle load.

For the 2003 model year, Mercedes-Benz is extending the coupé’s safety equipment with the addition of two front-mounted satellite sensors which permit early detection of the severity of an accident and, as a result, the appropriate degree of inflation of the two-stage passenger airbag. Furthermore, the satellite sensors also allow the seat belt tensioners to be triggered at an even earlier stage, thereby ensuring optimum occupant restraint in an impact.

Another new safety feature is the automatic weight classification of the passenger by means of a special measuring foil in the seat cushion. This ensures that the two-stage passenger airbag is triggered in accordance not only with the severity of the accident, but also with the weight of the passenger, too.

The interior of the CL-Class Coupé has a centre console with redesigned switches, while the size of the colour display (16:9 image format ) for the standard COMAND unit with its integral radio and CD player has been increased to 6.5 inches.
