The Stuttgart-based brand
CLS models will cost between 56,434 euros and 101,094
Stuttgart - The Mercedes-Benz CLS-Class will kick off model year 2007 with three newly developed engines, even better safety and a more extensive range of standard equipment.
The main advantage of the CGI engine (CGI = Stratified-Charged Gasoline Injection) lies in the stratified operating mode from which it takes its name. In this mode the engine is run with high excess air and thus excellent fuel efficiency. Now, thanks to multiple injection, it is for the first time possible to extend this lean-burn operating mode to higher rpm and load ranges too. During each power stroke, a series of injections takes place, spaced just fractions of a second apart. This has the effect of significantly improving mixture formation, combustion and fuel consumption.
Among the most important components of this innovative direct petrol injection system are the fast-acting piezoelectric injectors. They have nozzles which open outwards to create an annular gap just a few microns wide. This gap shapes the fuel jet and produces a uniform, hollow-cone-shaped spray pattern. The microsecond response times of the piezoelectric injectors provide the basis for delivering multiple injections per power stroke, and thus for lean-burn operation. By allowing flexible and efficient control of the combustion process they play a key part in ensuring the engine's outstanding fuel efficiency.
Effortless performance twinned with excellent fuel economy
The Mercedes direct-injection engine can still operate in a lean-burn stratified mode at speeds in excess of 120 km/h. When driving on main roads and motorways at largely constant speed and with proper anticipation, the CGI engine outperforms the fuel economy of the six-cylinder engine with conventional injection technology by up to 1.5 litres per 100 km, a saving of approximately 15 percent. Low fuel consumption and excellent power delivery are not at odds with each other on the second-generation Mercedes-Benz direct petrol injection model. On the contrary, the engine delivers 15 kW/20 hp more power than the conventional-injection V6 and four percent more torque. Thus the CGI engine combines its excellent fuel economy with a level of effortless driving enjoyment that is unprecedented in the six-cylinder segment. This allows the new CLS 350 CGI to accelerate from zero to 100 km/h in just 6.7 seconds on its way to a top speed of 250 km/h (electronically limited).
Two new eight-cylinder engines and a V6 diesel with higher torque
Outstanding safety technology with PRE-SAFE® as standard
In the future the CLS-Classs range of standard equipment will be enhanced by the internationally award-winning occupant protection system PRE-SAFE®. The system automatically responds by preparing the vehicle and its occupants for an impending collision. It does this by tensioning the seat belts of the driver and front passenger, adjusting the front passenger seat to an optimal crash position, and automatically closing the sunroof and the side windows if the vehicle is in danger of skidding. Such precautionary measures ensure that seat belts and airbags offer the best possible protection in the event of an impact. Just as unique as PRE-SAFE® are the NECK-PRO head restraints which are also fitted as standard. During a rear impact the sensor-controlled head restraints are moved forward to provide protection for the drivers and front passengers heads within milliseconds. This allows the crash-responsive head restraints to reduce the risk of whiplash injuries. Mercedes-Benz is fitting the CLS-Class with flashing brake lights as standard to prevent rear-end collisions. These lights are more effective than conventional brake lights at warning drivers approaching from behind. And due to faster braking reaction times, the braking distance can be reduced by about 5.5 metres at 100 km/h. Beginning in mid-2006, standard equipment for the CLS-Class will include the ADAPTIVE BRAKE system originally developed for the S-Class. Electronic control enables the hydraulic braking system to provide support functions which further improve safety during emergency situations or when driving on wet roads. In addition, ADAPTIVE BRAKE makes starting on hills easier and prevents unintended forward rolling at traffic lights or in stop-and-go traffic. The new CLS models will cost between 56,434 euros and 101,094 euros. The price of the CLS 320 CDI will remain unchanged, despite an increased range of safety features and a higher-torque engine.
