The Most Efficient C-Class Ever!

Homogeneous Direct Injection With Spark Ignition And Turbocharging

Kuala Lumpur, 5 March 2010 – Mercedes-Benz Malaysia is proud to present the latest C 250 CGI BlueEFFICIENCY with new Charged Gasoline Injection (CGI) technology. This pioneering injection system is another trend-setting technology from Mercedes-Benz resulting in a fuel consumption of just 7.2 – 7.9 litres/100km in combined cycle.

The newly developed 4-cylinder in-line petrol engines of the new M271 DEH engine with direct injection and turbocharging will make the Mercedes-Benz C 250 CGI BlueEFFICIENCY even more efficient and exciting to drive. They raise performance and driving enjoyment to a new level, while demonstrating exemplary economy and environmental compatibility.

Furthermore this engine complies with the EU5 emission standard and is especially thrifty on fuel and that in spite of its top performance in terms of torque, output and noise reduction. This is achieved by means of the following measures:

  • homogeneous direct injection and an increase in the compression ratio for a higher rate of efficiency
  • turbo charging for an increase in output combined with a smaller displacement (downsizing)
  • adjustable intake and exhaust camshafts to ensure smooth torque delivery over entire length of engine speed range with low fuel economy and emission

Performance wise, the C 250 CGI BlueEFFICIENCY achieves 150 kW/204 hp and offers 310 Newton metres of torque. The car requires only 7.4 seconds for the sprint from 0 to 100 km/h with the new engine.

BlueEFFICIENCY In The C-Class: Fuel Consumption Reduced By up to 12%

For the new BlueEFFICIENCY models, Mercedes engineers have harnessed potentials from all fields of development to reduce weight, aerodynamic drag and rolling resistance yet further, and to organise the onboard energy management of these saloons even more efficiently.

The specialists in Sindelfingen have made very detailed improvements to the comprehensive lightweight construction concept of the C-Class, and have managed to shave off between 19 and 32 kilograms of weight depending on the model.

With a drag coefficient (Cd figure) of 0.26, the C-Class is among the most aerodynamically efficient notchback saloons in its market segment. This is the result of a whole series of intelligent details, such as the tail lights with ventilation slits: these reduce drag by influencing the airflow along the side walls, causing it to break off at the tail lights without causing turbulences behind the vehicle's rear end. In this way the patented tail lights of the C-Class replace the usual boot lid spoilers.

Mercedes engineers have succeeded in bettering even the highly impressive Cd figure of the C-Class with a number of other detailed measures:

  • Smooth underbody cladding ensures that the air can flow beneath the vehicle body without turbulences.
  • Sealing the joins between the bonnet and headlamps, as well as between the bumper and headlamps, improves the airflow around the front end.
  • The housings of the exterior mirrors were developed in the wind tunnel, and are particularly streamlined in form.

Thanks to this package of aerodynamic measures the Cd figure for the new BlueEFFICIENCY models has been reduced by seven per cent to 0.26, representing another major contribution to fuel economy.

Dynamic Handling Package: comfort and sportiness all in one

Mercedes-Benz has developed a Dynamic Handling Package which offers drivers a choice of two shift programs – Sport and Comfort. Within these two suspension modes, the shock absorbers are subject to variable electronic control.

A total of seven sensors monitor the current driving situation and relay their information to an electronic control unit, which then calculates the optimum shock absorber characteristic. Depending on the current road or operating conditions, the system adjusts the damping forces for each individual wheel – variably, for even more ride comfort and individuality. When driving normally on poor road surfaces, a soft damper setting can be selected to maximise occupant comfort while maintaining excellent handling stability and safety. If the driver decides that more brisk progress is called for however, the shock absorber settings can be manually adapted to meet the wish for more dynamic performance.

The driver is able to predetermine the basic vehicle set-up by pressing either the Comfort or Sport button on the dashboard. In Sport mode, the hydraulic forces of the shock absorbers are increased to achieve yet greater handling stability at high speeds and reduce the inherent under steer at speeds up to 120 km/h, for example. With this package specified in the new Mercedes-Benz C 250 CGI BlueEFFICIENCY, the body sits 15 millimetres lower than the Mercedes-Benz C 200 K, featuring shorter springs and thicker stabiliser bars. The newly developed speed-sensitive steering with variable centring is also included. In the interests of agile handling, the steering ratio has been reduced from 14.5 to 13.5. In Sport mode, the system also adapts the accelerator characteristics for more spontaneous engine response. Even the shift characteristics are modified and the shift times shortened on the automatic transmission.

The Dynamic Handling Package also includes a three-spoke steering wheel with shift paddles on the steering wheel. The steering-wheel shift paddles allow drivers to change gear manually without taking their hands off the steering wheel. It also allows sporty and fast motor-racing-style gear changes as well as a sporty flair as the paddles can be clearly seen by the driver.

Mercedes-Benz has succeeded in combining a substantial increase in output with a significant increase in fuel economy. The new locally assembled Mercedes-Benz C250 CGI BlueEFFICIENCY with Avantgarde appointments is priced at RM287,888.00.
