BlueEFFICIENCY label carried on the Mercedes-engined variant bids CGI illustrate the efficiency and environmental friendliness of this Stuttgart-born car. Variant C250 CGI that we try this time, carrying the 4-cylinder inline engine of 1.8 liters, with peak energy bid that can match the engine's 2.5 liter V6 it replaces C230.
Mercedes-Benz C-class Design and Technology
In terms of design and dimensions, C250 CGI does not vary much with the previous C-class. But the C250 CGI designs have been amended in several places to enhance the value of aerodynamics. As a result, C250 CGI has a wind resistance (CoD / coefficient of drag) 0.28 Cd.
Which is completely different from previous versions is the heart pacemaker is pinned. CGI Technology (charged gasoline injection) which uses a turbocharger with variable geometry as a means of induction, making the coded M271 Evo engine is working more efficiently with the equipment to produce a competent performance. The use of variable geometry turbocharger model allows turbine blades to adjust to engine rpm, so the turbocharger can work at low speed and responsiveness of the engine are felt from the beginning. This is very useful to deal with city traffic is congested.
At CGI engines, engine intake channel on carefully designed in order to produce flow and optimum air vortex, so that combustion can more quickly and completely. And now, the fuel is sprayed directly on each cylinder at an angle of 42 degrees with a precision pressure is set between 50-120 bar. As a result, the air-fuel mixture in CGI engine better than ordinary injection machine, at various levels of the spin machine.
Sophisticated engine power output is equal to the power 2.5 liter V6 engine owned by C230, which is 204 hp. In fact, even better because the peak power occurs when the engine turns the 'new' reaches 5500 rpm (204 hp in the C230 power achieved at 6100 rpm). In addition, CGI technology also produces a greater torque at lower rpm, which is 310 Nm at 2000-4000 rpm. This figure was even better than the C250 which bertorsi 245 Nm which appears on the 2900-5500 rpm. Mercedes claims that the use of CGI technology is also able to boost fuel efficiency up to 20%, with emissions that also claimed to be lower.
Mercedes-Benz C-class Interior
In the interior, Mercy maintain cabin similar to the previous model. Cabin sporty look with dark shades combined aluminum accents in some parts. On the dashboard, hidden monitors that will show the appearance of the audio system and phone settings. Plastic material on the dashboard feels soft and high quality typical Mercy. All audio system settings can be done from the Command button on the center console.
Features on the audio quality is also no doubt thanks to the sound structure that is governed by Harman Kardon Logic7, and CD-changer in-dash six-CD that can load your favorite. One thing that is unfortunate is the lack of multimedia features on this car. Unlike the closest rival, BMW 3-Series has been offering 13 GB hard disk to store your favorite music files, DVD players, and digital TV channels.
At the rear, three passengers can sit freely because it has ample legroom (510 mm minimum and 870 mm maximum). In addition, the Mercedes with a smart save two cup holders in the armrest that can be folded in the middle seat.
Mercedes-Benz C-class Performance
C250 CGI BlueEFFICIENCY engine sounds fine when first turned on. Press the accelerator pedal gently, then the car began to move gently as well. Press the pedal to the aggressive and the car weighs 1.5 tonnes will be turned into a vehicle that is also aggressive, with a roar of sound that can generate enough adrenaline.
Turbocharger with variable geometry was very helpful, especially when requiring acceleration. Mercedes-Benz claims this car travel kpj acceleration 0-100 in 7.4 seconds. However, we can only reached 8.4 seconds when tested. Factor track conditions, weather, and fuel could be things that affect that number. Acceleration of the rotation center was quite satisfying thanks to a torque of 310 Nm is available at 2000-4000 rpm.
Power of 204 hp channeled to the rear wheels via a 5-speed automatic transmission that moves with fairly smooth and fast. A bit disappointing really, considering the C230 it replaces the transmission 7-speed 7G-Tronic is famous for its accuracy and smoothness of movement of gear. Not only that transmission 7G-Tronic is also known to be able to save fuel up to 0.6 liters per 100 km.
Mercedes-Benz C-class Driving and Control
Although pengendaraannya feels a bit harsh on bumpy roads, but there are some things that will make the driver feel confident in driving and controlling the car. First, the Agility Control suspension features MacPherson strut front and multi-link at the rear to provide stability when the car through a variety of corners. Agility control will read road conditions and speed to adjust the stiffness of the suspension. This also resulted in increased agility of the car when maneuvering. In addition, the stability also helped thanks to the presence of features electronic stability control (ESP).
Secondly, while driving in a crowded city, C250 CGI gives a sense of comfort thanks to thermatic dual zone temperature control, audio quality, as well as other convenience features, plus a lightweight wheel. Unfortunately, the swivel radius of 5.42 m, the driver will feel bothered if necessary maneuver in tight places. When reaching the highway, the steering become heavy with increasing speed and was communicative in translating an impassable road surface conditions.
And lastly, thanks to a flexible seat arrangement. Drivers with an average body size of Indonesia will get ample visibility. In addition, the A pillar which usually interfere with vision, designed thin enough so as not bothering the driver's visibility.
Mercedes-Benz C-class Buy and Own
A variety of features designed to facilitate users diusungnya, although sometimes need a little adjustment for those who are not familiar with a Mercedes-Benz. However, note the interior is spacious and can accommodate five adult passengers, and do not forget the trunk of 475 liters volume, larger than the BMW 3-Series is only 460 liters and only slightly smaller than the Audi A4 which reached 480 liters.
From the results of our tests, engine 1796 cc diusungnya recommended to drink fuel RON 95 (minimum RON 91), and capable of taking 10.6 MPA for use in urban and 12.1 MPA for use outside the city. With gasoline filled the tank with a capacity of 67 liters, the C250 CGI able to travel up to 810 kilometers without refueling. A great result for the car in its class.
Mercedes-Benz C-class Rating
Technology CGI engine (charged gasoline injection) provides far leap for the Mercedes-Benz C-Class compact executive car class in the Indonesian market. Bids efficiency, better performance and lower emissions is clearly the most important points for consideration consumers. Moreover, Mercedes-Benz brand is still able to guarantee the values of reliability, luxury, and high image. Driving, control, and quality of homemade still deserves thumbs up. C-class assembled in this country, not least with the C-class imported intact from Germany. Apparently, the work home to Mercy only provide more entertainment (multimedia) for owners of C-class.
