By now, of our readers may have gleaned there is a new Mercedes-Benz C200 – from the little badge at the end that says C200 and not the C200 K — the new Mercedes-Benz CGI was slipped into the Malaysian dealer network very – there was no fanfare, no official just an overnight change of in the showroom from the C200 to the C200 CGI. The people at Malaysia probably figured out since the CGI had already been in the E200 series, there was no for any publicity when introducing the with the same engine.

The between the C200K and the C200 CGI is in the only, but it is a very significant The K in the C200K is the German word which in the language we all understand, is a charger. The purpose of the supercharger is to additional air into the engine together with the fuel, to get efficient burning of the fuel (on of the additional oxygen available in the and as a result, more power. is partly the reason why a 1.8 litre such as the one in the C200K can develop 184 at 5,500 rpm and 250 Nm of torque at between to 5,000 rpm. The supercharger is by a belt attached to the main of the engine, and a clutch system in principle like the air-conditioner clutch allows the supercharger Kompressor) to kick in on demand, and when not needed. This provides instantaneous linear to throttle demands, as the engine the supercharger compressor directly, and as the speed builds up, so does the pressure, and pumps in more air in to the fuel being injected the cylinders.

The C200 CGI (which stands for Gasoline Injection’) is basically the base M271 DEH engine, with a turbo-charger. The term Gasoline Injection is to differentiate the CGI which runs of petrol the CDI engine, which denotes Diesel Injection’, or a turbocharged engine, obviously using as its fuel source. A turbocharger is a rotating device that is to the exhaust system of an engine. are two sets of fins on a single exhaust gases coming out the engine are channeled over one set of fins to drive the shaft is attached, and in doing so, it turns the on the other side, which in draw in air from the outside of the into the cylinders. The force of the builds up the air pressure within the cylinders, and thus allows air than is ordinarily possible to the cylinders. Both the supercharger and do the same thing; only the system is different. A turbo however takes time to up – it takes a little time for the fins to build up pressure, so suffer a thing called – however, modern computer has managed to minimize this lag to zero, so today, you will not the kind of lag that we used to in the old days. In addition, the size of chargers has an effect on the amount of lag

that one will experience, and the on the Mercedes C Class is relatively

In the early days of the supercharger and the biggest challenge faced by makers was heat generated by the air, the heat generated by the gases acting on the turbocharger, and efficiency. At that time, it was that superchargers ran relatively and so some engine makers to go the direction of the supercharger. Other makers found that charging could potentially more power, as the faster the spun, the more the potential that could be developed. The major problem faced in the days of turbo charging was efficiency and heat, with the compromising reliability.

Later on, as injection technology improved, as did technology, it was found that precise metering of fuel was and the same technology made it to monitor the air-fuel mixture, and operating temperatures down. engine thus became reliable and fuel efficient.

The used to associate turbocharged with high fuel and poor reliability, in addition to durability – that scenario has – the modern turbocharged cars are as fuel efficient, if not more efficient as conventional engined

What we have in the C200 CGI is one engine – the Mercedes-Benz engine have, through extensive and testing, developed an engine to the Kompressor engine – it delivers the 184 horsepower at a lower engine (5,250 rpm), and 270 Nm (+20 Nm) starting earlier from as low as rpm, all the way to 4,600 rpm. In the CGI engine at each engine rpm delivers more power and official test figures on consumption place the CGI at between 7.2 – 7.9 per 100 kilometres, compared to 7.9 – 8.1 litres per 100 for the C200 Kompressor.

Bearing in of course that the above results were obtained test conditions, my own experience the two cars over the same conditions actually yielded no difference in the amount of fuel Both the C200K and the C200 CGI are of all extremely frugal on fuel, around 9.3 litres per 100 kilometres an identical 300 kilometre driving (The drives were over two different days, and conditions such as humidity, and wind would have different, so it was not an exact apple to comparison. Suffice to know for the man in the street, there is no real

What is different, though, is the to throttle – the turbocharged C200 CGI is responding to throttle easily, and up speed just a wee bit faster, from zero to 100 km/h in 8.2

From the outside, the C200 CGI identical to the C200 Kompressor, for the different badges on the boot lid denote the two models. The C200 CGI is said to be part of the new BlueEFFICIENCY by Mercedes-Benz – the Mercedes engineers harnessed potentials from all of development to reduce weight, drag, rolling resistance, and organize onboard energy more efficiently.

Body has been shaved by 19 to 32 kilograms on the model, and drag coefficient is an excellent 0.26, placing the amongst the best in this of vehicles. Improvements that to this include smooth cladding to reduce turbulence the car, sealing of the joints the bonnet and headlamps, as well as the bumper and headlamps to improve the around the front end. The of attention to detail even the exterior mirrors, which are using a wind tunnel.

All in all, the C200 CGI remains as good to drive as the C200K, if not

Therefore, the C200, renewed the CGI engine, makes a good proposition, considering that it only marginally more, at
