MB C230 makes way for C250 CGI in Malaysia

The W204 Mercedes-Benz C230 with the 2.5 liter V6 engine has been replaced by a new more torquey C250 CGI model here in Malaysia. The new C250 CGI like its larger E250 CGI sibling is powered by a higher output version of the 1.8 liter turbocharged direct injection engine. The new C250 CGI goes for RM287,888 in Malaysia.


The new C250 CGI produces 204 horsepower at a lower 5,500rpm point as compared to the V6 model, and more torque – 310Nm between 2,000rpm to 4,300rpm. However, the 7-speed 7G-Tronic has been replaced by a 5-speed automatic, as these 4-pot turbo engines are only available with the 5-speeder while the 7-speeder is mated to the V6 and etc engines. Fuel consumption is much better at between 7.2 to 7.9 liters per 100km.

One thing to note though – these inline-4 CGI engines in Malaysia are a little different compared to the models you get overseas. The inline-4 engine – referred to as the M271 DEH or M271 Evolution – originally had a ‘lean burn mode’ for its direct injection system.


This is a special economy mode where the air-fuel mixture is able to be tuned for more air and less fuel, thus saving fuel and producing good amounts of power at the same time. In lean burn mode, the Piezo injectors inject fuel multiple times in one cycle.

Mercedes-Benz says that our fuel quality is not suitable for lean burn mode thus the lean burn function of the ECU has been deactivated. Our M271 engines will do direct injection but only in homogeneous mode, which uses a ratio of 14.7:1. Being a turbocharged engine, there will probably be thoughts of flashing the ECU with a performance version of the software to gain more power. These aftermarket software MIGHT (I’m not sure) re-enable lean burn and reduce the reliability of your engine. Be sure to check.


For now, the C200K continues to run the supercharged Kompressor version of the M271, but Mercedes-Benz Malaysia says a C200 CGI is coming very soon.
