For efficient and powerful progress, the C 200 CDI and C 220 CDI have undergone numerous technical enhancements and now deliver even more power and significantly more torque. The oil spray nozzles were enlarged to improve piston cooling. And also thanks to an optimised oil supply to the friction bearings, the C 200 CDI now develops 100 kW (136 hp) and the C 220 CDI has an output of 125 kW (170 hp). Added to that, metal glow plugs have been replaced in both engines by ceramic ones which are able to attain higher temperatures for improved cold-running properties. All the diesel engines are also equipped as standard with a particulate filter[1].
