Check your manual for the specific type you have... Several all-new M272 and OM642 V6 engines were introduced later in the year. In North America, the changes took effect for the 2006 model year. The C 230, C 280, C 350 replaced the C 240 and C 320, the new-generation six-cylinder engines developed substantially more power than the older versions, by as much as 24 percent, whilst also increasing fuel economy and reducing CO2 emissions. The C 230, C 280 and C 350 developed 150 kW (204 PS), 170 kW (231 PS) and 200 kW (272 PS) respectively. The three-valve twin spark design was replaced by a four-valve design, now with variable valve timing. On the diesel side, Mercedes-Benz released a brand-new 3.0-litre V6. Fitted to the C 320 CDI, the new diesel cut CO2 emissions and fuel consumption over the old C 270 CDI, and increased outputs to 165 kW (224 PS) and its torque of 510 N·m (380 lb·ft) made it the worlds most powerful diesel at the time. The C 220 CDI received a power increase from 105 to 110 kW (143 to 150 PS). In addition, these engines also received the new seven-speed 7G-Tronic automatic transmission.
