Stuttgart, Germany: Mercedes-Benz is planning some engine changes to diesel versions of the C-class in a bid to boost its overall fuel consumption rating. Although not yet official, here's a run down of what we can expect to see unveild at the Frankfurt motor show in September.
The C200 CDI will switch from the OM646 four-cylinder common rail diesel engine to the newer OM651 DE22LA red. Capacity remains at 2.2 litres, power remains at 136bhp, but torque goes down by 10Nm to 330Nm.
The C220 CDI will switch from the OM646 four-cylinder common rail diesel engine to the newer OM651 DE22 LA. Capacity remains at 2.2 litres, power and torque remain the same at 170bhp and 400Nm respectively.
A C250 CDI will join the line-up powered by the most powerful version of the OM651 DE22 LA engine. Capacity is 2.2-litres, power peaks at 204bhp, torque is a claimed 500Nm.
The C320 CDI will be renamed C350 CDI and get a slightly more powerful version of Mercedes-Benz's OM642 DE 30LA engine.
Mercedes-Benz insiders have suggested the C250 CDI, which is claimed to return over 47mpg on the Eurpean fuel consumption cycle, could head to North America as part of a plan to reintroduce four-cylinder models to its US line-up.
