I have a E-320 2009 BluTec; I love the car and I am looking for a new one for my wife. I tried the 2014 E-250 BluTec but was not sure of the performance (handleing and pick up). Has anyone got any thoughts on buying a 2013 vs 2014. I will keep the car for a long time if its a good one.

 

I have a 2011 E350 Bluetec with the V6 diesel. while not an engineer, I also am concerned that the smaller 4 cylinder engines may work harder with higher fuel and turbo pressures. that said, the fuel economy on the smaller engines is impressive.
