E320 & GL450
Hey Houston. You are comparing diesel with regular unleaded. Around here, diesel is within .05 to .10 of Premium unleaded, which you must use in 450 / 550's.
We haven't hit the magical 25 mpg yet but have not had it out on flat highway, only hill country. She is getting 22+ in combined City/Hwy. Every time I drive it, I am amazed at it's power and accelleration. It pulls the hills and curves on the way home on cruise control and never has to gear down. It's all about the torque.

I agree, but I have to admit, at 45% of the displacement and 147% beter mileage, that 3.0 L is bad azz. One of these days we're going to drag race. I think the Duramax will take her, but I'm not sure. Getting her to run it that hard is the real challenge. If I really want to see, we should swap rides.

2008 GL 320CDI and 2008 ML320CDI
I average 22-23miles/gallon, mostly highway, but I drive fast. The rpm is usually around 2500 while highway driving. I did get 25miles/gallon, once. For a car that big with decent pickup, the gas mileage is incredible. A long time ago, I remember my 1988 landcruiser getting 10miles/gallon, so anything above 10 makes me happy.

I agree with most of the others that the 320 certainly is not underpowered. I chose it over the 450 mostly for its economy and because I think the diesel engine is kind of cool. Diesels (I mean for private use) are pretty rare here in America.
