07 E550 gas mileage - why so low?
the 5.5L engine puts out very similar performance #s as the M113 5.5L AMG motor, but why is it rated at only 14 city/20 hwy? even a 1999 E55 (almost 8 years ago!) had 17 city / 24 hwy. wouldn't you think gas #s would significantly increase in 8 yrs time??

The method which they calculate MPG on the car was recently changed. So it's tested in different conditons to reflect real world driving. Previously, you'll get "best case" MPG. Now you're getting average to "worst case". 550 engine is more economical compare to previous 55 AMG. You also have 7spd vs. 5spd tranny to save you gas.

20 all around mpg in a 550! I'd be jumping with joy. I get 21 in my 06 E350 and I'm pleased. But my next E will be a diesel. Right now for the first time, I'm seeing diesel costing less than premium.

14mpg...
Dunno about loosening up a "bit" sounds like you need a whole lot a loosening up!
That's really odd. I have a E500 and with an avg speed per tank of gas around 35-40mph, i consistantly get 20mpg....
all of your numbers sound low to me.
