MPG

We just had our second child and we have decided to move from E350 BT to GL (either gas or diesel).

In the E350 BT on the highway, I got around 40-45 mpg (much more than EPA)

What MPG are you folks get on GL 450 or GL350 BT? I sit close to EPA or different?

Thanks in advance.

I own both GL350 and E Bluetec. E class of course getting much better MPG.
I had about 28MPG on my trip from NYC to Orlando FL. Average from the day I got the car (GL) is 18mpg, but it's mostly NYC driving, so I think it's very good result. Good luck.

My 2007 GL450 typically gets a little more than 16 in all around driving and just over 19 on long highway trips.
