I have driven the R320 cdi for a year now. On the highway it excels at mpg - 25-26 while loaded down (including a roof cargo box) and going quite fast. I don't remember seeing anything below 20. Around town - in the C mode I get 21-22. I have trouble seeing out of it while backing, but it's quite the "touring" car.

6 week old CDI is getting about 23 with a KD box.
 
I expect that to go up after a year. I am not light on the pedal either.

I have had my 06 for two weeks now, and I'm kind of freaking. I don't drive that much (thank God), but I went from a Chrysler Pacifica (don't laugh, I loved the Pacifica...never a problem) so I was used to that. I never figured out what I was getting in the Pacifica, but it must have been damned good, because I'm a little peeved with the R350 Tank. I thought, because it was very much like the Pacifica (minus the 4-wd), it would be very similar in gas mileage. Gulp (no pun intended). I was a little taken aback. I have had to fill up twice since getting it. As I said, it's only been two weeks. I filled the Pacifica up twice a month, if I drove a lot. So, it's a huge diff. I am bummed out.

I'm serious...around town drive in C mode. Only drive in S mode on the highway or when you know you'll be rocking steady at 55 or above for awhile. You'll see a marked improvement in gas mileage. Try this on a new tank of gas.... and reset all of your counters. You'll see. Don't believe all you read. I know my R320 gets better mileage than a gas model (which is why I bought it) but you can improve your numbers.

Just bought a 08 with 17k miles that is pretty loaded and drove it four hours home. I got 25mpg on the way back. Pretty stunning for a car this big.

I drove my 320 from MD to FL with a loaded cargo box on top, and filled to the brim inside - going 75-80 and got 25+ mpg. It's a marvel. Around town, stop and go can be down to 20, but average 22.5+ in day-to-day driving.

Mpg report of R350 after first tank by johnwang378

Bought a 07 R350 4Matic on labor day weekend. I got 24 mpg on highway. For first tank of gas, I got 20 mpg on the mix of highway and local. I was surprised to see such high number for a car this big.

Mpg after 1st year by ctdan

I've had my 08 R350 for about 14 months mostly driven around town by wife but I was getting approx 17 in town and 22-24 on hwy on the stock tires (Continental Contact). I had to replace those crummy treads after only 15k and a few months ago put on a set of Toyo All Country. Now smoother ride and bump in mpg of about 2 mpg for both in town and on hwy miles.
