At 8K miles in my S600, it has averaged 20.8 MPG from both city driving (3K) and HW driving (5K).
But I would be very surprised if anyone else could get that kind of mileage out of an S600.

Don't set the trip as you are coasting down Pike's Peak and then claim a 20 mpg number showing, that's meaningless...

Your mpg numbers are so flabbergastingly high in your umpteen S600 mileage post... Next time you start your car in your garage, reset trip computer and leave it alone for the next 1000 miles, then get back to us.

Driving the 7 miles in Austin daily traffic (to/from work) I typically get 17 MPG.
As anyone with access to a topological survey map can attest, its pretty flat from Austin to Fredericksburg (and back: although not without hills.) For those of interest: the 7 mile trip from central Austin to work goes out over Lake Austin Blvd, over the low water crossing at Red Bud Trail, north on Westlake drive, cut over on Toro Canyon rd, to Westlake drive, and across 360. This road has plenty of up and down and plenty of traffic. If anyone is in the Austin Area wants to see how I do this drive, I am willing.

[QUOTE=RJC;7005235]Not normal as most can't even tell if their engines are running at idle.
So this past few days I've had a chance to try a few things, including a 300+ mile round trip with only 2 people in the car.
I have averaged an indicated 24.x mpg (up and back to our cabin at 4000 ft on some twisty mountain roads on CA HWY 4), which is the best so far, although we'll see what the final number is when I fill up at the pump later this week (probably 10% less). This means I'll have gotten close to 450 miles from the tank. Not too bad. (S550 v4). I really have to wonder where the 26mpg EPA numbers come from though. I was driving at 70 +/- mph with no assistance from distronic. I had the ECO game bars all maxed out, I think it said I was at 99% for ECO.
I think that 2 factors have mad a difference:
1) I inflated the tires to 38F/39R (this is the max recommendation per the values inside the fuel filler door)
2) I only had 2 adults in the car, although I had a trunk packed with stuff on the return trip, having filled a shopping cart at Costco and driving all that stuff home.
One other thing I had a chance to focus on. The buzz at idle. It came and went at various stops as I described earlier in the post. This time, when it came, I dropped the car into neutral and immediately the buzz went away. Putting the car back into Drive, it usually came back, although it seems like it was less 'buzzy' when I did. I think it's load related to the transmission and I'm now wondering if it's simply a byproduct of the 4Matic setup. At idle, in Neutral, the engine was completely smooth, you couldn't tell it was on except by looking at the tachometer needle.
Anyway, I really love this car! Best car I've ever owned and an absolute pleasure to drive.

Just to chime in...
I have a 2014 S550 and I average 19.8 MPG. I really don't monitor city vs highway, but just overall.
I alway keep it in sport mode and sport suspension.

Edit: I have never reset trip computer since buying my 2014 S550, 17.3mpg over 32,500 miles...
But being from Southern California, I tend to get caught in something known as a traffic jam...

Thank yo so much for saying exactly what I was thinking. Anyone that drives an S Class Mercedes (W222) and is concerned about mpg is a confused individual that doesn't need to own one in the first place and obviously is an alum of Duh! University.. Also, the 4matic will get less mpg than the base rwd S Class and a 5th grader will tell you that as well, and he/she isn't old enough to drive or doesn't even drive or own one. If the aforesaid mentioned offends you, well, I'm talking about you.
Everyone is different. Some of the wealthiest people on the planet pinch pennies. You or I may not be that way, but what business is that of yours? Sheesh!

I don't mean to belittle anyone's concerns here, but if you are driving a W222, is fuel economy really an issue? Average lease payments on our luxo sleds is what? Like $1,600 to $1,800.00 a month? For probably under $300.00 a month, we could be leasing a beautiful Honda Accord, which would deliver truly exceptional economy, but we have chosen not to. Personally, I have never checked my MPG, as it just seems to be within reasonable parameters for a big, very luxurious sedan that will blow the doors off of 95% of the vehicles on the road. I'm content to leave it at that.
Merry Christmas to all,

Almost 3 hours of driving with CC set at 70 MPH, averaging 65 MPH after leaving Flagstaff from the center of old Flagstaff.
I submit anyone (ANYONE) with driving discipline can get these kinds of numbers.
If you can't it is not the car holding your numbers back.

In the w222 the 4matic and 2 wheel drive get exactly the same gas mileage. I'll trust the engineers at MB over you or even the more intelligent 5th grader.
