Gas Mileage??
Just curious what others are getting on gas mileage ... not that I expected it to be great but I'm getting about 13 in town and i don't drive extreme by any means ....

I posted about this on another thread somewhere. I can honestly tell you that one can get at least 30 mpg under fairly "normal" weather conditions on the highway. I have had 2 fairly long trips on the interstate since I purchased the car back on April 5. On the first one, driving home to Des Moines from Kansas City, I averaged 30.9 mpg. The second trip is much more complicated and it took place last Sunday. It was a trip from Des Moines to Cedar Rapids, IA and back. On the trip out to Cedar Rapids (heading east on I-80 for the most part), I only averaged 26 mpg due to a wicked 25-40 mph headwind (from the east). On the way back, I was averaging an amazing 31.9 mpg with more of a southeast wind (so not a direct tail wind) at about 15-25 mph or so. Btw, I had 2 passengers going out and 3 on the way back home. Then all hell broke loose. As we expected, we ran into a very severe line of thunderstorms (the same system that produced tornadoes further east and south). Suddenly, the wind was straight out of the west at 60 mph at times along with about the heaviest rain one can ever imagine. The visibility was reduced to about 30 feet. I slowed down to about 25 mph. Almost everyone pulled over on the right breakdown lane. A truck in front of me was weaving back and forth due to the wicked wind. The good thing is that this very severe line was only about 5-10 miles wide and moving east. So it did not take too long to get through it. However, the weather conditions for the last 50 mile drive home was still anything but ideal. The wind diminished considerably but it was still rather heavy rain until a few miles east of Des Moines. By the time we got to my driveway the gas mileage was down to about 28 mpg which, under the circumstances, was still very good.
From all my experiments so far in city driving, I have been averaging about 18 mpg. The trick is not to be too aggressive on the gas pedal after a complete stop and to anticipate stops. I do use the ECO mode all the time. I also use the Auto Pilot option a lot in city traffic. Btw, my odometer is now just over 1,000 miles. I have not been going more than about 75 mph (also varied the speed quite a bit) on the highway and I have been gentle with the acceleration for the first 1,000 miles (break in period) since that's what the manual suggests.
In any case, that's my experience so far. I am convinced that this car does a fantastic job with gas mileage on the highway.

I do a lot of city driving - not so much on the highway but not a terrible amount of driving in general during the week.
It takes 3 days to go from 100% to 30%.
Oddly enough I feel my previous 550 got better gas mileage.

I am having the same experience.
I believe I got better gas mileage on my '08 S550 4matic compared to my '14 S550 4matic. I do a combo of city/highway driving with my average mpg on the '08 was about 17.5 mpg while my '14 is about 16 mpg with the same type of driving and same routes. Very interesting in deed. With the high highway numbers posted by some I thought it was just me that got "bad" gas mileage relatively speaking. Of course I could drive my '12 Ford F-150 and get 11 mpg so I should not complain to much.

I haven't done a road trip yet but I'm not close to 18 City, even using eco mode. The mileage on the window sticker is 17 / 26.
My 08 S550 definitely better on gas mileage in city driving and it did not have an eco mode!

I'm just curious. You guys that are not getting very good gas mileage (probably worse than the older S550) do you have the 20 inch wheels? If so, maybe that's the reason. Did your older S550 also have 20 inch wheels?

My '08 and '14 had/have the 19 inch AMG wheels that come with the AMG Sport Package.

My 07 had 19"
My 02 also had 19"
Both got SO MUCH BETTER gas mileage than current 14.
I feel like I fill up to 100% and perhaps 10 minutes later after driving a few miles, im at 95%. Then 90% when I park and I've only been on the road 15 minutes.

No the reason why bean is getting such great mileage is as he stated that he has does not go faster than 75mph. I do 75mph just on the on-ramp alone. I drove my last 4 tanks to empty and I drive it pretty hard. It says get 14mpg on average tank. City driving I get 9-10mpg.

Wheel size probably has some impact but as you stated, the type of driving one does seems to have a greater impact then it did on say my '08 S550 4matic.
I seem to get more disparity in gas mileage depending on if I am easy on the gas peddle vs. more aggressive driving. It appears from my experimentation that all highway driving and being easy on the accelerated can get gas mileage approaching upper 20s while my type of driving seems to get in the lower teens.
Guess I better try using the ECO button if I want better mileage---NOT!
I will just go through more gas since I love being aggressive with this car. Man I would love the S63 but the S550 goes like a bat out of hell if one drive aggressive with it. Using the paddle shifters reminds me of the time I did the AMG Challenge (now called AMG Academy I believe). This car is fast!
