Gas was the last thing on my mind when buying this car but damn does it eat a lot. I've had the car for about 5 days and put on 100 miles mostly stop and go and at time letting it run when my friends were checking it out and I can see my MPG at like 10.5 at times. I thought Hummers ate a lot of gas but this is almost at the same level. Is this normal?

:P Let me just say welcome to the club. Yeah that is normal. im getting probably 16mph for highway and 9 for city. I notice also that when driving you can literally see the gas meter go down, make me wanna cry.

Seems low to me. I get 13 in town, as much as 21 hwy. Average is 16.5 over the last 2K miles, and I do enjoy the power especially since my '06 is no longer stock. Do you see a lot of stop and go traffic? That's a killer on the average mpg.

i was just commenting on same thing, tho i have the 02 NA S55.
funny thing, i actually got surprisingly good mileage on my 01 E55...so much so that i didn't even think much about swapping to heavier S-class.
surprisingly, the 400 lb weight penalty feels like it's about 4-6mpg difference in city and about 2-3mpg on hwy.
yes, i similarly see the fuel gauge go down, even as computer showing 14mpg.

DUH, just noticed you said mostly S&G over 100 miles. It's Ok, it'll come up a lot once you start moving. After all, it's a 500HP V8.

Bad on gas but gotta love it.

Actually, I find that it is not that bad at all if you don't push it. For instance, my M5 used to average from 22-28L/100 km in the city and 13.5 to 17.0 on the highway. The Merc is avergaing 18 - 22 L in the city and 12 - 13.5 on the highway... But then again, the weather is horrible here in Toronto. It has been raining the whole week + I already have my winters on, so I don't push it.... Hate the winter

I hope you were talking about the E60 M5. My E39 M5 did about 11-13 on the highway and 15-17 in the city. On the highway I could get as good as 9-10 if driving very gas savingly. The E55 is thirsty and does 12-14 on the highway and I have never seen a value below 11.8 whatever I do, City is around 18. My mixed average is 15.6. If it helps I have had the winter wheels on for 2 months and will have to have them until the end of April. The winter here is too long. Well if you can call 18 inch winter wheels at all...

I've noticed it really does get better mileage when in the comfort mode as opposed to sport mode....just not nearly as much fun to drive.

I guess if you aren't going to play for whatever reason, leave it in comfort mode and save a bit of gas.

I get 20 MPG in comfort mode on interstate traveling.

Funny thats exactly 11..8 l/100km I was talkinig about!!!

ATKM5

Yep, 2006 E60 M5...

What you don't know won't hurt you, as the saying goes. I too noticed the poor mileage, at first. Now I keep the display off the MPG screen. I only watch the fuel level to know when to fill up. Often, if I see it at 1/2 I will just fill it at that point. I am enjoying the car more. All of us can afford a little extra gas so why dwell on the point? I know one thing is for sure, if any of us has an opportunity to "punch" the car we will.

Right, Comfort mode =

Went out on a run for about 45min on the highway cruising the speed limit and I got 19.5mpg

That is pretty much what I get when I am conservatively driving on the HWY.

Timeless

Because it is SOOOOO hard to hit that one button for sport mode?

Comfort mode is for when I have clients/family in the car or trips on the interstate until I see something worth playing with.

True I was so tempted especially when all the other cars are passing me.
