Think about it before you buy. Too many excuse makers on here about driving style. The facts are this vehicle will not get the 24 and 28 advertised.
Our 2008 has 7500 miles on it and gets about 16 in City and 20 on the highway w/ cruise control.
Also, I had an issue w/ the rebate program that neither GM or the Dealer would take accountaiblity for....wont buy another GM after having done so for 15 years.
THAT IS THE REAL STORY.

i hear ya buddy and i feel your pain Having same BAD GAS MILEAGE problems with my brand new 2008 acadia received NOV 30 07. so far after 475 miles i am getting 9.2MPG city driving. i am not an aggressive driver. The gm service guy in brooklyn says he is getting the same performance with his own acadia. I have an appointment with dealer service dept. day after christmas. i had an occasional strange gas smell coming from the vents that would dissipate after a few seconds. but that problem did not return for over 2 weeks now. i found no leaks or puddles from the car. I DO NOT accept explanation of 16/22 MPG is only under "OPTIMUM" conditions. the 2008 EPA estimates are based on NORMAL usage, such as, air conditioning use, normal acceleration, braking, etc.. the car is wonderful otherwise. i wish someone can give me an idea as to why i am having such bad gas mileage???!!!!  i would like to give a heads up to dealer mechanic.
when you find out something...PLEASE LET ME KNOW! much appreciated.

I have had a Acadia FWD SLT 2 since April 2007 and have about 10,000 miles on it. I used to get 20-23/mpg hwy (70mph) and around 18 city driving 30 mph. I did the transmission update and not am lucky to get 18 hwy. I love the Acadia but wondered if anyone has got the decline since the transmission update?

I also own a 2007 GMC Acadia AWD and I consistantly get 24 to 25 mpg combined highway and city driving. I once got it up to 30 mpg on the hiway only. (60 mph and working at keeping the rpm down) My Acadia is now a year old and has almost 14,000 miles on it (it was #17 sold) I had the trans. upgrade and have not seen any difference in the mileage.

I have a very hard time believing 24 to 25 mpg in combined driving.

Once again, I made a 400 plus mile trip from the coast to the city, around town running errands, and back to the coast and averaged 25.1 MPG. My Acadia is a 2007 AWD SLT2. although there was only one person in the car, I had 6 cases of books in the back on the way up to the city. After I got home, my wife drove the Acadia to and from work (about 10 miles each way a combination of 50 MPH hiway and 25 tto 35 MPH through 3 small towns) and the milage dropped to 24.2 MPG. There is now 13,000 miles on the car and this is the milage that we have been getting since we bought the car. We do notice an drop in milage when we drive aggressivly or have a full load of passengers. I have in the past owned cars that were "Lemons", maybe this time it was my turn to get the "Diamond".

2008 SLT1 FWD 1st tank

1st tank on 2008 SLT1 FWD less than 200 miles on it getting 16.8 mpg doing the 15 mile commute to/from work. Previous car was a 2004 Suburban 2wd, which I could get 15 mpg doing the same commute. Considering it's the first tank and had alot of dealer lot standing on it, and that the mileage showing on the DIC has been slowly increasing the entire time, I figure I''ll get 17-18 doing this...
Also, given I could get 15 on the 'burb, when it was rated for 13 in the city (and spending hours looking at the inst mpg on the thing trying to see how to drive it to get all I could), 1-3 over city average seems reasonable.
Spend 4 years at 15 city 18 hwy, and 17 city anything more than 20 hwy seems wonderful. I guess the people hollering the most are those that went car to this thing, vs goliath to this thing...

2nd tank on 2008 SLT1 FWD with about 700 miles on it got 18.8 mpg doing the same 15 mile commute as in previous message. Average MPH was about 26. Mileage was as high as 21 at one point, but once I got to the weekend and started hauling family around to soccer games, grocery stores, etc, it dropped.
Anyway, overall the MPG for this thing is pretty good, especially compared to the Suburban I came from. Haven't had it on the highway for an extended period, so don't know that MPG.
AWD is going to be less. My wife has a 2005 MDX, which is AWD, and the way it works, from 0-15 mph, the thing is in four wheel drive mode. Once you get over 15, it switches to front wheel drive mode. Just having the connection to the rear wheels, whether it's active or not, is going to drain some power, and thus MPG. Where I think the impact is worse is over that first 15 mph. I would think the drag is much more when in 4WD mode, so if you're in alot of stop and go traffic, your constantly in that mode. I would think the AWD Acadia works in a similar fashion. On the highway, the MDX does pretty good, but in alot of stop and go, it's down around 14mpg...

My 2007's real world milage

Normal driving - 1/2 highway, 1/2 backroads to and from work = 19.5mpg
Highway - 22-24 (24 if I baby it, go the speedlimit, etc.)
Pulling a snowmobile on a trailer = 16.5 in trailer mode
Pulling two snowmobiles on a trailer = 13.5 in trailer mode
My Yukon got about 16.5 all the time. My Acadia has more horsepower than my 99 Yukon did and pulls the sleds better.

We just bought an 08 FWD Acadia and the first tank of gas we got 19.2 mpg! Combination of City/Hwy miles, live in MS so no mountain pulling! I have been very slow to take off and brake and I think that has helped alot too.
Hey, compared to some of these posts, I think that is pretty good!
