GMC Acadia Real World MPG

lukesdaddylukesdaddy Posts: 12
I am curios if anyone who ownes an Arcadia can post their MPG figures. I have been reading a lot of posts and what I am seeing is experiances all over the board from 12 MPG to 20+.

If you own an Arcadia, please post your experiance including whether you have 2 wheel or all wheel drive, type of driving you do (ie City highway)and whether you drive on hills very much. I live in very flat Florida and from what I seem to read, mountain driving is killing MPG on this vehicle.

Thanks in advance for your input.

    I've been reading a lot of posts on the Arcadia and it seems that people are getting gas mileage all over the board. From a low of around 12 to a high of 20+. Can anyone who owns one share their experience, what type of Arcadia you have (ie 2 wheel drive/ all wheel drive) and they type of driving you do? I do about 50/50 highway/city and was hoping to purchase a vehicle that would at least have a chance of averaging 20 mpg.

    Thanks for your posts in advance.

    Sorry it looks like my colums didn't post correctly but it's for a front wheel drive SLE.

    Best- 22.9mpg, Worst- 15.0, Average over 2150 miles- 16.8mpg.

    I've only got 1200 miles on my AWD Acadia but I doubt if you'll see 20 mpg with a 50/50 mix of driving. It takes gas to drag around two and a half tons. My last couple of tanks have been 18 to 20 with mostly highway and an average of 35 to 39 mph. My 2 cents.

    Thank you for the imput. Very helpfull.

    bought an 07' SLE 2-wd. MPG is nowhere close to EPA estimates on sticker. Wifes car, she drives conservatively and commutes 25 miles per day round trip to work. Occassional errand running on weekends. The car basically sits Mon-Fri except for work commute to/from. Have had since Late Feb, early March, MPG as averaged 18-19. Comment to dealer spurred a response about the transmission needing to be broken in, or reach some type of mileage level before optimal performance begins. I've never heard of this, then again I'm not a professional auto engineer.
  • I love the Acadia except for the poor gas mileage. I have not taken it back to the dealer concerning this issue; but will at the first maintenance period. My real world experience in the city (Houston) has been 12 MPG 100% city and I am not an aggressive driver. If I am on the highway 100% I can get 21-21.5. I would love to hear if there is anything that can be done to correct this problem. I have heard all the chat about mileage will improve after the break in period; but that is only after 500 miles, also have heard about reprogramming the transmission? I never would have thought mileage would vary by 30+% from the sticker? The V8 in my GMC Yukon gets the same to slightly better mileage in the City. Go figure

    It's almost impossible to get the EPA numbers. They are stated to be "for comparison purposes only". The test standard changes this year for 2008 vehicles based on a more realistic driving conditions and in general, almost all vehicles will drop by 2 to 3 mpg (much more for hybrids). The current system uses a highway speed of 55 mph. Modern speed limits are generally 60-75 mph, so we're driving much faster than what the standard is based on. Aerodynamic drag is the primary factor in highway mpg and it plays a much bigger part at higher speeds. There was an article a few weeks ago about a guy who drove the length of the Jersey Turnpike (or Garden State Pkwy, I don't remember) at 45 mph in a Camry and got almost 60 mpg! So if you want the highway numbers, you have to slow down to 55 or less. (Yea right!)

    After perusing many Acadia forums, it seems like you'll be out of luck on city mileage: the Acadia is a heavy car, and city driving will kill the mileage. For pure city driving, people are reporting no higher than about 14 or 15 with FWD. Where it shines is on the highway.

    Makes me wonder if a V8 would be more appropriate for this car: more power, and maybe similar gas mileage (for example, the 5.3L V8 Tahoe gets 16 city and 22 hwy, for a vehicle that weights about 550 lbs more than the Acadia).

    I just bought a 2007 Arcadia one month ago, mine is a 2 wheel drive also. I am so disappointed in the gas mileage. I once got 19 miles to gallon on the highway, but it usually is 16.5 highway and 13 in the city. The sticker stated 20-26 miles to gallon, even the comercials focus on the "great" gas mileage. I am so disappointed.

    FWD SLT2

    One was pretty much city driving....

    about 16mpg; averaging 20mph

    One was pretty much 70/30 hwy/city

    about 21mpg; averaging 40mph.

    VERYYY happy so far!!

  • donl1donl1 Posts: 112
    I hit 5000 miles on my AWD Acadia recently and with mostly highway driving I rarely see 20 mpg. Disappointed in mileage and power. Previuosly had a 06' 300C AWD and it got better mileage and the power was out of this world compared to the Acadia. :(

    Just got back from a weekend trip to Mobile, AL from Atlanta. The trip is about 350 miles one-way. I reset the mpg computer when I got on the freeway early Saturday morning. With the AC turned off most of the morning I got 26-27 mpg travelling between 65 and 75 mph. The combination of turning the AC on and one scheduled stop lowered the trip mileage to Mobile to 26mpg exactly when I got off the freeway.

    On the way back I got a later start so the AC was on all the way and I was carrying a medium sized freezer. With one scheduled stop, and some stop-and-go traffic in Montgomery, I still got 25.5 mpg (I again reset the computer when I got on the freeway in Mobile).

    A few notes...I was solo on the trip so there was no extra passenger weight and I have inflated my cold tires to 37psi. In 100 degree heat the highest it got was 41psi. I used cruise control when possible but the hills caused the transmission to downshift, I felt, too aggressively so I took over whenever necessary.

    In conclusion, under the right conditions, the EPA highway estimate is attainable with not too docile driving.

    Really appreciate all the input from you guys. The dealer keeps calling to get me to take one of the few remaining 07, but I was holding out for better terms on 08. Now reading about the poor MPG I may have to rethink even buying the Acadia. Too bad! Liked the ride, but MPG is important as 60% of my driving is local and as we all know gas isn't going down.
  • donl1donl1 Posts: 112
    If you are looking for gas mileage you might want to look elsewhere. I have an AWD Acadia and power and gas mileage are not its strong suits.
  • theroguetherogue Posts: 5
    I guess some folks just don't believe the rest of us.

    two more tanks through ours. Averaging almost 21mpg (hand calc'd and lie-o-meter), with an average mph of 32. That seems to me to be pretty good numbers for a big rig like these in city-type conditions. Can't complain about the power (needs the whole downshifting thing fixed though!) and that's coming from an 06 Ford Mustang.

    Yes, I'm in a FWD; but honestly, who NEEDS an AWD? :confuse: :confuse:

  • sabbabasabbaba Posts: 7
    WOW! I never considered that there could be such a difference between the AWD and FWD. I don't care either. The NY roads are always driveable the day after the snow anyway. I work out of my house so if I hear snow I don't go. I would buy for sure at 21 MPG.
  • bopper1bopper1 Posts: 1
    I have the Acadia SL 2 AWD.
    Driving 75 to 83 mph, 22 mpg.
    Drivng around 60-65, I get 24 mpg. Watch tach and try to keep it under 2000 rpm's. 6th gear (over drive) kicks in around 58-60 mph.
    When driving over mtn. passes manually put the transmission in 3rd. Keeping tach under 3,000 rpm's I get 22 mpg. This 3rd gear is great for going up and down steep hills.
    Just around town, doing errans, I get 18 mpg.

    On Sunday I drove about 260 miles round-trip to drop off my son w/ his grandparents. On the trip out there I did everything I could within reason to maximize my fuel economy according to the DIC. This included drafting behind larger vehicles and a speed generously below the allowable limit (60 in a 70).

    On the way back I just set the cruise control at 70 and let it do it's thing.

    All miles for both legs of the trip were highway with light traffic.

    Leg A - Avg. Sp.: 60.7, Avg. Eco.: 28.1
    Leg B - Avg. Sp.: 71.3, Avg. Eco.: 24.7

    While using cruise control, it seemed that most overpasses would cause the transmission to down shift to maintain speed. I avoided this by using the Set + / - buttons. Approaching an overpass I would kick the speed up about 2 MPH. While crossing the overpass, I would decrease the speed by 1 or 2 MPH as the grade increased. This kept the transmission in 6th.

    I've got an AWD Acadia with almost 9K on it and I don't remember the last time I got 20 mpg. Wished I'd have got one of those magic ones that get 25. ;)

    Until GM reduces the weight of the beast by 500lbs. gas mileage will not be the Acadia's strong point.
  • wlbrown9wlbrown9 Posts: 867
    I don't think 500 pounds would make that big a difference in gas mileage, more in stop and go, less in hwy cruising. Compared to previous gen. GM SUVs I would guess the 6 speed tranny and some of that would make more difference than just cutting some weight.
  • steverstever Posts: 52,462
    An extra 100 pounds in your vehicle could reduce your MPG by up to 2%.
  • wlbrown9wlbrown9 Posts: 867
    Okay...up to the complete statement...Up to means from 0 to 2%...larger vehicle, several hundred pounds. Maybe 4% reduction. Possible reduction of about 1 MPG based on EPA estimate of 25 MPG hwy.

    "Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones."

    Now look at the possible saving of driving style, up to 33% could be as much as 8 MPG. Now we see why some folks get better mileage that others.

    "Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. "
  • steverstever Posts: 52,462
    lol, like all the aftermarket gizmos that say "up to ten percent better mileage and horsepower."

    Point taken, but 500 pounds is a pretty good chunk any way you slice it.
  • Friend of mine has ordered a 2007 FWD Acadia. Should get this month. He says a friend of their's has a 2007 AWD Acadia which gets 24mpg in a mixture of city and highway driving. He thinks that he might get 25 mpg because he has FWD instead of AWD. I'm stunned to hear such great mpg figures from a big SUV.
  • dardson1dardson1 Posts: 696
    If you watch the Odyssey or Sienna threads (huge and heavy cars there days), those who post complain about about mid teens city and low 20's hwy. Whatever the numbers say, pushing any heavy vehile around takes fuel. As far as I know, no one has changed the laws of physics. I'd say if anyone can manage 16-17 around town and anything close to mid 20's in GM's new disguised minivan he is getting about all that's there.
    In the old days we drove 2100lb, 4cyl, 92hp imports that did 0-60 in 15+sec and got 22 around town and /30ish highway. The cars were loud, relatively uncomfortable, and very small. Turning on the AC robbed a ton of power and often pushed the temp gage too high.
    Chill, folks! You're getting your cake and eat it too. These new vehicles are quick, huge, comfortable, luxurious, quiet, and not all that much less economical than a mid 70's Toyota half the size and weight, lol.
  • Well FWD must make all the difference in the world because in the 3.5 weeks I have my '08 AWD SLT-2 Acadia, I can't do better than 16-17 MPG and this is not in-town driving, but basically 90% highway driving and averaging 60-70 mph. Yes it's a heavy vehicle, but nonetheless, still quite disappointing. Between 10/23/07 and last Saturday, 11/10, I've put $400 in gas in that thing. I didn't realize it would be that much of a fortune to keep it running. I bought it with the notion that I would get at least 20-21 MPG. Again, not happy. It kind of takes some enjoyment out of having the vehicle. On another board someone recommended me getting a small car for my daily commute and keep the Acadia when I need the room to haul the kids and cargo. Having two cars just for me is not in the equation!
  • Drove from Houston to San Antonio and back this weekend. On the drive to S.A. the Acadia averaged 21.8 (strong head wind).

    On the return trip, the average was 23.8----calm winds. Speed was set at 73mph on both legs.

    The mileage on the vehicle is just over 1,000 miles---------6 weeks old.
