#14 of 61 Road Trip Gas Mileage Report SLT1 FWD by jlaszlo Jun 18, 2007 (9:38 am)
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.
#16 of 61 Having Second Thoughts by sabbaba Jun 19, 2007 (7:34 am)
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.

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. Replies to this message: therogue (Jun 19, 2007 7:33 pm) sabbaba (Jun 20, 2007 1:42 pm)

Replying to: donl1 (Jun 19, 2007 3:13 pm) 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?   TR Replies to this message: sabbaba (Jun 20, 2007 1:42 pm)

Replying to: therogue (Jun 19, 2007 7:33 pm) 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.
#20 of 61 MPG by bopper1 Jul 07, 2007 (9:25 am)
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.
#21 of 61 Recent highway MPG by sboyd1 Jul 31, 2007 (1:30 pm)
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.   Results: 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.
