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.

I HAVE BEEN LOOKING FOR A CROSSOVER FOR OVER A YEAR NOW. THIS SEEMED TO BE THE PERFECT VEHICLE, AS I HAVE A 2002 SUBURBAN THAT DRINKS GAS!! I AM REALLY DISCOURAGED THOUGH AS I HAVE READ ALL THE REVIEWS AND THE FORUM ON MPG. HAS ANYONE NOTICED ANY BETTER GAS MILEAGE ON THE 08'S? OR HEARD THAT THEY MIGHT BE TRYING TO IMPROVE THAT ISSUE? THANKYOU FOR READING!! DON'T KNOW WHAT TO DO?

Replying to: steve_ (Aug 02, 2007 11:27 am) "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. "

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. |
