Billy Bob Posted December 18, 2011 Report Share Posted December 18, 2011 I'm thinking about buying an AWD but am concerned about owners conflicting reports with fuel efficiency. Some claim 24-25 mpg while others report far less. My 02 Jeep Liberty gets about 21 on the hwy and I'd like to know if the AWD's 24-25 is valid.

wlepse Posted December 19, 2011 Report Share Posted December 19, 2011 with our 2011 SEL AWD I can get 24 on a pure highway ride driving ~65mph, no back roads no lights. Once you introduce and variability in speed and it drops to 19-21 depending on terrain. Quote Link to comment Share on other sites More sharing options...
mrdave Posted December 19, 2011 Report Share Posted December 19, 2011 Temperature (and winter gas?) seems to be a big factor. This summer I could get 25mpg fairly easily on highway trips at 70-75mph. Now I get about 22-23mpg highway. Quote Link to comment Share on other sites More sharing options...
11edgelimited Posted December 19, 2011 Report Share Posted December 19, 2011 Have only had my edge limited for a week and haven't been on the highway with it. But around town semi spirited I am seeing 19 mpg. so I have to believe you will see the same if not better than your liberty. Quote Link to comment Share on other sites More sharing options...
EdgeGermany Posted December 21, 2011 Report Share Posted December 21, 2011 Our average is 20 MPG with the 22" wheels 50% city and 50% highway mix. We change to 18" winter wheels yesterday and maybe it will become better. Quote Link to comment Share on other sites More sharing options...

It seems like the "ecoboost" engine has the best ratings for a 6 cylinder AWD vehicle.I'd say the responces sound encourgaging. Would you all do it again?

wlepse Posted December 22, 2011 Report Share Posted December 22, 2011 All the responses were from people that have 2011's so no ecoboost, just the standard 3.5l V6. Also the ecoboost is not a 6 it is an inline 4 with a turbo in the Edge, other models do have a 6 cylinder version but not the Edge. Quote Link to comment Share on other sites More sharing options...

You can't get the Ecoboost engine with AWD, and as welpse stated above the Ecoboost has 4 cylinders. Quote Link to comment Share on other sites More sharing options...
tmbubell Posted December 23, 2011 Report Share Posted December 23, 2011 Here is what i am observing 2011 Ford Edge Sport 3.7L- V6. AWD With 22" Sport wheels and tires on, computer says 13.9L/per100KM approx 509 KM Per tank on fill up. 50/50 Mixed Driving Freeway, rush hour crawl, city driving 15 fill ups averaging the same With 17" Steel Wheels & Snow Tires on, computer says 12.7L/per100KM approx 617 KM Per tank on fill up.

Same 50/50 Mixed Driving Freeway, rush hour crawl, city driving MFT was programmed with new winter tire size settings to keep speedo correct 7 fill ups averaging the same I am curious why met re-programmed for different size wheels. As long as overall Dia. is the same there should be no need to change the met settings. Are you able to make these changes yourself or do you have to go to dealer? I have 20" summer which are 245/50/20 and I am installing winter tires which are 245/60/18 both overall Dia. is 29.6". As for gas mileage I have the ecoboost on my 2012 I am averaging 25-29 us mpg in the city according to the onboard computer. On the highway around 58 mph I can get upwards of 37 us mpg but it does drop rapidly even for 60 mph. Quote Link to comment Share on other sites More sharing options...

The MFT has a section in it that the Ford techs can get to and reprogram tire sizes to keep your Speedometer accurate The standard 22" wheels come with a tire size of 265/40/22 The 17" steel wheels with tires are considered a minus size at 235/65/17 The diameter difference of this tire package is 4.36 % Speedometer difference of 4.551% too fast So if they didn't adjust for the tire size My Edge would be reading 60mph/100kmh when the Edge was really doing 62.7mph/ 104kmh The service manager explained it to me and it sounded like it was a simple drop down menu with a list of tire sizes to select from. This minus tire size wasn't in the MFT system and they had to download the update from Ford before programming it in my Edge Quote Link to comment Share on other sites More sharing options...
Scorpio Posted January 1, 2012 Report Share Posted January 1, 2012 Mine has improved from new with some break-in miles. In pure highway driving I'm now seeing 9l/100km (~26mpg US) with cruise set at 65mph, but that drops to just over 10l/100km (~23mpg US) with cruise at 75mph. Around town driving I'm seeing 12.5l/100km or about 18mpg. Not what's advertised but not bad for a heavy awd SUV. And very similar to what I'm seeing in our awd RDX as well.

blankster Posted January 3, 2012 Report Share Posted January 3, 2012 Keep in mind the Edges with 20" wheels have the same axle ratio as the sport - Not what the impact is with going to a different wheel size. Quote Link to comment Share on other sites More sharing options...

To explain: Going from the summer 22's to the winter 17's, if the speedometer/odometer is not corrected when you install your winter wheels it will read ~4.3% too fast. That means that when your speedometer reads 60 mph your actual speed will be ~57.4 mph. In other words, the actual vehicle speed will be slower than the speedometer reading. Now in the spring when you switch from the winter 17's to the summer 22's, the speedometer will then read ~4.5% too slow, meaning that when the speedometer reads 60 mph, the actual vehicle speed will then be ~62.7 mph. In other words, the actual vehicle speed will be faster than the speedometer reading. These figures can be verified here - LINK - Tire Size Calculator Not a big deal at all, but just wanted to keep anyone from getting confused about the entire "slower/faster" speedometer reading thing. Hope this information helps. :grouphug: Good luck. :beerchug: PS - Of course, on a side note, the need for any speedometer recalibration at all could have been avoided entirely by purchasing 235/70-17's (if available) instead of 235/65's. But that is another story. Edited January 3, 2012 by bbf2530 Quote Link to comment Share on other sites More sharing options...

akirby Posted January 3, 2012 Report Share Posted January 3, 2012 Miata.net looks correct to me. The math on the other one doesn't add up. 1 mile = 5280 feet x 12 = 63,360 inches divided by 91.2 (circumference) = 695 (not 716). Quote Link to comment Share on other sites More sharing options...

But that is another story. Hi tmbubell. :D Sorry if my explanation was a bit confusing. The way the 1010 TIre site displays the information can be confusing, which is why I normally use the Miata site. For example, with the 17's and an uncorrected speedometer, if your Edge speedometer displays 60 mph, you will actually be traveling at 57.4 mph, since the uncorrected speedometer will be reading too fast. So it was essentially correct when you first stated "Speedometer difference of 4.551% too fast". However, you then mixed up the numbers when you added, "So if they didn't adjust for the tire size My Edge would be reading 60mph/100kmh when the Edge was really doing 62.7mph/ 104kmh". If I am reading correctly, your explanation has the speedometer reading too slow instead of too fast. So as stated previously, when your uncorrected speedometer reads 60 mph with the 17's on, you will actually be traveling at ~57.4 mph (not ~62.7). I attribute that mistake to the slightly more confusing way the stats are displayed in the 1010 Tire site. Even putting the math errors of the 1010 site aside, they both get us to the same place, but in a different way. Overall, discounting rounding of figures etc., the Miata site is correct and (in my opinion) a bit easier to read and sort through. Again, sorry for any confusion and good luck. :beerchug: Edited January 3, 2012 by bbf2530 Quote Link to comment Share on other sites More sharing options...
