Acura MDX MPG Real World Numbers



  • hpowdershpowders Posts: 4,269
    Show me similar stats for the 2007 MDX. That's what I was referring to.

    I don't see anyone getting much more than 21 mpg and that's pure highway driving.
    Probably more like 15-17 mpg in combined driving.

    Several auto press test-drives list the mpg of the 2007 MDX as a negative. Still a lot better than the Q7, but not great.

    How come nobody in the auto press has been able to achieve your results? I mean getting 31 mpg with any MDX would have been headline news. Are you questioning their testers' driving skills too?

    Don't show me stats for when the MDX is coasting down Mt. St. Helens with a 100 mile wind gust at one's back. Anybody can create a temporary artificial situation.

    Nobody in the real world (who has come forth to write about their experiences) in normal city and highway driving is getting 28-31 mpg with the 2007 MDX.

    Have a Happy New Year! :)

    After 1000 miles on my 07 MDX, I can say that it's about 19-21 on freeway & around 17 city. I have noticed the Trip computer showing above 25mpg a few times on freewyay.

    Mileage readings changed dramatically after 600 miles on the car..did anyone else notice this?

    Hi Hpowders:

    Sorry, I don’t own an 07, we own an 03. Those drives were for round trips and I don’t think we have a Mt. St. Helens to coast down w/ a 100 mph tail wind and then drive back up with another 100 mile tail wind from the other direction for the round trip segment. At least not in the Chicago area the last time I looked ;)

    Would you like to drive an 07 MDX over to my home and I will punch out 30 + out of it for you too? Pretty easy to do if you care to learn.

    Nobody in the real world (who has come forth to write about their experiences) in normal city and highway driving is getting 28-31 mpg with the 2007 MDX.

    If I owned an 07, I would :D

    Good Luck and Happy New Year!

    Hi, Wayne!

    I think it would be much more helpful if you were to provide some substantive details about how you achieved those mileage numbers rather than taunting other members with extraordinary claims only to entice or lure them into visiting your own site with those links.

    "Real world" means just that. What the typical driver is getting. And for the 2007 MDX, it falls in around 17-19 mpg for mixed commutes with a top of 22 mpg on the highway.
  • I noticed a marked improvement in fuel economy from 250 miles to 700 miles. Now, it's averaging about 20.

    We do not own a 2007 MDX (neither do you I assume), but I'll nontheless take on your cynicism that anyone can achieve better than the highway EPA estimate on the 2007 MDX when cruising at highway speeds. I have kept detailed mileage logs for all of my vehicles. I also travel regularly 370 miles each way to our second home. Virtually all highway, including 150 miles of PA Turnpike which includes some significant hills and grades. I average 65-70 mph with 2-3 rest, lunch or bathroom stops. Here are actual results:

    1995 Nissan Maxima SE 5-speed: EPA 22-27; actual MPG: 27.8 to 30.1 estimated average 28.5.

    2002 Honda S2000: EPA 20-26; actual: 28.8 to 32.5. Estimated average 31. (28.8 was with the top down, all others 30+).

    2004 Acura TL 6-speed: EPA 20-29; actual 28.8 to 32.1. Estimated average 30.5.

    2005 MDX: EPA 17-23; actual 22.5 to 26.4. Estimated average 24.5.

    2005 Porsche 911S Cab: EPA 18-25; actual 25.5 to 28.1. Estimated average 26.5.

    In all of the above cases, my actual highway fuel efficiency for straight highway "cruising" is higher than the EPA estimate. And this is not babying the car at 55 mph downhill downwind, but similar 370 mile trips at 65+ mph, with grades.

    I think your cynicism of inkyofok's claim to average 25 mpg at 65 mph cruise in the 2007 MDX is misplaced. The fact that the 2007 V6 has a bit more horsepower than the previous model is insignificant to highway cruising at 65 mph. It's no heavier and perhaps a bit more aerodynamic and the added power actually helps maintain speed on grades. As a matter of fact, we only averaged 19 mpg on our routine trip with our old 1996 Isuzu Trooper 5-speed with 190 horsepower. It had to be downshifted constantly to handle the Pa Trunpike grades.

    Tidester: Hopefully this meets your request for "real world" data. But I think your indirect defense of hpowders was also a bit misplaced. I was polite in my response, but someone that states "I don't believe you" as much to say "You're lying" is apt to get a punch in the forehead from me in person. ;)
  • tidestertidester Posts: 10,110
    But I think your indirect defense of ...

    That was neither my point nor my intent. Even your top MDX mileage (26.5 mpg) is 5 mpg less than the claim made by the original poster (31-33 mpg average). It would certainly be interesting to learn how that was achieved without being enticed to go elsewhere for the information. :)

    I have no problem with the data. I just want to know how it was done.

    When someone claims 31-33 mpg average in the "real world" for a vehicle as big and heavy as the MDX, I have the right to challenge his credibility.

    The host asked him to provide his methodology. So far, nothing but silence in response.

    I have an 06 Touring, and since the wife and I work within 2 miles of each other, we 'share' the car a lot of times.
    I notice on the highway, she has this odd habit of constantly adjusting her pedal pressure.
    On-off-on-off-slightly back on-off-on-... drives me bezerk!!! Ugh, I hate what she drives LOL

    Anyway, when I have the car, I'm in the area of 23.8 MPG average.

    When she drives, it's an average of 17.

    I drive more aggressively than she does, but I don't fiddle with the pedal as she does.
    Something as little as that makes a big difference.

    I have never gotten the MDX above 25 MPG average for any real amount of time.
    Maybe a half mile down hill, but that's about it.
  • habitat1habitat1 Posts: 4,282
    And, may I remind you, you started this off with:

    "The only way you can maybe get 28 mpg with the 2007 MDX is if you remove all the seats, have a fraction of one gallon of gas in the tank, fill the tires with helium and have a category 2 hurricane following from behind.

    In other words, I don't believe you."

    The poster you challenged qualified his MPG experience as 28 mpg at a 55 mph steady cruise and 25 mpg at a 65 mpg steady cruise.

    Although I would fall asleep or be run over from behind trying to test a 55 mph cruise on our MDX, the 25 mpg at 65 mph is completely consistent with our experience, using cruise control for long highway trips.

    LOL, My mother-in-law must be from the same gene pool as your wife. After the second automatic transmission replacement on their Saab, the mechanic went out with her for a drive, called my father-in-law and told him to either buy a manual transmission (w/o a torque converter) or divorce her. Apparantly, doing the herky jerky on the gas pedal is not only bad for fuel efficiency, it's one of the worst things you can do to an automatic transmission.
  • scottm123scottm123 Posts: 1,501
    Great, as if I didn't have enough worries with the impending torque converter issues on the MDX as it is. :sick:

    Hi Tidester:

    Because posts get buried here at Edmunds, you cannot do much with a 15 page post and have to post it again and again and again over the years. When I link Edmunds from CleanMPG, it can be found quite easily … I asked Sylvia to build a Mileage DBase years ago and of course none can be found :(

    As for the details, Google my name and you will find all kinds of details from tens of other sites on how you get 30 + in an MDX, 60 + in an Accord, 120 + in a Prius II and 195 + in an Insight ... Those are long distance segment peaks however.

    Good Luck

    The "MPG-Real World Numbers" discussions constitute a database.

    you cannot do much with a 15 page post

    The question was how do you achieve the numbers you claim? 15 pages and dozens of sites sounds way too complicated but a "Reader's Digest" version here will do nicely. :)

    Hi Tidester:

    Real word FE discussions in a forum do not represent a Mileage DBase. Click the link in my sig and you have a real mileage DBase.

    These links will be buried in this forum within a matter of weeks but here you go even though Edmunds hates for me to link to other sites :(

    Beating the EPA - The Why’s and how to Hypermile.

    Adapting Basic Hypermiling Techniques to the HCH-II

    Hypermiling the Ford Escape Hybrid ...

    Pulse and Glide plus Warp Stealth in the Prius II for maximum FE …

    External Factors Affecting Mileage, or why “YMMV”

    This is how you receive > 30 mpg from an 01 – 06 or the new 07 MDX’s. Whether one chooses to do so is entirely up to him or her.

    Good Luck

  • Tidester,
    Kudos on being so diplomatic with this guy. I look to this thread to see how my mileage compares w/ other owners of '04 and '07 MDX and have offered my own suggestions from time to time(e.g. the "Tornado"). Is there no rule that you can't have a link to your own website on these threads? I get enough garbage from infommercials and junk mail.
  • tidestertidester Posts: 10,110

    Well, this IS a Forum! Perhaps you missed the handy search function located at the top of this page. I notice your forum has one too. :)

    Let's take the general discussion over to Fuel Economy: Most bang for your buck since your points are not really vehicle specific and you've been given more than adequate opportunity to promote your own site - which, BTW, is not the purpose of THIS Forum.

    Thanks for your input, Wayne.

    Yes, we do have such rules but we're progressing toward amending them. Think "kinder and gentler!" :)

    Links will be allowed if they are directly pertinent to the ongoing discussion but chronic linking to or blatant promotion of other sites will remain unacceptable.

    And don't get me started on spam! :mad:

    Thanks to you, also, for all your comments!

  • Have had my 07 MDX just a little over 2 weeks. Got 20 MPG on trip home from dealer, about 75 miles on mostly secondary roads and being very conservative with the throttle. Since then all driving has been mixed city and freeway driving. It seems to be settling down at about 18.1 MPG. I am sure that if I were agressive with that 300HP mill, I would see that number drop dramatically. Hope to see MPG increase after the 1000 to 1500 mile mark.
