    Your average speed of 70 mph far exceeds the parameters of the government test procedures. If you check out and look at the highway testing procedure, you will find a test cycle that never goes above 60 mph and does that for only half the ten mile cycle, and has an average mph of only about 48 mph for that entire test.

    If you were to drop your top speed down to no more than 60 mph, you would likely see a much more favorable number, in my opinion, and the government's, which actually does the economy testing, not Hyundai.

    Amen brother! By the way, has anyone used the replacement gadget for a spare tire?

    If he travels 70 mpg he should at least get close to the advertised gas price. I got 33 on my one trip with the Elantra. We should be glad at least for this.

    First run to work this morning since I picked up the 2012 GLS last night. Reset the MPG about 1/2 mile from home.

    1.5 miles 50 MPH speed limit
    6 miles 40 MPH speed limit
    4 miles 45 MPH speed limit
    8 miles 65 - 55 MPH speed limit expressway
    1 mile city streets then up to 3rd floor in parking garage

    I usually don't hit too much traffic, had to slow way down one time on the expressway. I did get it up to 70 when I first got on the expressway for a minute. I drove pretty easy on the throttle today with ECO mode on.

    39.3 indicated by the time I parked in the garage. first 19.5 miles until I got off the expressway I was indicating 40.4 MPG. NO A/C this morning. I will not reset until I get home to see what the round trip holds.

    I think this is about best case. I think the average would drop down to around 35 if I do a week long test. Startup and initial run up to speed will drop it down some, plus every stop light I have to slow down or stop for will drop it some.

    I'm happy with mine so far.

    how many miles do you have on the car thus far?it usually takes about 5000 miles for a brand new car to get the advertised gas mpg.
  • 40 MPG A Lie 2011 Elantra by klintlwatkins:
    I've been driving this car to and from school via Highway. Average speed around 70 mph. I ve yet to get ANYWHERE near 40 mpg. More like 30 mpg. This car is a total sham!!!!! My first and last Hyundai!

    If your average speed is 70 as you said, you are exceeding 70 much of the time. Not a recipe for best fuel economy on any car.

    Also, on a "huge downhill slope" you will get much better than 40 mpg, on instantaneous readout. Even on larger, thirstier cars I get 60+ mpg on huge downhill slopes. The trick is to shout "Whoo-hoo!" as you coast down (in gear) enjoying that super-high mpg. :D

    If you are depending on 40 mpg for your budget, I recommend you start driving with a focus on fuel economy. Then if your daily commute is highway and not too many stops, and you stick to the speed limit and use a light foot, you should get real close to that 40 mpg. But it's not a "gimme", that will happen no matter how you drive.
  • Okay, time to add my two cents here. I've had my 2011 Elantra for 6 months now, I have 5800 miles on it. I live in northern VA, near DC so sometimes I'm in stop and go traffic a lot. Anyway, it really depends on how you drive the car, weather conditions, traffic conditions, etc. No one here is going to get 29/40 every single time. My parents live down in Williamsburg, about 2 1/2 hours from me. When I go visit them, right before I get on the interstate I fill up with gas. I reset my trip odometer (which also automatically resets my MPG on the computer in the car) and off I go. My average speed on the interstate is 70-80MPH and within about 25 minutes or so, I'm averaging 41MPG.

    Now, let's say I had just half a tank of gas and at the time just averaged around 26 MPG. Even if I jumped on the interstate and still drove 70-80MPH, I would probably not see 41MPG.

    There are so many factors that come into play with this MPG nonsense. Sure, sometimes it's lower then what I want...sometimes, like now, it's much higher (32 MPG, but spent a lot of time on the highway). All I know is that it makes a lot of my friends incredibly jealous when I tell them my average MPG, and the fact that I only fill up once every 8 or 9 days, and when I costs me just $35. I have a fantastic car...if some of you guys want to constantly complain because you aren't getting the EXACT MPG that you were expecting, then fine, so be it. Trade in your Elantra for something else, quit whining, and move on.
  • I got a flat tire a couple of months ago, but I didn't use that gadget thingy in the trunk. I've heard that it can permanently damage the tire. So, I had to call AAA and have them tow me...ended up having to get a brand new tire. Grrrr!
  • rudy66rudy66 Posts: 26
    Thanks for the lecture but last time I got 21 mpg, city driving, but, for the whole tank of gas, trying to drive economically. My Accord did better.
  • steven39steven39 Posts: 636
    i think what a lot of people have to realize with a brand new car is that you are not going to get the best gas mileage until the car is fully broken in and you have atleast 5000 miles on the odometer.this was the case with my girlfriends 2010 chevy malibu which she purchased brand new.when she purchased the car the gas mpg wasn't great but then when she hit around 5000 miles it improved greatly.there is no brand new car out there that is going to get the posted mpg until the car is fully broken in and has accumilated some miles on the odometer.this according to a mechanic friend i know.
  • You're welcome. :) And if you are only getting 21MPG city driving, then it's the way you are driving it.
  • My last 4 cars averaged 10-15% over the highway average MPG & that was from new. If you don't think high MPG, you will get less MPG. After stating the vast importance of careful driving, I do note from my v. accurate line graph from my gas mileage accounts, that MPG does go up after a period of time. However, it is very very small amount, compared to actual careful careful driving.

    Hills, & mountains kill MPG, but you can learn to reduce those loses. Its good to keep the tires pumped up (more than recommended?). However, people pumping them to mid-40 PSI & higher must be the hyper milers, & its too high, specially if you want to stop before running over people. Also, even my moderate over-inflation, seems to be leading to my tires wearing just a fraction too much in the center. However, I drive a wonderful CVT transmission, which theoretically eliminates transmission jarring & tire flex & my average OE tires look like they will exceed 60000+ miles.
  • Just finished my first tank in a brand new 2012 Elantra GLS. This is the fourth Hyundai I have owned and I still of a 2005 Elantra GLS. I have stuck with Hyundai because they make decent commuters and I get a lot of miles out out them. My 2005 Elantra has more than 150K and is still going strong, not a single problem so far.

    However, my first impression with the new Elantra is that gas milage is nowhere near that advertised. I commute 70 miles a day back and forth to work. 75% of that is highway. First tank averaged 28MPG. That is worse than my 2005 Elantra which averages 30. I babied the throttle the entire tank all because I was expecting to see great numbers. It didn't happen.

    Given that it was the first tank, I expect there may be some small improvement. However, initial break in does not typically return more than another 10% in mileage. As a loyal Hyundai owner, it is sad to say that peoples concerns about the vehicle performing well below the advertised MPG are well founded. It is even sadder to think that after all the hype about mileage, the vehicle performs no better than the 2005 model which gets the same or better mileage when driven much more agressively.

    Don't worry as this is with first tank. You'll definitely see improvement in this figure. I own 2011 Elantra and I have now 7500 miles. I got 26 miles per gallon on my first tank. I was getting 28-30 within first 1500 miles. I am currently averaging around 32-33 miles per gallon with 45 miles everyday commute back and forth (60% highway). Best I have got 36.5 while I was commuting 120 miles everyday (Through Manhattan Traffic) initially. The only thing I didn't like about this car is "Suspension". I drive 2005 corolla too and which has far better suspension than this. Best of luck ahead.....

    Bought in January of 11. Elantra 2011 limited

    Over 12k miles in winter and summer conditions. Majority of driving is 75% highway.

    Average over life so far is 30.2mpg. Worst tank 26mpg in snowy conditions. Best tank 37 on a long highway stretch of 325 miles, and that was going 75.

    Average gas cost in Missouri has been 3.33$

    Mpg drops dramatically in typical city driving. Average for city for me is maybe 26

    Anything over 65 impacts highway mileage. I could have probably gotten 2mpg better on that highway stretch 37mpg mentioned above

    So far only saved 200$ in fuel costs over my 2001 Passat

    EPA estimates are wildly inflated for the typical driver. I know some hyper miler types have done that but everyday drivers will not.

    Trip computer estimates are always off by 1-2 mpg. Always calculate actual mpg

    Would I buy another? Not sure. The car is great but Hyundai is selling it on the fact it has great mileage. I averaged more with the Ford Focus hatch which was a rental car we had for 2k miles this summer

    I purchased a 2012 Elantra Limited about 3 weeks ago. I had been car shopping for a high mileage car because I do a lot of highway driving. I've driven just under 500 miles so far and have yet to come anywhere near the promised 40mpg. At least according to the car's own mpg indicator. I haven't yet actually done the manual mpg test one does when measuring between fillups.

    I'm not a heavy-footed or aggressive driver.
    Most of the highway mileage is over flat roads and I generally set the cruise at 65 - 70 mph.
    With the Eco-button engaged, the highest mileage I've gotten so far is 31mpg and it usually hovers around 27-8mpg. So what gives? What is the magical forumula to get 40mpg? Does one have to be coasting down hill the whole way?

    It seems to me to be a HUGE issue if there is so little consistency. And I'm thinking perhaps this advertised 40mpg amounts to a false claim. I'm really upset because I could have purchased a car like a Honda or a hybrid that actually gets the mpg they claim. On the MPG promise I'm feeling duped and upset. :mad:
  • There seems to be a lot of contention on Hyundai's mpg rating, so why isn't this being tested and reported on in the professional car reviews? It is, afterall, Hyundai's primary selling point, so why not look at it?
    If most owners on average are actually getting closer to 30mpg from their Elantras, then it sure seems that when considering a new car purchase, they might have considered a whole lot of other cars in that 30 mpg category that would be competitive with this car.
  • You are thinking that the advertized 40 mog is a false claim. Hyundai is only reporting the results of an EPA test. How can this be a false claim? Your gripe is with the EPA not Hyundai.
  • backybacky Twin CitiesPosts: 18,907
    You are setting cruise control on a flat highway (no stops, right?) at 65-70 mph and usually get 27-28 mpg? I'd take the car back to the dealer if I were you because there's something wrong with it. I used to get 25 mpg in my 4000 lb. V6 minivan at 65 mph cruise, and have gotten around 30 mpg in a V6 sedan like the Sonata or Impala under such conditions. In the 2011 Elantra, I got 40 mpg in those conditions, and 33 mpg in mixed driving in urban conditions.

    Since the cruise is on, it's not the driver. The road is flat, so it's not hills or mountains. It's not winter yet. There can't be a really strong headwind all the time. I'll assume you took care in measuring the fuel you put into the car. So 27-28 mpg as a usual circumstance is really odd. You should probably run a few tankfuls to make sure, but if mpg continues to hover around 27-28 under the conditions you described, that's just not right and not anything like I have experienced with this car.

    If the EPA is, in fact, allowing these discrepancies in real vs. reported mpg then that undermines the whole system. There IS a discrepancy as more and more new car owners seem to be discovering and the differences are far too large to be explained away by driving/terrain variations alone.
    I can only speculate why the EPA would do this, but maybe they are being lenient to sweeten the current trade deal with S.Korea, just announced yesterday.

    The highway/cruise control driving situation is around 32mpg. The 27-28 was the average for a more mixed driving situation (highway 70%, in town 30% approx). This is according to the car's digital mpg indicator. I will have to do the fillup to fillup real test as well to get a completely accurate number. That will also tell me if the car's digital system is on the mark or is lower or higher than my findings.

    Yes I will definitely take the car back if this continues to be the case. However, from what I've read here I'm not alone.
  • I can only speculate why the EPA would do this, but maybe they are being lenient to sweeten the current trade deal with S.Korea, just announced yesterday.

    Wow! Now we are headed down the conspiracy trail.

    Please read carefully from the EPA fuel economy website. Their fuel economy test is not a guarauntee of results merely a means of comparison.

    Why not? Plenty of precedent for that. And the U.S. is pretty desperate to create new jobs and manufacturing here, so they have incentive to be lenient in order to give new business ventures a foothold in the market. Not saying that IS the case here as I'm not privy to that information, but it falls pretty easily within the realm of possibility. At the very least, I do expect that this issue will grow and get louder as word of mouth gets around, which will not do Hyundai or the EPA any good. People don't like to be duped, and especially with such a costly item as a new car and tighter budgets where fuel economy is a big deal.

    Isn't it true that the government testing is done on a track and the car is in some way striped down? -- maybe even with no body? This sounds crazy I know but I have heard it. And thanks for saying that variations in our driving are causing poor MPG.

    Of course some drive more aggressively and some live in areas with steep hills, but on flat terrain, making a concerted attempt to attain the advertised mileage, should yield somewhat reasonable results. But many of us are not getting this result. The car is nice but some individuals (not me) actually bought the car needing better gas mileage because of their budgets.

    Nope, here is how they are tested. All cars go through the same process and procedures, no conspiracy involved!

    I'll have to put in my 2 cents worth here. Some thing is wrong here. We have a Sonata which is a heavier car with a more powerful engine and I can blow away your reportred highway mileage and at least meet your conbined mileage.

    The last car I drove was a 2000 Elantra Wagon and it could get about 32 MPG highway. I can't think that they didn't improve the mileage since 2000.

    Well here are some counter claims relative to the veracity of gov mpg ratings
    for anyone who would like a different perspective on that: - - - stimates-feature

    To pretend that all these foreign trade deals are pristine, above board business transactions is just naive. I'm not suggesting the scenario I proposed is true in this case, only that it is entirely possible and is common practice. And EPA test practices leave lots of fudge room too.
    It seems there is also a campaign to convince people that these
    anomolies between advertised and real mpg is due to their faulty driving.

    Yes I agree. Something IS wrong with this picture. And if you've been following this thread and others like it on the internet, this issue is being vocalized by more and more new car owners.

    In your original post, you said:

    Most of the highway mileage is over flat roads and I generally set the cruise at 65 - 70 mph. With the Eco-button engaged, the highest mileage I've gotten so far is 31mpg and it usually hovers around 27-8mpg.

    Now you are saying:

    The highway/cruise control driving situation is around 32mpg. The 27-28 was the average for a more mixed driving situation (highway 70%, in town 30% approx).

    Which is correct?

    27-28 mpg in mixed driving on a new engine is not too bad, IMO. If it goes up only 10% after break-in, now you're at 30 mpg mixed driving. And who knows how many stops, how much idling, how much stop-and-go driving is involved, compared to how the EPA test is done? There's a reason the EPA states, YMMV.

    But 32 mpg on cruise at 65-70 mph on a flat road seems low for this car. I have exceeded that in my wife's 2007 Sonata that is EPA rated only 30 mpg on the highway. My 2010 Sentra will get upper 30s (close to 40 @ 65 mph) under those conditions, and it's only rated 34 mpg highway.

    Please try this test and tell us the results: pick a relatively flat stretch of highway on which you can maintain a constant speed. Set tire pressures to at least factory spec. Reset the mpg meter. Set the cruise at the speed limit (or 70 mph, whichever is lower). Drive at least 10 miles, turn around and drive in the other direction (again on cruise). And see what the average mpg is. If it's not at least upper 30s I'd be surprised.
