Hyundai Sonata Real World MPG



  • Sorry--not 5000, but 500----would need to be going in lots of circles to hit 5000 miles from MD to NJ......

    Just bought a 2012 GLS with 205 65x16" tires and noted the GLS has final drive ratio of 3.25 while SE/Ltd have 2.89 with 18" low profile tires. No clue yet about RPMS at highway speed. hoping for 2000 RPM at 70 to get the 35 EPA number. anyone out here have any experience with RPM at highway speed?

    We just returned from first highway trip with 2012 2.4L GLS. Mileage in town has been 22-24 but highway was outstanding. 38 at 67 MPH per computer and at 70-75MPH drops down to 35-36. Car not even broken in.
    have not done manual calc but computer seems close.
    Hills have noticeable negative effect but speed is the biggest variable. At 65 MPH the mileage is phenomenal IMO. Shifting on hills is very smooth - no searching as on some 6-speed automatics. 2.4L and 6-speed very well mated for the car's weight. We also got the GLS with PEP ($750) to get the alloy wheels but avoid the low profile tires. The 205 65 R16" tires at 33 # of air made for a firm ride with some bouncing on bumps but overall a very well mannered car and the MPG was right on the EPA estimate at 70MPH
    Great car and even greater value in one family opinion.

    " No clue yet about RPMS at highway speed. hoping for 2000 RPM at 70 to get the 35 EPA number. anyone out here have any experience with RPM at highway speed?"

    I was unaware that the Hyundai GLS didn't have a tach. If that is indeed the case, I would suggest you get a ScanGAuge 2 and plug it into to the OBD2 port under the dash just in front of your knee.

    Everything you ever wondered about your cars performance can be set to display. MPG's, Tach, battery charge, gallons used, on and checks the fuel used 2wice every second, and the tach read out is dead on.

    The GLS does have a tach.

    longo: what I meant was we had not driven the car on the highway yet. Just got back and posted message on MPG. Outstanding on the highway with 2000 RPM (it does have a tach) and 67 MPH it got just under 38 on 100 mile trip. 10% speed increase drops it to 35 that makes sense. Great car so far!

    I've had my hyundai sonata for a year now. it gets the expected gas mileage if you drive at 2000 rpm on the highway. however as hard as I try I cannot get the expected gas mileage in the city. my car has 15,000 miles on it now and I've taken several trips. I do my best to keep the rp m's under 2000 rpm without causing an accident but I cannot get the 25 miles per gallon in the city. if anyone has any ideas I would really like to know because this is lori my overall gas mileage. so far I like the car in the way it drives but with gas prices going up, I may have to switch to a vehicle like the toyota prius. has anyone found the secret to the city gas mileage I would really like to hear it.

    We have anew 2012 Sonata GLS and are very impressed with the mileage so far. 22-26 in city with the extremes being all stop and go (22) up to 26 with streches including steady speed (26). My conclusion is that getting the car going is the worst MPG situation so if that is maximized then the MPG is poor. The highway at 67 MPH =2000RPM's and 37.6 on last 100 mile trip. That is outstanding in my world. At 75 it drops to 35-36 best.
    The hybrids get great city MPG with the battery and the Elantra is rated at 29 city. we wanted a more roomy vehicle than a Prius or Elantra and drive a mix of city/highway so it works for us.

    Just drive the car normally and don't pay attention to RPM's and you will get better MPG. RPM's have very little to do with fuel economy.

    Curious comment. I try to purchase a car model that has a lower final drive ratio that results in fewer RPM's at highway speed. The result is lower fuel use in my experience. Sport models use a higher final drive ratio (read Corvettes, Porsche, HP Mustangs and others), to get fastest speeds in shortest times at th expense of fuel mileage. The newer 6 and 8 speed transmissions allow for higher final drive without sacrificing overall performance.

    I think you will find that the trip computer is off by 2mpg (shows 38 -2mpg= 36) Several other Sonata blogs confirm this. I also found that the speedometer is off by 2 miles (verified by using my GPS)speedometer shows 65 actual 63

    The only true way to verify mpg is by dividing gallons purchased into mileage
  • crankeeecrankeee Posts: 298
    I agree with your last comment. I also did the manual calc and came up 2 MPG less. Strange that Hyundai would elect a program that misstated the actual results. Real test of the car will be the long term durability and how well Hyundai stands behind their stated warranty without a lot of nitpicking and fine print rulings. The internet and forums like this will be a true sounding board for both issues.

    I am disgusted with MPG performance. I thought I would average out around 30 mpg. Check this out and (anyone) pls comment.

    I've had the 2011 since May 2011. Over 14,456 miles used 530 gallons, average 27.5 mpg. While not great what concerns me is the variability. I've gotten as much as 34, as little as 19.82. Pure highway I can get it up there. City esp. up hills the mpg drops like a rock. But get this: Hyundai did a recal service on June 29 involving the transmission or some such thing, car popping out of drive while you're driving or something. Before the service I was averaging 29.66. After 26.93. That's my real concern, that Hyundai service did something.

    Anyone know anything?

    We have had the same experience. highway is EPA MPG or even better. The 24 city EPA is hard to mimic with true city stop and go. Add in some freeway and it jumps right back up. I think the EPA test is heavy on California freeway use and light on chicago suburbs stop and go. Most cars struggle to get 20 MPG with true stop and go due to idling time and start from dead stop that kills MPG average. we mayaverage 28 but it requires lots of higway driving which the car prefers. We have no problem with the MPG vs. the EPA estimate. Beautiful car with all the bells and whistles,
    30 MPG city or better in town requirse a low mass roller skate or a car with a $6000 battery that needs replaing ultimately.
    Someday we may enjoy taking ethanol out of the mix to restore the BTU energy of pure gasoline and the resulting 10%+ increase in feul efficiency.
    Ethanol subsidy to farmers and producers allows us to use more gas which
    helps increase the cost of fuel, gas, energy and federal governemnet debt but we prefer the old efficiency of pure carbon fuel - NOT corn!
  • dudleyrdudleyr Posts: 3,469
    Ethanol has about 60% of the energy of gasoline so if the fuel is 10 % ethanol you lose 40% of 10% or about a 4% hit on fuel economy.

    Still significant though.
  • I also am having a problem with my 2012 Sonata Limited gas mileage. I'm getting 19 mpg compared to the 24 mpg on the sticker. That's 20% less. My highway mileage is 30 mpg compared to the 34 mpg on the sticker.
    I also love my Sonata but I am so very disappointed with the gas mileage. Perhaps when the car breaks in further the gas mileage will improve, but I am not counting on that to happen.

    Arrrrgh! I almost wish the EPA would not "advertise" fuel economy listings as posted on all vehicles. Invariably owners, such as yourself believe these numbers to be guaranteed no matter the weather..driving style...traffic conditions...mechanical condition of the vehicle...summer or winter..type of fuel blends etc, etc etc.. I am weary of defending the vehicle as being "to blame" . Once and for all, these numbers are derived in a controlled set of tests performed by the EPA and probably, while able to be met or even exceeded by a certain number of drivers are basically in optimal circumstances. Everything conspires to produce lower actual numbers for most. In short, enjoy the drive and rejoice a car as large,comfortable and quick as the Sonata is can still get economy numbers that were reserved for cars in much smaller size/performance classes not too many years ago. Again, city driving is comprised of stop, then go (slowly) then stop again and idle over and over during which YOU get ZERO (00.00) mpg. Please figure it out before you and others complain about "poor" city mileage it really isn't too hard!!
  • crankeeecrankeee Posts: 298
    Could not agree more with your comments. EPA "ESTIMATE" not guarantee. The new model Sonata offers all the creature comforts, size, safety, GREAT warranty, extreme value for the price paid and if all that is not enough, the Hyundai Assurance plan that was offered up till 1/3/2012 to guarantee trade in value if you maintain the vehicle properly. Other than holding your hand in the dark, I don't know what else they could offer.
  • I have no interest in going back and forth on this mileage issue but suffice it to say I live in San Diego where we have the best weather in the world, I do not have a lead foot and try very hard to maximize my gas mileage. I get 19 mpg in the city (20% less than the sticker) and 30 mpg highway (10% less than the sticker).
    Say what you want, but I think Hyundai knows the mpg's are exaggerated.
  • I've had my 2011 Sonata for a year now and the mileage is definitely nothing to write home about despite the EPA claims. I just say why try to fool us? If they just drop the EPA across the board to REALISTIC expectations then everyone will be happy with their purchase and those who DO get optimal mileage will be thrilled. It's a win-win for everyone.

    I got so fed up with my lackluster mileage that I've taken to EXCLUSIVELY driving with the cruise control on. I use the gas and break in my car only when absolutely necessary. Otherwise if I'm above 25mph, the cruise control is able to take over. Even being extremely conscious about not having a lead foot and coasting whenever possible, I've found that I consistently get much better mileage by using CC than I ever got using the pedals. Never got higher than 21 MPG on a tank of gas using the pedals and now I can get 24-25MPG with primarily city driving using only my thumbs to drive! :)

    the many thousands of people who have purchased this vehicle. with the expectations of decent gas mileage. I feel they have a expectations to receiving gas mileage close to what is listed on the windows. if the gas mileage is not going to be close to what is the manufacturer claims then they should accept the ramifications from the people who purchased the vehicle. although, I can only see for myself. I have tried almost everything to get the listed city gas mileage. when manufacturers use gimmicks to get the public to purchase their products. they often find that the public will retaliate by not purchasing their vehicle, or lo ng terms. the purpose of forums such as this 1 is to ask question s and to be calm informed. I saw your comment about I wish that they would not print the epa listings for this vehicle. and I strongly believe if they had not han days sales would have been reduced by as much as 75 percent. be careful of what you ask for.

    Arrrgh yet again! If anybody is trying to fool anybody blame the EPA they set up the rules, the tests and proceedures and take responsibility for the numbers printed on every manufacturers sticker, not Hyundai they only supply the cars and have no more to say about the outcome than any other manufacturer. If the "numbers" come out looking good (such as they have)Hyundai, as anybody would, (and everybody else DOES) uses those numbers in advertising and why not? Should they say ah hell these numbers are bogus so don't buy our cars??? For those who want stellar city mileage maybe you should be looking at a hybrid, city driving is where they shine the brightest. You know, the right tool for the job. Oh, and I guess San Diego has no traffic?? Right. Finally, read the small print on your says in essence, mileage may VARY. Yeah, it will depending on individual circumstances. It ain't no guarantee folks, not even close. And NO I do not work for Hyundai.
  • dudleyrdudleyr Posts: 3,469
    The epa numbers should be a piece to cake to beat - especially on the highway. They just made the tests harder a couple of years ago and even the old tests were 28% higher than the published numbers so people wouldn't whine.

    Hyundai clearly has issues with meeting the EPA numbers as many are noticing. My Accord on the other hand has averaged nearly 4 mpg over the highway rating for its lifetime (128k miles).

    Hyundai has a lot to offer and Consumer Reports rated the Elantra above the Civic, but despite Elantras higher epa numbers the Civic got 8 mpg more for the CR highway mpg test than the Elantra. The Sonata does not seem to be off by as much, but still seems to have trouble with EPA numbers while other vehicles have fewer problems.

    I don't think Hyundai is cheating on the tests, but they probably are optimizing their cars to do well on the EPA tests, possibly at the expense of real world mpg.

    I rented a 4 cyl Sonota for a week and it got about the same mpg as my Sienna minivan. Disapointing.
    If you still have to the vehicle's monroney label, look below the big bold numbers for the fuel economy in the fine print that says expected range for most drivers. If your car's mpg is in that range than your car is getting the fuel economy it's supposed to get period end of story. Now if it's getting less than that, then you have something to complain about. Please people remember, their are too many factors involved when you consider a vehicle's fuel economy(cargo, occupents, weather, road conditions, etc. etc.)
  • Yes, about the best I can say about the whole "disappointing" fuel economy issue with this car, or many others if you can believe the comments all over the web sites, is this....look at the sticker, test drive the car you may like and its competition, decide then buy. THEN take those economy numbers with a grain of salt. If you are close (and happy) or exceed them (very happy) enjoy your new ride. If they are close and you are not happy consider all the variables listed. If they are far, far off then reconsider the personal conditions that you can control then control them. If you are still far off then maybe you have a problem that requires a dealer look-see. I have seen others post this car or that car (Honda and Toyota come readily to mind) routinely exceed the EPA posted numbers even mini-vans ) and I take these posts with the above mentioned "grain of salt" because while good cars they do not have the patent on super fuel economy while Hyundai is still negotiating the patent rights....

    I have a 2012 GLS w/6 spd manual. Averaging 25 mpg with spirited driving and about 27 conservative. This is in mixed driving, city / highway.
    The MPG gauge is very optimistic showing about 2 mpg more than actual.
    I still trust the pencil and paper method of computing mileage more than any vehicle computer.
    Set the trip odo to 0 when you fill it and do the math at the next fill.
  • I have a 2012 Hyundai Sonata Limited (non-turbo). I had a 2011 Sonata Limited and made the "mistake" of trading it in for a 2012 Kia Optima. Obviously I did not like the Optima, as I am right back to the Sonata.

    Anyway.....I live in Chicago and we definitely have crappy weather, and deal with the "winter blend" of gas more months of the year than the "normal/summer" blend of gas. I have had the car for almost 2 weeks now. It came with a full tank of gas in it, and I finally filled up yesterday. I do about a 50/50 mix between "highway" (although it is not true open road highway driving, as it is Chicago, and it is more stop and go highway driving, but not as bad as stop and go in the city of course) and "city" driving. I calculated my MPG manually when I flled up yesterday, and I got 27MPG - and I never use cruise control.

    When I had my 2011, it was in the summer, so the "non winter blend" gas and I got around an average of about 29MPG with the same driving style, travels, etc. that I have now. The winter blend will account for lower milage due to the additives that are put in the gas.

    But, needless to say, I am thrilled with my Sonata and the gas mileage it delivers (not even using curise control as I said) and I am not a "slow/speed limit" driver either.
  • I am almost up to 123,000 miles on my 2009 GLS 4 cyl. automatic. My lifetime average is is 35.09 mpg. The lifetime covers 121.5k miles. I missed the first fill-up amount and then two other fill-ups at some point.

    I try to maximize my fuel efficiency and have a job that puts me on the road a lot and gives the opportunity to do so. I would say that my driving consists of a good 90-95+% highway/interstate driven at 60 mph with cruise control and easy hills. My worst tank was 30.4 and my best was 39.1.

    Most of my driving consists of a rural highway ride to the interstate (eight miles at 45-55 mph), and then another 50+ miles to a bigger city where the last mile or two will be city traffic. I notice that the longer my highway stretches are, if I'm going 100+ miles out to a destination, then my mpg gets better. Conversely, the more city driving I have to do the worse it gets.

    Speed can play heck with the mpg, too. While I mainly try to do 60 most of the time, there are plenty of times where I have to hoof it up to 75+ for the whole time and my tank mpg will get down to 32-33 or so.

    Graphing the lifetime mpg shows a seasonal variation (thank you cold weather and winter mix). Best mpg is the warmer months with minimal AC use. I usually won't get over 36 mpg on a tank from october to april. I start hitting 36+ in may, but that's usually on the super highway heavy jaunts.

    I have to say I am impressed. I am considering getting a new GLS at the end of the year. I expect to drive it the same way and am curious to see if it will do better. It should, given the six-speed transmission and GDI.
  • We owned a Fit for about a year. The wife mainly drove it. I stuck to my Sonata. However, I did drive it enough for the first fill-up, trying to maximize mpg. I managed to get 43.1! For the year my wife drove it, she usually would get the high 20's. She mainly drove it for work, which is 3 miles round-trip.

    You are correct. There is no comparison. The Fit is a light-weight thing. I think I could have made it a highway MPG monster, but the wife just couldn't stand it and traded it in for a 2011 Sonata Limited. She LOVES the Sonata Limited. I haven't been able to put it through some max mpg paces, though. I just keep piling the miles on my 2009 GLS.
