    We actually did hit 40 once on a hwy trip with the CVT Accord...

    And I hit 42 mpg once on a highway trip in my Sonata. ;)

    The 2013 Sonata does exhibit better FE than the 2007 Sonata I4 we had before that, despite a big boost in hp in the newer car. I always got over the EPA 30 mpg highway number on the 2007 car, typically 33-34 mpg at 65-70 mph. So the 2013 does well in comparison. And is pretty close to the latest designs despite being a 4-year-old model.

    I'm amazed at how close in highway FE my Sonata can come to my 2013 Rio, despite the Sonata having 60 more horses and a lot more weight. The Rio does much better around town than the Sonata, however. Both have the 6AT.

    lol! I've never gotten more than 40, and so you've got me beat.

    But a guy over at driveaccord.net had a 600+ mile tank and got 43.1 mpg....He even has a pic of it:

    I agree. If I was Mr. Hyundai, that is exactly what I would do. I knew something was up when I saw some dyno numbers on my car. It was making 139 hp at the wheels. The parasitic losses are usually 30% to 35%. At 35%, my car would then put out 187 HP. So, I think 192 is a realistic number considering that peak horsepower may only be measured at 5900 to 5950 rpm, with sustained horsepower more like 185.

    35% parasitic losses is surprisingly accurate with an automatic tranny, which is why the move to CVT's.

    Funny, you say "we" got X mpg and backy says "I" got X mpg. Maybe you should only measure your MPG when you are by yourself and not hauling the whole family and gear. Add 500 lbs or more and any car will get less MPG. Driving by yourself on a lengthy highway trip could put you at 40+ mpg or more it sounds like. Elevation and temp plays some role too not a whole lot unless you're in the mountains.
  • akirbyakirby Posts: 7,747
    The Hyundai system does not check for variance between tires - it uses a stem mounted sensor. It does not check for overinflation - only underinflation by 25%. If your system does not indicate which tire is low then it will also illuminate the TPMS tire symbol to indicate both a low pressure AND a sensor fault. For a sensor fault it flashes the light 60 seconds first. It could have been easily mistaken for a low tire.

    This is true for 2010+ models - I suppose it's possible the other system was used on earlier models.

    Of course YMMV on FE. But why address this to me when benjaminh started the whole thread with "I got 40 mpg once on my Accord." ? Also we were clear that these were examples, not a general rule with these cars. Just because I can hit 42 mpg once on my Sonata doesn't mean everyone will get that, once or ever.

    FYI, I’m getting this info from several sites; Google can be helpful.
    The display on Hyundai’s telematics system, Assurance Connected Care, now has a simplified user interface, better navigation screens, and probably the best voice recognition found in any vehicle.
    The system is also reputedly more intuitive for frequently used tasks.
    The voice recognition software understands street addresses and cities all in one sentence while simple pop-up messages now appear to help pair a cell phone; previously pairing with most Hyundais could be maddening.
    The route screen also displays speed limits and details the next three maneuvers and one or two button pushes now complete most functions unlike the complex Ford system.

    The nav system on the Mazda6 has been universally panned in every review but it does recognize street addresses and cities in one sentence and does display speed limits so I guess I shouldn't complain.
  • jayriderjayrider Posts: 3,455
    Your glowing prose regarding Hyundai is always so positive and never addresses any areas where it is bettered by the competition. I find your writing style to be definitive and assuring amongst all the harsh rhetoric that finds its way to many postings. The least I can do is take both my cars to the local dealer and trade them in for a pair of new Sonatas. I suggest the rest of you misinformed doubters do the same.
  • explorerx4explorerx4 Central CTPosts: 9,972
    You are so lucky to have 2 cars to trade in. I only have one 2013 Fusion Titanium and I'm conflicted about trading it in for an Optima or a Sonata. ;)

    > I replaced the regular air with nitrogen and that seemed to fix it.

    I doubt that was the fix. The atmosphere is 80% N2 with a mixture of other gases which have about the same thermal coefficient of expansion. The idea of N2 being useful for auto tires rather than truck carcasses which are retreaded over and over has been like politics--lots of hot air.
  • kyrptokyrpto Posts: 216
    Probably should wait a year to trade and see the next gen as the Sonata is due for a new body for 2015.

    But then you can trade them in for the all-new, vastly improved, undoubtedly class-leading 2015 model!

    With 50 improvements for model year 2014, I doubt there will be much more than a refresh of the exterior in '15. Not much left to improve.

    But Hyundai could maybe offer self-parking or accident avoidance.
    I understand the Subaru collision deflection system currently works the best.

    The new Hyundai app for Blue Link for 2014 will allow subscribers to remotely access various optional features and services through compatible mobile devices; my wife uses both her iPad and Galaxy S IV to control the 2013 version.

    It has been significantly enhanced from the previous version and boasts a new user experience, faster navigation and innovative new features:

    Stolen Vehicle Recovery
    Stolen Vehicle Slowdown
    Vehicle Immobilization
    Alarm Notification
    Panic Notification
    Valet Alert
    Geo-Fence
    Speed Alert
    Curfew Alert

    Wonder if this can be improved for 2015?

    It was an AWD. I wonder if that's really worth it though. I just noticed kia optima came out w their 2014s. That interior looks nice. Seems very ergonomic. And I've heard the give out great incentives. I've never ever thought of owning a kia though.

    But so is the Sonata.
    Since the launch of the current generation in 2010 as a 2011 model, Sonata has undergone significant changes to reduce cabin noise.
    Both our 2011 and 2013 hybrids were very quiet, more so than our ’07 Camry, ’10 Venza, or any other vehicle we’ve owned in the past decade
    So several new engineering changes will be noticed immediately by Sonata drivers and passengers:
    New 17- and 18-inch wheels to reduce road noise inside the cabin
    Improved carpet insulating properties to block road and engine noise
    Additional foam in the A and B pillar to reduce road noise
    Additional dynamic damper to improve road noise

    You have to understand that I had 600 pounds of kids and luggage jammed in the car. This, plus sustained 80 mph speeds should have had all 4 tires reading high, plus the 3 psi I over-inflated before the trip (to increase F/E....I saw on Myth-busters that it actually works).

    So, I think the tire was low by 3 psi, but not below the recommended pressure so I was irritated I had to stop for basically nothing. I would bet the tire leaks a bit at speed under those conditions, but who knows for sure.

    My 2001 Windstar had its TPMS light on the entire time we owned it....which defeats the whole purpose of having it. This is why I was so irritated when it came on in the Optima for no real reason as well.

    "Building on their well deserved reputation as a design leader, Hyundai designers and engineers have upgraded nearly every system in the 2014 Sonata".

    Dude, come on man. What are your PERSONAL experiences with your car?

  • akirbyakirby Posts: 7,747
    What year is your Sonata? Unless yours has a different system than the 2010+ Sonatas it does not measure overinflation or the difference between tires - it only measures a 25% low condition. However, if there is a tpms fault (sensor problem) it will also illuminate the tpms light just as if there was a low tire. You may have had a temporary sensor problem.

    "But why address this to me when benjaminh started the whole thread with "I got 40 mpg once on my Accord.""

    Because I mistakenly hit reply to your post instead of benjaminh's post. Sorry, but I wouldn't have referred to you in the third person if I meant to reply directly to you. Is it a big deal? My point was that it appeared that you were trying to make a point that your Sonata got just as good of mpg in "real world" as the Accord. Didn't we just go through a bout with Hyundai and their "real world" mpg numbers being a little off? I probably got 40mpg with my 6cyl Acura for a short stretch too but it's hardly worth noting. I've found that if a car is rated 2 mpg higher that, on average, that car will probably get 2 mpg better in real world driving by the same driver and circumstances.

    I also was making the point that in many posts you say "I" achieved a certain MPG and benjaminh made it a point that he had a car full of people and luggage. So, I was commenting simply on the fact that comparing road trip avg mpg of car loaded to a single driver in a car was really not apples to apples and could account for a couple of mpg's possibly.
  • m6userm6user Posts: 3,048
    Yeah, I know Google can be helpful. If we want to see reprints of all advertising and/or glowing comments in auto reviews we can use google too. We don't need you to go out to the internet and try to find every single thing nice said about the Sonata and then copy and pasting it in here. Proper etiquette has one cite a source and then make it clear with quotation marks that it is not your original thought but copied from somewhere. Secondly, it is much better to just post a few words from the quote and then provide a link.

    Frankly, your posts are like a broken record and they are just another copy from some auto review where they said something nice about the Sonata or some of it actually looks like it's copied right out of a Hyundai brochure. Really, really boring.

    I'm sure this is from someone that has never really tried nitro in their tires but is quick to make fun of others that do. I never had one opinion or another about nitrogen in my tires until I bought a set of tires at Costco and they put it in for free.

    A little history, I am one of those guys that really likes to have the correct pressure in my tires. I've have always had three vehicles for the past twenty years and kept a small DC air compressor in the trunk of each vehicle just to have it handy for emergencies and to keep my tires topped off. I was using them quite often. Then I got the tires from Costco and I noticed that I hardly ever had to add air to the airs. And I mean for very long periods of time....like years! I figured at first that Costco just did an excellent job of installing the tires and the tires themselves, Michelin, really did the job. Then I got another set of tires from Cosco for my truck, BF Goodrich. Again, I virtually never had to add any air to the tires. I found this to be rather astounding. Then my wife's car needed tires and we replaced the original Michelins with more Michelins from Costco. Same story. Two of the cars are garaged and the truck sits out all the time and doesn't get driven regularly. I was always putting air in those tires. Now, nothing except maybe once a year swinging by Costco and getting the tires rotated and i assume they check the air in them but I'm not sure. I check the air about every 3 months in the truck and about every 6 wks in the cars. It's pretty unbelievable to me that I never need air in these tires.

    Race cars and airplanes use pure nitro in their tires so it's not just recapped trucks and I'm not even sure that is true on the recaps. Nitrogen has larger molecules which don't seep out as easily as oxygen and it also less affected by heat. I'm on fourth vehicle now that has nitrogen in the tires. This last one is an Acura and it just went in for it's first service at the one year mark and to date no air has been added to those tires and they are still the same pressure as when we bought the vehicle.

    So, maybe it's all psychological but I've pretty much retired my little air compressors and from personal experience with four vehicles am pretty happy with the little green caps. I wouldn't pay a huge amount for the nitro but for a few bucks it's worth it to me. YMMV(if you've even tried it).

    No, it's no big deal to me but you seem to want to make it one.

    I'm not sure what the problem is in two mid-sized car owners chatting about their FE results here. They shouldn't be taken as gospel or a guarantee for anyone else with the same cars. The comment was made that the Sonata might catch up to newer designs in FE with its next redesign. I was providing my experience with the 2013 Sonata to demonstrate that at highway speeds mentioned by benjaminh with his Accord, the current Sonata is already very capable of similar FE results to new designs like the Accord.

    Oh yeah... YMMV.
  • kyrptokyrpto Posts: 216
    The many improvements made for model year 2014 are exciting to me as an owner.
    Not cutting-and-pasting as you incorrectly allege but reading and condensing info from Hyundai.
    Not reprints or copied comments from ‘14 Sonata reviews; car is too new for those.

    I am also including many personal observations such as:
    “Very good analysis Dudley.”
    “Consumers aren’t buying boatloads of Sonatas because they have the most horsepower; the spacious interior sells more units.”
    “A major selling point for mid-sized sedan buyers are the, if you will, ‘infotainment’ systems most vehicles are built around.”
    and the examples could go on-and-on.

    Sometimes I use bullet points to cite the many, many improvements Hyundai has made for 2014; would be dumb to take up more space arranging that information into a paragraph and a list is easier to read.

    Guess its not as interesting to non-Hyundai folk but it is surely as compelling as the lengthy debate going on here on TPMS.
    Personally for those trying to stretch MPG the 4 corner, exact pressure readings from the new Hyundai TPMS is an invaluable tool.
    So are the now common instant-MPG-readouts.
  • jayriderjayrider Posts: 3,455
    The differences in MPG for comparable cars won't make anyone rich or anyone poor. They all do pretty well.
  • cskicski West Springfield, VAPosts: 1,341
    My Sonoptima is a 2012, and you are right. It only measures a 25% difference in pressure on any given tire. I never said that it measured the difference between the 4 tires, only a change in one.

    Look, if the system came on all the time I would have it checked out. It works fine. Only on the trip did it illuminate. I have had it for 2 full years and 24,000 miles. I have brand new tires and I know for sure there is nothing wrong with them. The car was heavily loaded for the very first time, and the tires were consistently hot for the very first time. I will ask about it next time I have a (free) oil change....which I have for life. (I really like free).

    My local Shell has nitrogen fill available for free. I have been thinking about doing it. Thanks for info about your experience with not having to add or correct pressures.

    Maybe I will go over and get it done tomorrow.

    This is the kind of advice people can actually use. I have a compressor pack in the trunk as well....but it is not a real bonus as my car has no spare. More of an emergency item along with a fancy can of Kia-brand fix-a-flat, which cost $25 to replace at the dealer. I used it once when i had a nail, and it ruined the tire, even though I followed the instructions to a "t".
