Midsize Sedans 2.0

    It doesn't measure a 25% change. It only reports if it's 25% too low. Did you read the link I provided from Hyundai? It spells it out very clearly. It also explains that the display for a low tire and the display for a sensor problem are the same except the sensor problem flashes for the first 60 seconds. If your tires were not 25% too low then it was a temporary sensor fault. There is no other logical explanation.

    "No, it's no big deal to me"

    Sure seems to be. My comment was directed at benjaminh, not you. I think it was pretty obvious in my post that I mistakenly replied to your post. Didn't realize that posts were exclusively between two people and not for others to comment on. I'll have to remember that.

    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.

    Of course you do know that the air is 80% nitrogen? So the "pure nitrogen" filled tires are only different by that other 20%.

    Aircraft use nitrogen because their braking generates high heat, and oxygen from air supports flame in the presence of petrochemicals, which are right nearby on aircraft. If/when aircraft tires blow out, you don't want flame-supporting gasses expelled.

    I meant no insult and I'm sorry if you took it that way. I based my comment on two things.
    1. Your comment that the attributes of nitrogen filled tires is nothing but "hot air".
    2. Your comment about the retread tires being the only use for it.

    The hot air term insinuates to me that anyone making a positive comment about nitrogen filled tires is full of hot air. The retread tires being the only use for nitrogen comment and the non-mention of nitrogen being used in race car tires and airplanes indicated a less than full grasp of the application of nitrogen in tires in general. Those two applications where it is crucial that air pressure be maintained or disaster can result. I guess I shouldn't have used the term "make fun of" but that is what it appeared to me. Just like what I wrote appeared to be an insult which was meant more as sarcasm in general versus a direct insult.

    Yes, that is pretty basic. It's the other 20% I was referring to. There is a difference to how the two mixtures, air vs. pure nitrogen, react to heat, cold, moisture and the molecule size providing a small difference in leakage both at the rim and through the actual sidewalls.

    I'm just relating what my experience has been with 4 different vehicles and three different brands of tires versus the experience I've had over 40 years of driving and probably over 100 sets of tires purchased and maintained. I have no vested interest in the "nitrogen industry" and as I said earlier, was pretty ambivalent towards it until I got it for free from Costco about 6 years ago. I'm sold on it now because I just don't have to add air to my vehicles anywhere close to what I ALWAYS had to before.

    Just noticed this and thought I would throw it out for discussion.

    The new Corolla has increased interior space from 91 ft3 to 98 ft3 and rear legroom has increased by 5 (yes five) inches. This is something that I have always wanted car makers to do - just increase the rear legroom by stretching that area. It seems they always manage to make the car 6 inches longer and add .8 inches or rear legroom (or whatever the numbers are). Vw kind of started this trend with the Jetta (and to some degree the Passat), however Toyota has taken it to a new level with even more interior ft3 and legroom.

    So the question is - where would a car like this sit size wise. If a compact has more space for passengers than a mid size is it still a compact? The Corolla is now officially a midsized car according to the EPA. Will it really be considered one by consumers as it has the same space as a 2013 Mazda 6. Will people be criticized for bringing it up here?

    Hypothetical on the Nitrogen.

    Nitrogen molecules are larger, so if air leaks out of your tires it is the oxygen leaking out as it fits through smaller holes.

    Eventually you only have nitrogen in your tires. :D

    Vw kind of started this trend with the Jetta...

    Yes, "kind of" is right. Actually, in the compact class Hyundai started this trend with the 2001 Elantra, introduced here in the fall of 2000. I believe it was the first compact car to offer mid-sized interior room, including a very roomy back seat. That was one of the main reasons I bought the car 13 years ago. The Jetta of that time had a pretty cramped rear seat.

    Now, only 13 years later :) Toyota has finally built a Corolla with a rear seat suitable for most adults. Nice to see, but a little late in the game compared to Hyundai, Kia, Nissan, VW and maybe others that offered compact cars with mid-sized interiors well before Toyota did it with the 2014 Corolla.

    And, btw... we've had this discussion here before, i.e. compact cars with mid-sized interiors and where do they fit. ;)

    You know, I'm not a mind reader and didn't know you really meant your post to be directed at benjaminh instead of me until you told me. Thanks for the clarification.

    And of course I don't think posts are exclusively for two people. But it helps avoid misunderstandings when you reply to the message you intended to reply to. ;)
  • m6userm6user Posts: 2,952
    This is now the third time I said I made a mistake. Of course it would be clearer if I hadn't made that mistake. Now, shall we drive it into the ground or what? I'm sorry I replied to your post and upset you. Move on.l

    Elantra achieves midsize status with a larger trunk since the EPA adds trunk space to interior space for classification. The Corolla has the most interior room beating the Elantra by 2 ft3.

    I was aware of the Elantra, but sitting in one did not seem that large. Kind of like the Chevy Cruze - larger than than many compacts in ft3, but still a very crowded rear seat.

    The US corolla gets a solid rear axle and the euro version gets an independent rear suspension. Seems the US buyers could care less about handling. They want the cheapest Corolla possible and would never notice the difference anyway. That's according to Toyota. I guess very few buy a Corolla here expecting any "ultimate driving experience." If you know your market, you know your market.
  • backybacky Twin CitiesPosts: 18,682
    That really wasn't the point, but... whatever.

    If you think the Cruze and Elantra have comparable rear seat room, I don't think you've spent much time back there in those cars.

    But back to the original topic... with as much interior room as compacts like the Corolla, Sentra, and Jetta (and I'd say also the Elantra and Forte but you might disagree so forget I mentioned it) have, it's less likely someone would need to buy a mid-sized car for interior room. More likely they want the added power and (in some cases) features a mid-sizer offers.

    Don't forget overall ride quality. Heft and wheelbase add a lot to the overall ride that many people look for in a midsize car. I like the new Mazda3 as it has almost the same amount of interior space as our 2007 Mazda6. But, due to it's weight and wheelbase and sport tuned suspension it is too jittery for me. I'm really looking forward to the 2015 Mazda6 for three reasons. 1) Some bugs of the new model should be worked out. 2) The diesel should be intergrated but I'm not sure if that would be the one I want though. 3) I'm hoping they drastically improve the infotainment center with a larger screen and better NAV.

    However, recently my wife has been saying that her next car needs to be a lot quieter than the Mazda6 she's driving. That may lead us into another direction altogether. That would be too bad as I really love the new Mazda6. Another possibility is that a lot of reviewers rave about the Mazda6 in just about every area except the infotainment and the road noise. If Mazda improves on both of those areas a little the 6 could be still be a player.

    Heading out to Indiana tomorrow from CT.
    Filled up the Fusion with premium gas, although it wasn't quite empty.
    The first outbound leg of the trip, taken a couple times already, always returns the worst fuel mileage, as it is mostly climbing.
    Hoping to make it to Ohio on one tank.
    Reactivated my Sat radio, so we can listen to some sports on the way home.

    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.

    No review would be written like that.

    It reads less like brochure copy and more like a press release. The old "features and benefits" section. All fluff.

    Frankly, if he isn't on Hyundai's payroll, he ought to be.

    I'll be test driving an Optima 2014 SX Turbo w tech and leather this weekend. Anyone have any advice or things to look for? On the surface, I'm expecting it to drive like a Hyundai with a nicer looking interior.

    Only advice is get pre approved for financing just in case.
