    Hello,

    Its been a while since I posted here. I used to drive a 2007 HCH which was a good daily driver, yielding 52-62 mpg tanks depending on the weather in the Midwest US.

    I purchased a 2015 Sonata Eco in February, in part due to the strong reviews/trip reports posted here.

    I have put on over 5k miles since then and my daily (75 mile RT) commute has come up from ~37mpg to ~45mpg as things have warmed up. I have not altered the car in any way, tires at 38 psi and I simply drive the 55-65 mph speed limits and minimize the stoplights I could hit.

    The 7 speed DCT is interesting - its like an ultra quick shift robo MT. It will pull at ~1350 rpms in 5th-7th at 28, 38 and 48 mph respectively.

    So far, its a surprisingly efficient full size sedan. Let me know if you have any questions.

    Thanks for the info. Do you use CC, AC, what is the rpm @60mph and are you on flat or rolling hill highways? It looks like Hyundai has a real winner with this one.

    I have one really flat route option that I can use CC 80% of the time. I have another shorter, hillier route where I use both CC and the Shiftronic part of the time.

    At 60mph, 7th gear turns about 1800 RPM.

    I limit AC use but I'm messing with ~85F AC on recirc mode these days. Keeps me comfy when its hot and humid outside.

    Hi SpartyBrutus:

    That 7-speed DCT was one of my favorite features in the Sonata ECO. Hope they place that same transmission in the rest of the lineup.

    Did you choose the Tech Pkg or run it bare. And what kind of deal did you pick it up for?

    TIA

    I got the Tech package.

    Nav, blindspot warning and rear backup cam all work well and I use them more than I thought I would. There are now way too many ways to listen to music including 106GB on a USB..

    $24k out the door.

    My wife purchased a 2015 Sonata Sport. It really is a nice car. Have you had any issues with the gas tank filling to top or does it short fill you and tell you have to fill when when you still have 4 gals sitting your tank?

    My wife is going in for some coating that came with the car and will have ours looked at as she is only be able to fill 13+ gals in the tank instead of 16 when it says to fill up. She is getting 33-35 MPG on her tanks so far as she travels down the highway for work.

    I can get some good numbers using the shiftronic and shifting to neutral around town.

    I have had the same issue with the Sonata "hiding" about 2.5 gal of the 18.5 gal capacity.

    In my case I think there is ~1 gal in reserve below E and ~1.5 gal above 1st click at top off. I usually have to trickle in fuel after the auto shutoff. The Hyundai owners forum has a thread about this.

    Hope you and your Wife enjoy the Sonata!

    I have seen the thread and have provided the information to my wife and is supposed to be taking the car in to be looked at this week. I'll try and remember to let you what they say.

    I have told her not to accept the standard babble from them that this is normal. It is not, she agrees and will keep them working on it until it is fixed to HER satisfaction.

    Yep, leaving 80-100miles of range on the table due to inaccessible fuel tank capacity bugs me too.

    I did seem to trickle in ~1.3gal in after the first click last fill up. That's why I think there's some space above "F".

    Good luck.

    You probably try to Top-Off keeping the filler on the hole. This is how Wayne Gerdes does it by keeping the filler outside the hole and very slowly filling until he sees the fuel. He was able to get an extra 4 gallons in my car after the first click but it took him 10-15 minutes extra.

    Thanks for the fill tip - Ill try that next fill!

    At 19k miles with no issues. 40.4mpg lifetime with only a bit of hypermiling techniques used.

    Like the 7 sp DCT tranny but I still miss manuals on my prior Sonata, Accords.

    Meh, I'd hate to be waiting next-in-line while you shoehorn tablespoons of gas in. Your first hard right turn may jettison it, into the environment, and/or your fuel evaporation components. What is the point of this again?

    Hi Mendel:

    I use it for calibration. Without that, all efficiency measures by every reviewer out there is wishful thinking. You also do not jettison gas but it can harm evap components over time.

    Hi Jeff:

    It is the fastest shifting of all the DCTs and non-DCTs in non-high performance cars I have ever driven. Torque holes have been reduced from earlier Hyundai ATs as well. Its key is the efficiency. It is a manual for all intents and purposes with no energy robbing Torque converter getting in the way.

    Longevity, I do not know how it will stand up.

    As Wayne pointed out, its really a quick shifting "robo" manual tranny. It can stay in "N" for a bit too long when starting from 0 mph - then it catches, just like letting out a manual clutch. This may be unnerving to those used to ATs. I think I'm due for a DCT flush/fill sometime by 30k miles but I have seen no issues through 19k miles.

    Additionally, I like that its "robo" shift points in normal or eco modes at ~30, 38 and 48mph kick into 5,6 and 7th gears and drop RPMs down to <1400. It does not lug at these RPMs and seems to deliver good FE.

    How much does the flush/fill cost?
