You are in the Hyundai Sonata
What is this discussion about?
Hyundai Sonata, Fuel Efficiency (MPG)

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!

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!!

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!
