The Hyundai Sonata Hybrid is the best package of attractive styling, smooth handling, excellent mileage and comfort among hybrid sedans in the US. I found with slight care its easy to get over 40 mpg on the highway and overall 38+mpg. Features that reduce the mpg are using heated seats and interior heater in the winter or full AC in the summer. However, using the "econ" feature with the heating/cooling one easily achieves 38 mpg overall or better. The jitteriness at low speeds was resolved with the first service when the computer system was upgraded to remove some of the hesitency between use of EV and gas engine modes. Update is free and resolves issues raised in some initial reviews.
I purchased my 2012 Sonata Hybrid new from the dealership. This was my first "fancy" car, as I had always gone either base model or used in the past due to financial difficulty, but I was finally in a position to spoil myself a bit, and was able to justify my expense in the fuel savings, or so I though... Highway miles truly are 38-40, and I can even get that if "cruising", but only if the weather is nice, and traffic is light. Here in the Midwest we get temperature extremes which effect the fuel economy a great deal, and stop and go city driving averages 32 mpg which is no where near what they had advertised. My friends all say I drive like an old man too, so I know it's not just me...
Leased this car on the premise of great features together with great MPG. Traded in my old gas-guzzling SUV for "great" gas mileage. First tank lasted 550 miles, I was elated. After that my MPG has been taking a dump. I was quite surprised because my driving style is very cautious, even boring. My lowest whole tank average gas mileage at fill up was 16mpg. Absolutely pathetic, I should have gotten a truck. Got sold on comfy seats and sticker MPG. I expected the mileage to be less than sticker but not like this. If you live anywhere that gets cold, and you don't do lots of long distance driving, avoid this vehicle like the plague. I am counting the days until it disappears from my life.
Bottom line over half my car payment is going to be made by the money I am saving on gasoline. I have gone from driving a truck that gets 15mpg on its best day to a car that I can see is getting 38mpg in the city and over 40mpg on my 25mile trip home from work. I am extremely pleased with the handling. It has a smooth transition from electric to gas engine. Most of the time I don't even know it happened. I did go with the leather package and I am extremely pleased with the interior design. Plenty of room, and stylish. The exterior design is great as well with a cool set of lights. I would love to have a different set of wheels but that is avail. for a little more money. Very satisfied!
Took delivery of my new Sonata Hybrid on July 18. Very happy with car so far. Five tankfuls of fuel have given me an average over 39 MPG...if the tank is mostly highway driving I get average over 40, if mostly city/errands and such about 36. No problem with switching between electric and gas engine. I think there may be a learning curve to learning to drive the car for the most economy as sometimes the gas engine will come in pretty strongly, especially in hilly terrain. Car is very comfortable for long drives, my bulged discs don't even know! (to be fair, my '07 Sonata was the same way). The handling may not be quite as good as my last Sonata, but this one also feels much bigger.
