Funny thing about gas mileage ...

You can take the exact same car and run it through several different drivers and get different fuel economy.
A coworker complained since day one about the fuel economy of her Elantra. It is mecanically identical to mine. I get 32-34 on the highway, she gets 25-27. Combined driving I consistently get 30, she gets 22.
I only had to ride with her one time to understand the problem. Gas, brake, gas, brake, gas, brake ...

jlflemmons got it right in post 89. I live in a cold climate have at most a 5 minute commute to work, all city driving so my mileage is pretty bad.
My buddy bought an 08 tucson fwd (see my specs in post 86), but he drives all highway to work, even though he's still in the break-in period not even 5000miles yet, he gets closer to 18-20 mpg. I saw a huge jump after break-in so he may get even better mileage this time next year.
I agree 15 mpg is pretty bad and if i had known thats what i would be looking at for mileage for 6 months of the year i would have bought something different. I've also had my fair share of problems with a 1 year old car which doesn't help.

I've got 11,500 miles on my loaded '06 Limited V6. I drive in urban traffic conditions 22 miles one-way to work and some limited highway weekend miles. My avg is now 19.8. Sure, I could be getting in the high 20's or even 30's BUT with a MUCH lighter vehicle that wouldn't have all the features and space of the Tucson and I really wanted 4WD. My vehicle weighs about 3,500 pounds and there's just NO WAY you can pull that much weight and do better mpg-wise.
As far as the above posting about re-routing the cold-air intake, sounds good but you're really screwing with the computer, messing up your emissions and will probably burn your valves. I'd stick with stock and not risk voiding my warranty.

Here is another perspective so don't trade in your Tucson yet. Let say you are getting 17mpg and drive 10,000 miles/year you will spend $1764/year on gas at $3/gallon. If you purchase a similar SUV, say the Honda CRV or Toyota RAV4 you might get 2 to 4 mpg better mileage (RAV4 is smaller, CRV has a 4 cylinder). So, let say you can get 4mpg better at 21mpg and 10,000 miles/year you will spend $1428/year on gas for a savings of $336/year. The RAV4 or CRV will cost you at least $3000 or more to purchase over the Tucson so it will take 9 years before you break even on the gas savings. If you put that $3000 in a simple investment that earned 8% a year in interrest, the earnings over 9 years would pay for the gas milage differance of 4 mpg and you would still have the $3000 left!
Toyota is a good car, but in my mind, inferior design because you have a stupid tire hanging off the back, side opening hatch and it is smaller. I can't say anything bad about the Honda CRV except I think it is a bit ugly and they think a lot of it and charge accordingly. It is also only a 4 cylinder. Both these autos have half the warrantee and you can't beat the fold flat seats in the Tucson or the nice storage under the rear compartment lid, or the full size spare under that, or the great mp3 player, all the features and built in options and nice up-right seating position. I think that is why many of us purchased the Tucson, good value and a very comfortable and safe vehicle.

I can understand your concern about modifying the cars intake for better performance – my wife doesn't like it either. But, I am an engineer and I like to tinker. The safest and least disruptive modification you can do to a modern gas engine is to improve its air intake. It does not have any negative effect on the computer or emissions because the computer senses the air flow increase and adjusts the fuel/air mixer and timing accordingly. Every auto manual warns you about diminishing performance with plugged air filters, I'm simply going the other way. All the automotive performance web sites sell high performance filters and assemblies from makers like K&N. Here is a link to WIKIPEDIA that tells you all about hood scoops and why they improve performance: http://en.wikipedia.org/wiki/Hood_scoop

I really hope you will post your results if you modify your vehicle. We may all want instructions!
I am getting 23-24 mpg on mostly highway miles. At the price of gas, we can all use improved performance.

I have a 2007 Tuscon with the 4 cylinder engine. My commute to work is about 3.5 miles. When I just go to work and do not do any highway driving, I get 17-19 mpg. I had a 97 crv that got 23-25 for the same distance, I have take a 125 mile trip and I got 21.7 on the hwy with the Tuscon. I am heading to Maryland next week and will drive about 700 miles. I will repost my results. Other than the gas mileage, I really do like this car.

I purchased a new 07 Tucson in June 07. I normally avg about 335 miles to a tank full of gas. My avg mpg on the highway has topped at about 22 mpg on the highway. I have been so impressed with the vehicle (the way it drives, the comfort) but have seriously considered trading or selling it due to the poor gas mileage. I have the 4 cylinder model and it is depressing. This thing reminds me of huge Olds I drove back in the late 70's.....it never could make it past a gas station without needing a fill-up.
LOOK very closely if its comfort you want.....if not, pass on the Tucson....it wont deliver the MPG unless you have deep pockets ! It LOVES gas !!

Well i'm in the same boat as tusconstar above, but i've had my tucson for over a year. I get worse gas mileage (v6, awd, cold climate) but i felt it was ok since the truck is really quite comfortable and nice to drive. But things have started going wrong with my 1 year old tucson and the dealership is a royal pain in the butt to deal with. So this weekend i started shopping around, unfortunately it looks like after a year of driving the vehicle has depreciated by $10,000.
I'm looking at the 2009 toyota matrix, hopefully it will be greener pastures.

I traded in my 2006 tucson for the mileage issue and gas prices these days. I just made a trip of over 500 miles and averaged 36 mpg on the trip and got 40.26mpg in a 285 mile leg of the trip. I really liked my tucson but I am glad I got the 2007 elantra for the mileage that im getting.
