I filled up at a station on the FL tpke. and got right on the highway.
Set cruise control to around 63-64mph, and watched my fuel consumption skyrocket.
This test was only perhaps 10 miles, but I managed to see 44.9 on my computer.

Has anyone gotten higher than this?
I probably could have done a bit better had I set the cruise at 60.

Haven't come that close myself. The highest I got was 40.4 miles per gallon on a short loop through a flat level of road of about 5 miles after refueling. It was about 2 a.m. on a stretch of 4 lane road that's not really busy during the day and even deader at night..so much so that I can pretty much predict when the stop lights will change since they go on a "cycle" at night when the road is dead. Speed limit is 45 - 55 mph in the area and I was probably doing around 50 with my foot steady on the acceleration without using cruise control. By the time I got home that night it had dropped down to 34.3 mpg but I was still impressed.

The car is very impressive when it comes to fuel efficiency, I'm not so sure why so many people are wanting to jump on the hybrid bandwagon. It really comes down to how your drive as opposed to what you drive but I digress. I think anyone who is considering the Sonata hybrid because of it's fuel efficiency should really do themselves a favor and take both cars out on a loop or extended test run before choosing one over the other. They may actually find that for their needs the more fuel efficient car may just be the normal one that only gets a mere 35 mpg rating highway.

Hitting 40+ mpg has got to be a boring drive.

Plus, at least by me, people would be swerving to get around you. :whistling:

I guess if it's a long road trip I could understand.

I think that 50 - 60 mph is the sweet spot for best gas mileage.
On my last trip , I drove about 70 miles on a 55 mph freeway doing about 61 mph.
My average mpg rose up to 36.9 .
As soon as I hit a section of the freeway that was posted at 70mph , and drove 76mph , the mileage started to drop all the way down to 34.7.
My wifes daily 12 mile drive to work ,with just on stop , nets her 29.1 mpg.
Also ,according to my GPS , the Sonata's speedometer is about 1 - 2 mph faster which will effect your actual mpg.

When I first bought the car and got on the highway, I was getting 41.2 for about 2 miles then it dropped down. In mostly city driving I get 24 and highway I get about 26.5. I'm on my second tank. My first tank was 22.7, so I'm happy with that considering it's going up.

A couple weeks ago I made a little road trip into Ohio for a couple things, the trip was 170 miles and I averaged 42.3 for the whole trip. I was going right around 3-5 above the speed limit ( 68mph) and it was all highway. Non the less I was impressed.

Last week, one way about 120 miles, fresh fill up, about doing about 70 (Cruise set at 2000 rpm), pulled into town with 38.8. One time on short after fill up drive got to 43.9. I find that anything under 2000 rpms will gain me mileage on the highway. Combined mileage I am staying around 31 or so normally. I would agree that the best mileage is between 55 and 60 though. :thumbsup:

If your computer is telling you that your getting 40 mpg or 35 or whatever I have bad news.

Your not.

Gotta do the real math to get the real number.

PS: I am very satisfied with the mileage I'm getting.

i got 45.1MPG for a strip of 12 miles. and 38 for a strip of 39 miles(some back roads of hills, so thats why i was impressed.

I honestly got 46.2 miles going 60 miles. I was averaging 55-60 miles per hour and I was getting passed by everybody, but I pulled it off.

Exactly!! We just completed a 1500 mile trip from Indiana to the Smoky Mts. and through the Virginias. The computer told me that we had averaged 36.9 for the trip. I had kept my gas receipts so I did the math and the mileage was actually 32.1 which is still good considering the terrain we traveled through.

Agree - I computed it manually on my last tank (100% city driving) and the computer said 27.2 but my manual calculation showed 25.0. I'm still happy with that for 100% city driving.
