Definitely good news. When gas is $4/gallon, the TJ boys (I'm one of them) will be crying about the I6. 18/25 FOR A RUBI 4 DOOR!

I would imagine the 2 door versions will come in a little higher in their respective trim lines.

Sure, you aren't gonna get the 27 any more than you're gonna get the 18 on a TJ. The difference is you might pull 24 on the highway instead of 15 - or a 63% INCREASE!!

This is hard to believe considering that the Nissan Maxima only get 20 city and 28 highway. The V6 in the Maxima is a way better motor than DC's motor and it's lighter, more aerodynamic, front wheel drive, has smaller tires, and many more things that would help fuel economy.

They're gov. #'s on the same test. Perhaps the Maxima's tranny and engine are configured for more pep and better acceleration times?

Bottom line: My TJ will be bye bye in the next year.

A co-worker has a mini-van with the 3.8. In 70k miles his lifetime average is 18 mpg. That includes city and highway driving of course. But I bet the 3.8 in the JK will be lucky to see 20 mpg. Granted that is better than 16.

You have to keep in mind these are guidelines not dead on balls #'s.75% of us will never see 18/27,,but then again %75 of us never see 14/19 in our TJ's either-(lol) It is just a # to give you an idea,I get about 15-18mpg in my 03 silverado yet my wife gets about 19-22 so there you go.

I am very apprehensive when I hear about fuel mileage in new vehicles. I average 14 MPG ( calculated out , not a "guess") in my 05 unlimited with 10,000 miles on it.

if they are saying 25 hwy, then most likely it will be 20.

I bought a 97 TJ when they came out. Sticker said 17 city and 19 highway. It 4.0L engine, was a manual tranny with the small tires and 3.07 gears. It got that mileage. I think it did better on highway.

If you stay with highest gears and smallest tires jeep offers, I think you can get close to the mpg of the sticker usually.

BTW, anyone know why jeeps stickers used to read 17 and 19 mpg back in '97 and '98 for the 4.0 manual tranny, and then they lowered those numbers for the same ride, it's now 15 and 17 mpg?

Isn't the 4.0 quite a bit more powerful now than it was in 1997? That could explain the difference.

I think you could be right, Back then it was 181 HP and now it says 190 HP. But some on the rubicon forum said that the older 97-99 had better or less restricted headers or something. Those guys say the older TJ's have a bit more power.

It didn't seem like my '98 had all that much compared to my new rubicon or any of the others I test drove.

I get 13 to 14 mpg in my 2003 Rubi. If all I get in my 2007 is 18, I'll happily take it and run.

That would be a 33% improvement. Or about a $800 per year for you.

yeah it will deff be better, and once gas gets to five dollars a gallon I will be saving like $3,500 per year, and the JK will pay for itself hehe ( at least thats what i am going to tell the wife...."we will make money by purchasing this new 07 wrangler......we would be stupid not to buy it).

seriously though; I know the mileage will be alot better than what i have now, its just that i have never owned a vehicle that actually got the advertised MPG.
