would the 3.7L V6 be the same one from the Dodge Ram 1500 pickups. if so, I wasn't any more impressed with it that I am with my JK. It was louder, more rough, not any more fuel efficient, and put any more weight into the back of the truck and it felt like a 4 cyl. I have pulled the same trailer and load with that truck and now with the JK and Jk did just as well as far as power, even on the low end, now handling and suspension with the same load probably went to the truck but that's a whole different ballgame.
The 3.7 liter I had in my Liberty was an absolute pig on fuel. Much worse than my JK.
I did like the interior though.

Wow, our Liberty gets about 23 on the highway and just a little less in town. I've always run synthetic and watched my tire pressure. I can't say enough good things about the 3.7 . I think it's crazy how different everyone's vehicles are when they come from the same factory.

My boss has an 05 Liberty and when I was looking at the JK I was talking about the gas mileage and he just laughed at me. I told him that it wasn't horrible and if I could get 15-17 MPG I would be happy. He said that around the city...cause we live in Chicago, he only gets 10-12 MPG. I was scarred, but I was willing to accept it since you don't buy a Wrangler for the gas mileage. 3 months, 5500 miles later (trip to Florida last month), I consistantly get about 17 MPG around the city.
I come from a long line of 4 cylinder cars and 8 cylinder work vans so I don't know what to expect power wise, but I am satisfied with the 3.8. My only fear is that it won't become the legacy the 4.0 liter became. I don't want to be known as the guy with the 3.8 liter they only made for 2 years or something before they upped it to 4.2 or something else to make customers happy.

That's weird. My fiance's '06 Liberty does better than my JK fuel-wise, and she has a lead foot. I drive for economy and can nurse 20-21 mpg out of the JK and she still edges me out. The Liberty is much more responsive than my JK, especially on the highway. Some of this I attribute to the engine, but since they are totally different platforms there are other variables that must be considered (so I can't put it all on the engine alone).

It is weird, though I suspect that the driving/maintenance habits of the people and the environment they drive in are a much bigger variable than the vehicles themselves.

We've actually owned 2 Liberty's. We had an 04 with the 3.7 and 4.10s, and it was horrendous on gas, but it pulled my wife out of some "unplanned" off roading one winter and she won't drive anything else now (other than my Wrangler). We ended up trading it in on an 06 Renegade with the 3.7/3.73 gearing and it is great on gas. They changed the transmission in 06, and it's actually the same one our JK's have.
