i don't think its so much the engine be innefficient as it is the fact that the jeep is a big arse brick. its heavy compared to the fuel efficient cars of today and its not aerodynamic at all. so even in you put an "efficient" motor in it, it would still get bad milage. to be honest, i think the best chance we have at decent milage would be proper gearing and a hemi.... honestly, the hemis with the fuel management thing that cuts out 4 cylinders when cruising would be the way to go. they have enough power to get the box on wheels jeep design rolling without having to really step on the gas, and would cut out 4 cylinders on the freeway... plus it would just be nice to have a hemi .... but i'll keep dreaming til that happens.
Whatever, the last thing that I need is for Jeep to start putting Hemi's in the Wrangler, then I'd be trying to figure out how to break it to my wife that the Jeep that I waited 6 months on is going bye-bye.

I also think the 5.7L hemi w/ mds could easily get similar if not better gas mileage than the 3.8 when driven right. Perhaps there's hope the next gen 5.7 hemi (soon to be available in the '09 ram) will make it into the JK later. It gets 4% better gas mileage than the current one, oh and has 380hp.

I disagree! It is all about efficiency!!! To use an analogy, you don't put a larger furnace in your home to heat it cheaper...no, you put a more efficient model in. If you wanted to turn it into a blast furnace then yeah the bigger unit would be better, but it would cost you more to operate on a yearly basis as opposed to running a smaller more efficient unit. Not to mention that the Hemi really isn't very efficient either! Even the next gen 5.7L only puts out 380hp. Come on, that's 66.67hp/liter. Our little 3.8L gets 53.16hp/liter. PATHETIC!!!!!!!! IMHO!!!!!!!! Several cars on the market get 100hp/liter and even 150hp/liter, now thats effiecient...any they still get the mileage too.

I think that was a line of shit by the Crappler Corporation as part of the "concept" because they never proved or demonstrated that it could actually get that kind of mileage. You could damn well bet if that thing could get that kind of mileage it would be in production. If it could get 80 mpg . . . it would be in production . . . if it could get 50 . . . it would be in production . . . and my ass would be riding in one to and from work.

Hell, stop moaning, in the UK we pay £1.21 per litre, thats $2.42 per litre, and with the diesel engine, (and the only thing changed is winch bumper and Pro comp tyres, which are the same diameter as stock), i got 19.7 mpg the other day motorway driving.
And just to rub salt into the wounds, BP and Shell have had record profits for the first quarter, with BPs up 48%.

The 3.8L may not be great, but it is certainly more fuel effiecient than the 4.0. I get about 3 MPG better economy in my JK than my TJ, despite my JK being bigger and heavier, with larger tires and heavier, stronger axles. Also, while there may be more high-tech, fuel efficient V6 engines available, they must be able to stand up to the usage that a Wrangler is designed for (off-road, etc).

I don't think there's much doubt that Chrysler can make a vehicle that gets 100mpg...it's a matter of being able to reproduce it at a cost that Joe Public can afford. The Renegade concept had 2 electric motors (one for each axle) along with a Bluetec Diesel. I wouldn't be surprised if they spent 500k-1000k in R&D and production costs for that vehicle. So what! They can't mass produce it for less than 100k probably, so now what? "Hey everyone, I save $3000 every year in gas because my Renegade gets 100mpg...just think, it'll only take me 23 years to earn back the extra 70k i spent." I hardly ever get excited about concept vehicles, because they rarely represent something that will eventually be available to the public.
