yep. they've got to. The new Toy has got 385? and Dodge and Chevy keep upping their #'s. I almost wouldn't be surprised to see some Mustang technology come to bear to help out a little. (dual overhead Cam maybe?)
when does the 6.2 become available? I will be buying a new truck in the fall of 2009, and I really want the diesel if its available, but I can settle for a 6.2 in a 1/2 ton
Yeah i kno that i have the 5.4L V8 i was wondering about the new diesels and the hurrican engine.
Still can not understand the facination with diesel products. Trust me on this one, it's not a driving utopia nor are they user-friendly in the US. Had many diesels over the years, both good and bad ones. In fact, I have one now I would like to sell/trade, or just having it stolen would do me a big favor. The fuel savings & power benefit rarely balances against the expense & nuisance factors. Take a detailed and long look at any new diesel offering before buying. The added expense & negative effects of the '07+ emission changes will change the entire game, not for the better.
I agree with Jeeper on the diesel issue. Unless your going to be doing alot of heavy towing, drive an excessive amount of miles a year or are going to keep your truck for 200K + miles you are wasting your money with the diesel option. Everyone thinks that a diesel engine is cheaper to run because the fuel mileage is better and the motor lasts longer, well that thought is partially true; if you trade your truck /car every 100K miles or less you are wasting your money on a diesel because they are desinged to last for 200K-300K miles(with proper maintinance) before a major overhaul is required,and it takes that many miles of use to offset the $3,000-$5,000 cost of the diesel option, also, in a compact car like a VW or a small Suv like a Liberty a diesel option will get you another 10-20 MPG but in a truck or large SUV the mileage difference won't be that large and with diesel being higher priced than gas right now(in Iowa diesel is about $.20 cents higher than gas)you will about break even on gas expenses. On the maintinance side of things a diesel costs more to properly maintain than a gas motor, you have a larger oil filter and a larger capacity oil pan on the diesel and also you have a fuel filter/water separater that needs to be changed more often than a gas motors fuel filter, and you also have a coolant filter that needs to be changed and you need to test the coolant at every service interval to make sure the SCA levels are in check in order to keep the liners of the motor from being pitted from corrosion. Also, it is recomended that the overhead be adjusted every 100K miles, and diesels are also more prone to having injector problems than gas motors. Another thing that needs to be addressed is that if you live up north you need to make sure you run the right kind of fuel in the winter or you run the risk of having the diesel "gel" up which leaves you stranded, this is done by mixing anti-gel additives to the #2 fuel or blending #1 and #2 diesel together, both of which increases the cost or every fill. The new '07+ emission requirements will create a whole new set of problems that will need to be addressed by the industry and the consumers, there will be an extra particulate filter that needs to be serviced regularly, and the combination of the increased complexity of the smog reducing add ons to the motor and the Ultra Low Sulfer diesel that is required in these motors will reduce the fuel economy and overall life of the motor and make them even more to maintain than they already are. Sorry about that long post, but I can never understand why peoplr that are looking for just a daily driver would want the hassel of a diesel, I figure it's because either thay think it's cool to have a diesel or that they really don't know what they are getting themselves into when they buy a diesel.

I know they will last longer,I've seen some with 500K + on them, and I run the diesels in my semi's 900K-1million miles before I get rid of them, I just put 200-300K because I think that is what it seems the industry uses as a standard to keep people happy because not all people will properaly maintain their diesels so they will last as long as they should.
the 4.4 L is 330 HP and 515 Ft Lbs....and the 3.6 is 277 HP and 470 something Ft Lbs
that would be awesome.....simple as that!!!

I will chime in again as this is another positive misconception. I too have seen diesels go a million miles. You won't see that out of this new generation of diesels due to the exhaust gas recirculation. I work for a major public transit provider that runs Detroit Diesel Series 50 "Clean Diesels", another million mile engine that is lucky to go 80-100K miles between rebuilds. Why? Because they recirculate abrasive soot through the EGR system that is scouring the upper engine (no different than running without an air filter). That is why they require the new ULSD fuel as it makes less soot. I won't get into the plugged EGR valves and VGT/turbo failures which are routine. I too have owned a bus fleet, know how to maintain a diesel and have rebuilt a few in my days.
The Liberty diesels emissions package is a clone of the Series 50 (it is also a DDC product). It too is prone to EGR failures and some are now seeing turbo issues, mine has been puking oil into the charged air cooling since day 1. Where is DCX through all of this? In denial, parts are on chronic back-order and their dealers are absolutely clueless on how to fix these things if you can find a dealer willing to work on one. I know exactly how to maintain a diesel, this one has to go!
As for fuel economics, the Liberty might pull high 20's under ideal conditions. The best I've seen is 28 mpg on a 900 mile trip. Normally I see @ 22-23 mpg, sometimes as low as 20 running almost exclusively expressways. Discount this for the 15% premium I pay for diesel fuel (not incl. the additives to compensate for poor fuel quality in the US) and this little SUV is as expensive to run as my '97 Chevy 1500 pick-up. Do yourself a favor, keep your gasser F-150.
