Jeep CRD

[GAAN]

complaining about the fuel mileage on jeeps is like complaining that a funny car wont hold a 1g turn

fact is the new Jeep JK has specs that kick the old TJ/YJ/CJ's ass.


JK's are capable. Their paper specs look impressive.  The driving experience though, as you said is lacking. I also don't expect great things out of Jeep fuel economy. I do think that certain things could be done in the design to improve it. Diesels are more efficient, which is not a bad thing.  To get back on topic, I have wanted a diesel jeep for a long time. The torque characteristics and potential for longevity inherent with that type of powerplant make a great deal of sense. They would also easily kick the ass of the current engine. I know it was time for the 4.0 to die. But there are far better options elsewhere. Just not under the Chrysler umbrella.

agreed, I would love the diesel in my TJ

but in the JK
(already carrying the extra 1000lbs)

The CRD is 300lbs heavier than the 4.0 gas motor
(from everything I can find which isn't much)

is the torque and fuel mileage going to be able to overcome the extra 1300lbs?
(not including the added weight of upgraded suspension and drive train)

Yes.

[GAAN]

Yes.

Awesome

I will now spend my free time pining over this Mod

My liberty CRD had never lacked for power but they have been plagued with transmission problems.  I am not any kind of authority on transmissions but perhaps the transmission they used could not handle the extra torque developed by the diesel.  My tranny had two recalls, one of which was to detune the engine to reduce wear and tear on the transmission.  A few months ago, I was having other transmission problems and they ended up replacing it completely.  Fortunately, I had about 200 miles on the warranty yet.

Its been about -2F here in the mornings which has required plugging in the jeep for starting.  It seems to start well right down to 0F but once it gets below 0, it's not even worth trying without plugging it in.  Several hours of heating and it pops right off.

I wish someone would build a couple of great vehicles around this wonderful engine instead of trying to shoehorn it into some existing platform like they did with the Jeep.  It would make a great midsize car or midsize pickup engine.

That engine was made for the Liberty by vm motori.  No other vehicle has one.  It shares the bottom end with some industrial eq but the top end and efi are all unique to the liberty.  Of course the crd system is licensed from benz.
