There already is a new 3.0 liter in the Grand Cherokee or it's coming out soon, saw it in Off Road Adventures a little while back.

If you mean a 3.0 L turbo-diesel V-6, then yes, it's been out a year or two. I am looking at an 07 GrandCherokee with the CRD engine. I think it gets 20 city, 25 hwy. But it has the power & torque of a V8 gas engine.

Plus my neighbor will only drive diesels because he makes his own BioDiesel for less than $1/gal. I've watched him do it. It's not difficult, but the process takes a little time. He's making fuel now that he can use in a few weeks. But his VW turbo diesel gets something like 45 mpg on the hwy so he won't need it until then, hehehe

You must have got your fuel consumption wrong, Bubba. We just keep seeing more and more imports hogging the road. Pretty soon the BMW parts are going to be 25 percent what we pay for Mopar. You can't be serious!

You get 70mpg???

I was wondering about that too. I think a Liberty with the CRD engine gets around 21 city and 26 hwy.
How is his getting 70? is that Kilometers/decaliter?

My dealer said that's why there will not be a diesel WK for the 2009 model year so I bought an 08. He also said there will be a diesel in the 2010 version of the WK, but not a Mercedes diesel.

AND the LDD is back. Cummins Plant 1 here in Columbus IN is gearing up to start pumping them out either next year or the year after. I know for a fact there is a Chrysler oil pan, I work for the company that did the tooling for it.

A Diesel in the new Jeeps would be awesome preferible by Americans produced on American Soil, even if Mercedes gets the bid to put there Diesels in Jeeps, hope they build them here. What would be really awesome is if Chrysler or Cummins or Vm would capture the aftermarket and build affordible diesel engines for conversions.

But one could only dream. :[

Cummins is currently the only one to pass the next level of emissions, that I'm aware of.

I thought it was already confirmed that the VM Motori diesel currently being used in the WK2 CRD is 50 state compliant and will be available here for the 2013 model year. Why would they have another diesel?

[mike_dippert]

I don't know about use in a Jeep, but considering Chrysler's relationship with Cummins (Ram Trucks), I bet they would prefer to use Cummins products in more of their vehicles. Up till now, the 6.7L was the smallest engine Cummins made, which kept it out of SUV's.

[Marauder_Pilot]

The 4.2L diesel won't be coming to Jeep any time soon. If/when we do get diesels, they'll be VM Motori ones, because they're a more suitable option for European markets, and Jeep isn't going to offer two different diesels depending on markets without a good reason.

And 'Because Cummins' isn't a good reason, especially if you know about VM Motori diesels (Hint: They're awesome)

HOWEVER, take a look at Ram's latest announcement: The Tradesman 1500 HD. It's a Ram 1500 Tradesman with the frame and suspension from a 2500. Now start thinking of THAT with a 4.2L diesel. Yes, we may be looking at diesel-powered stripper Rams for under $30,000 next year.

EDIT: And Mike, Cummins makes tons of smaller engines. Most of them would already easily fit into cars and trucks of any size as well. It's just that they're only certified for industrial and off-highway use right now, and it's not worth certifying them for road vehicle use without a plan from a car company to do so. The 4.2L was originally developed for military use itself-it's only finding its way into regular trucks because Nissan and Chrysler are, presumably, coughing up the money for tooling and certification.

Emissions legality has been a driving reason why smaller diesels are not more prominent in this country. Cummins makes all sorts of small engines, but they've never been US road worthy, for one reason or another. The LDD is intended for vehicles with a GVWR of 8500# or less, which almost all small trucks and SUV's are in that class. I don't know squat about about the VM though. Would it still be as amazing with all the emissions crap packed onto it? With 2014 fast approaching, and the final tier of emissions requirements, it would be in a(ny) manufacturer's best interest to wait for an engine that's ready for those standards.

Edit: Chrysler pumping a lot of money toward Cummins to certify their smallest US legal deisel, which can fit in the same place as a V8... that sounds like a "b/c Cummins" thing to me. You think they would do that JUST for a single vehicle in mind, even if it is the RAM 1500.

And for the record, I'm thinking whatever engine is on the euro version, will go in the US version. But only if it can be easily adapted for the tier 4 requirements.

The VM Motori is already 2014-legal. VM Motori is to Europe what Cummins is to North America, they're true industrial-strength engines. With all the emissions regulations in place and adjusted for NA EPA emissions cycles, the 3.0L diesel Grand Cherokee is good for about 30 MPG combined.

The 4.2L came originally around for pff-highway and militay applications. However, Nissan came to Cummins and asked them to get it certified for the Titan. I suspect that, what with the Titan being a distant last place in full-size truck sales, and given Nissan and Chrysler's history of joint ventures (Remember the next-gen was going to be a Ram with new badges), either Cummins approached Chrysler or vice-versa, thinking that Nissan alone couldn't make a sufficient case to pay for the certification and refitting and brought Chrysler in as well.

This is all speculation so far, since we still don't know for sure that the Ram 1500 will be getting the diesel.

Completely agree. Don't hold your breathe for a Diesel in a JK anytime soon that's emissions legal.
