I've only had my CRD Overland for a few weeks- only done around 800 miles so it's barely run in. At the moment I get around 22 MPG in city driving. I have no doubt I'd be looking around 30 MPG + on the highway.

Please read my post. I don't care about 60mph mileage because I never go that speed.

At 60, you will get the EPA rating in every car I've owned for the last 6 years (or maybe 1-2 over). In the V8 Jeep that's 20. What is the Tourag, 32? OK fine. (I looked it up, it's a very respectable 28, and the Tourag is smaller than the Jeep).

At 80 with ski pod on top and full vehicle I average 17 both into and with the wind (average) in early April (summer will be a bit better).

Older Jeeps were lighter I suppose and smaller, some had 2wd as an option or switchable. The new Jeeps are AWD, heavy, and big. Just like the MB and BMW's which are listed in diesel form as mid 20's hwy EPA... But at 80 with a pod on top fully loaded, what do they get.. This is my question. I'm not bashing diesel, I just think it will be more like 23 than 32. So for my personal deal, I'm comparing 17 to about 23.

Using my calcs, this is about 5-6K$ savings with D by 60,000 miles, fwiw.

As far as urea, I still think the Jeeps will have it in 2013 until I hear some educated voice otherwise. And if the urea is frozen long enough and not being injected into the engine (exhaust??) due to multiple short trips it will eventually send a fault and shut the car down (prevent restart or something). I seriously doubt BMW would do this if the EPA didn't make them. I'm not saying I plan on ice road trucking, but the last thing I want is a car that won't start or keep running because some California boogerpicker thinks I'm hurting the environment when I'm stranded in -20F. This along with other minor unpleasantness of D make me lean toward keeping my V8... But I will be testing and considering the D when it arrives.

Smaller maybe but not much lighter. Per VW website curb weight for diesel version is 4974 lbs whereas curb weight for diesel WK2 is between 5008 lbs and 5191 lbs according to Jeep Australia.

Before getting the WK2 I lurked for a while on some Touareg forums and every diesel owner reported better millage than EPA ratings. Typically 20 city and > 30 highway. I did test drive the Touareg and was very impressed with it but in the end the Jeep was the better deal.

Re: Diesel Grand Cherokee Coming to US!

I think Comnjeep is correct. I have read that the Touareg TDI does use an urea soulution.
I think the urea solution they use is called AdBlue & there may be issues with it freezing.

Re: Diesel Grand Cherokee Coming to US!

I'd also add, it's really good to hear about the Diesels from our friends around the world, but I think the Diesel Cetane (??) rating is different in different places..

For example, the Ford Mondial 6MT Diesel I drove in England 4 years ago got an awesome 56mpg hwy and was a sweet car and engine... But here in the states, a Jetta or Passat Diesel gets about 44. I don't think that's the car, It's the fuel, imho.

Of course, the fuel in England was about 9$/ gal, so go figure.

Re: Diesel Grand Cherokee Coming to US!

If the diesel jgc does use urea injection I would assume it would function like the cummins

Re: Diesel Grand Cherokee Coming to US!

There is a lot of noise out here about the diesel JGC. Overseas they do not have a EPA that is run by a bunch of tree huggers with unlimited power over everything! The problem with diesel in the US is the ULS demands made by the EPA. The particulate filter requirements made by the EPA and the CAFE standards forced on our automanufacturers by...you guessed it... the EPA! Diesel is about 40 - 70 cents more per gallon, then you have your piss bucket you have to fill every tank... another 20 bucks. So your average cost is going go be about the same. The manufactures will build them, some of you will buy them and all they have to do is "OFFER" them and have them in cluded for their cafe requirment calculations. That is why you now see the FIAT death boxes again being sold in the US. Chrysler will use them to meet the mpg standards being ram rodded down by the EPA. After november we hopefully see the federal governments wings clipped and the EPA disbanded. I also want to say to some of the posts here... There is no way your CRD will EVER keep up with a HEMI....Not in your best wet dream! I don't know what your smoking but it must be good!

Try about once a year....never know about the CRD being as fast or faster than the HEMI....the HEMI is nothing to get all excited about.

Re: Diesel Grand Cherokee Coming to US!

I can assure you there is NO UREA system in the CRD. It EURO5 compliant so it out greens even the most green EPA regulations. You guys in the USA have it easy in comparison to the EU and AU when it comes to tree huggers. While the fuel may cost more, you go a lot further than a v6 or Hemi on a tank.

Overseas people keep saying that, but do your BMW, VW, Audi diesels have urea either? European BMW diesels do not but they add them in the US.

I have no idea about australia rules but in the US:

Diesel fuel quality sucks
all diesels I know of need urea to be 50 state (california) compliant.

So just because you have 8$/gallon gas and cheap high quality diesel doesn't mean that's what we get.

I hope we fix our situation, but until then, I want people to know the truth as I want the truth to make a decision that is best for me... in the backwards 'ole US of A.

Re: Diesel Grand Cherokee Coming to US!

I have owned two US version clean diesel models, a 2009 BMW 335d and a 2011 VW Touareg TDI. Both of these vehicles have had zero problems with US fuel or the SCR (urea) systems. These SCR systems are heated (active tank) to avoid freezing.

The 2011+ Touareg is almost identical in size and weight to the 2011+ JGC.

Some who have posted on this thread haven't a clue of what they are posting. Everybody reading this should check the facts for themselves.

Re: Diesel Grand Cherokee Coming to US!

Dont forget in the EU their tax policy favors diesel over gasoline as a fuel. Please dont mention this to Comrade Barry or he will try that do.

The big question with urea is can the user add it or does it have to be done at the dealer and what is the cost.

I dont want to know as a former BMW owner what a BMW dealer charges for a Urea service but am I guessing at least $200 if not more.
