Grand Cherokee going diesel

For those of you who are considering a new tow vehicle, a new option will be available in the first quarter of 2007. DaimlerChrysler will be adding a diesel powered Grand Cherokee to their offerings. The Grand Cherokee CRD will have the Mercedes 3.0 liter common rail turbodiesel V6 rated at 215 HP and 376 ft/lbs of torque. EPA is 19/23 with a tow capacity of 7400 lbs. I'm sure there will be a lot more info available very soon.

This may be nice TV for the SUV crowd. Any thoughts?

John

I don't think there is much to be excited about, afterall that engine will only last for 500,000 miles or so..... I hope they are not using one of their American Transmissions. Now if only IH would bring back their wagons...

4wd?

Strange thing that I see at Specs for the Grand Cherokee website is that only the 4WD Limited has the 7200# tow capacity. All other 4WD models list a 3500# tow capacity. (other than Limited, the 2WD models are listed at 6500#) Can anybody with an owner's manual verify this for our readers? You'd think a diesel might have a good tranny for cruising/towing. It will be interesting...

The same website lists existing (non-diesel) payload capacities from 1489# to 1574#. Due to actual trailer loading increasing published empty tongue weights, I'd think this payload range would max out with about a 22' to 23' newer (heavier) Airstream. By 'max out' I mean to say that the sum of fuel, driver, passengers, hitch bar, tongue weight, and any other on-tow-vehicle weight or options cannot exceed the vehicle's payload. Even with diesel this same chassis can't become a honkin' big tow vehicle.

How big?

Bob,

I have been looking for more info on the new diesel models but so far I have had no luck. I think we can safely say the diesel models will outperform current non-diesels. I was thinking the primary target for the Grand Cherokee CRD as a TV would be smaller (16'-23') Airstreams, folks who are looking for more torque and longer living power plants. A fully loaded 25' may be pushing it, mostly due to short wheelbase.

It does seem odd that the current models have such a wide range of tow capacities.

John

Right on John! It's like we're reading from the same script. That is the value of the Forums in determining best practices!

drive system

After a little more research, the new diesel Cherokee will be mated to the new Quadra-Drive II , 4 wheel drive system. So, yes, it will be a 4X4.

Just curious, would anyone in the forum buy this TV?

John

It won't replace my Expedition....I "need" the 8,600-8,950 towing capacity for my trailer.

We have a 2000 Jeep GC for a daily driver (it couldn't hack the Airstream) and it is a nice vehicle.....I would buy another BUT

Needing towing capacity, I don't think the new Jeep will "fill the bill".

I would. I might...need to check it out first. My friend has a Grand Cherokee V8 and tows his Flying Cloud with it, is totally satisfied.
I woul dneed to see the vehicle up close. Might it be the Commander model, with the extended wheelbase?
I have had nothing but excellent luck with Mercedes engines. Our family car ( 3.0l 6-cyl) is somewhere near 400k miles, with no apparent end in sight.
I am happy with our Suburban as a tow vehicle right now, but would like to ge something a little smaller next. btw. it, too has treated me very well so far. ( 135k miles)
Mercedes Benz has tremendous experience with smaller Diesels, as a major manufacturer of car Diesel engines, and a huge assortment of light duty, Diesel powered vehicles. ( the Sprinter is just one example, there are many more like it)

I think I see more Grand Cherokees behind BA motorhomes than I EVER see in front of a travel trailer. Today in making a loop around Georgia, I saw one van pulling an 80's 25-or-so very like Driftwood's. I saw THREE big motorhome hogs towing Cherokees.

Diesel Jeep for TV

I might trust the diesel Jeep for a Bambi. I don't think that I would want one for a 25' and up.

The regular Hemi in the new Charger has 350hp and 350ft-lbs of torque. In the Grand Cherokee, that engine would be close, probably 330hp and 345 ft-lbs. So the diesel out torques it by 30 ft-lbs, but loses by 115hp. I think the gas engine would blow its doors off. It'd be like comparing about a 2000 Cummins Turbo Diesel to the 440 magnum in my '69 Charger. The turbo diesel might make 500 ft-lbs of torque in that year, but the 440 made 480. And it's 250 horsepower on the diesel to 375hp in the car (closer to 500 now )

The hemi has cylinder deactivation now too, so you get pseudo decent milage with it.

On the Jeeps being towed, from what I understand, Jeeps and Saturns are two of the most popular "toads" because of their transmissions. You can stick both in neutral by some means or other and tow them with all four wheels on the ground and not destroy the transmissions. Most other cars you can't do that.

My buddy has a Land Rover Defender 110 with their diesel. Neat truck, but I could beat him on my Schwinn. That thing is a real dog. Good off road though.

Sprinters are cool. I want one!

GOT ONE!!!! It's amazing what you can do with only 155HP and 225 FT/LB of torque with a CGVW of 13,500 lb.!

I am going to wonder about availability...when the Jeep Liberty was "supposedly" available with the diesel we went looking, never found one for sale and were told they weren't available for special order either. I did see one...at a traffic light.
