Diesel Cherokee and Wrangler test drive

If this is a repost sorry

http://www.autoblog.com/2011/04/27/j...l-first-drive/



I love TJ's and would love to get my hands on this powertrain to swap in or buy a JK with this powertrain if I can't do the first. 32mpg? The best hyper milling I can do in my TJ is 17 combined and 21 highway

I hear the Cummins 4bt swaps get about 26 mpg or so? I guess that's the only benchmark I can come up with for this diesel

I just emailed jeep asking for the new diesel to come over at this link
http://www.jeep.com/wccsapp/universal/J/index.jsp

Dont you think everyone should email them and tell them you want one (assuming you do)?

My lil'MJ is shortbed 2WD and it gets 14-16MPG's . . . Seems to be quiet affordable and reliable.
I don't seem to have good luck with things that get 20+MPG's I seem to always wreck them

6-9mpg I get outstanding performance n durability, 10-15Mpg performance or reliability fades off 15-25mpg Performance and durability both tank vehicle fails within months . . .

Yeah I heard long term reliability isn't the greatest on direct injected vehicles, diesel or gas. Extremely high pressures, something has got to fail eventually or at least you'd think so

Ya as much as I would love to see a 25-35mpg Jeep, Its only going to help run fuel costs up.
These last few price spikes have been from US using less fuel so up goes fuel to maintain their profit margins . . . Its all a gimmick game when the nation got 10mpg = $1.75/Gal now we get 25-35mpg = $4/Gal

Either way Fuel costs n fuel efficiency are related

This is true you would be able to go further between fillups allowing for less stops for fuel on long trips/rides . . .

You're joking, right? GDI is so new that nobody really knows, but there's plenty of history on diesels (which have been direct injection for 60+ years).

on paper, the numbers are better than a the 3.6L pentastar




On the road, the Italian 3.0-liter V6 CRD in the Grand Cherokee Laredo 4x4 from the Jefferson North plant in Detroit is as smooth as butter. The 237 horsepower is, of course, fine. But it's the 406 pound-feet of torque between 1,800 and 2,800 rpm that gets our juices flowing. For one thing, the 3.0 CRD can accelerate a Grand Cherokee 4x4 to 60 mph in just 8.0 seconds, which is darned close to the estimated time for the 5.7-liter V8. It also has the same 7,700-plus pound towing capacity. EPA numbers would need to be run certainly, but by our conversion, the 3.0 CRD should be capable of 22 mpg city and 32 mpg highway. That's a far cry from the 16/22 mpg estimated from Chrysler's new 3.6-liter V6 Pentastar engine with the 4x4 setup. These numbers put the CRD's potential total range from a full 24.7-gallon tank at right around 800 miles.
