Autoblog drives diesel Wranger, Grand Cherokee

http://www.autoblog.com/2011/04/27/...ngler-unlimited-diesel-first-drive/#continued

Autoblog editors were invited to drive the next-generation diesel versions of the Grand Cherokee and Wrangler, as sold in Europe. They loved them! Some details:

Grand Cherokee: 3.0L V6 turbodiesel, 406 ft-lbs of torque, 0-60 times faster than the 5.7L V8 gas motor [correction: that's faster than the 3.6L V6 gas engine], projected 32 mpg on the highway, price estimated to be $39K for a 4x4 in Laredo trim.

Wrangler: 2.8L 4 cylinder turbodiesel, 302 ft-lbs of torque, 36 mpg when using the 3.21 final drive, maybe 32 mpg when using the 3.73 final drive from the Rubicon. The 4 cylinder motor is not as refined as the V6 in the Grand Cherokee, but that's in keeping with the Wrangler's image. Price estimated to start at $29,500 for a Wrangler Unlimited 4x4 in Sport trim, or about $4000 more than the gas engine Sport.

If nothing else, this means that Jeep is seriously evaluating the diesel engines for use in North America.

I got the 'we are working on it' response at EJS this year. I heard Euro VI and the USA emissions will match close enough to make it work.

The new Euro V wrangler is fantastic. It should have been offered in the USA. While jeep is having a hard time introducing the diesel in the USA, it's just as much the fault of the EPA for making the diesel emissions oddly hard to meet.
Particulate emissions seem to be the biggest concern in the USA?

Euro spec Rubcions have 3.73s?

With the new automatic I think they just about have to. The new auto has a really short overdrive compared to the old 545 automatic.

I think the euro diesel Rubicon uses the 3.73 final drive. That's because the diesel doesn't rev as high as the gas engine. With a 4.10 final drive, you'd have a diesel with 55 mph top speed. The diesel produces enough torque to pull the 3.73 at low rpm.

I am finding it hard to get excited anymore about Jeep, Wrangler, U.S. market and diesel all being used in the same sentence. Maybe if Jeep ever actually offered it here I might get excited but Jeep has teased me to many times now to even get me interested. A four door Wrangler Rubicon with a diesel and manual trans sure would look sweet in my driveway though.

major drool over that mpg

Why does Jeep just not get it? Every forum you visit, motojournalists and pretty much everyone with a clue wants the wrangler with a diesel. And yet jeep continues to play the "not enough interest" crap.

To Jeep: Build them and let the people show you there is a market.

Does the euro spec engine pass EPA regulations?

The EPA and CARB HATE diesels, and this is based on nothing factual.

The guy who put together the report for CARB, which has a lot of influence on the EPA regulations and policies, wasn't even a real PHD!

I would LOVE to have a Diesel Wrangler unlimited.

Euro V does not meet current USA diesel emissions. It comes close, and even falls on the Tier 2 table I think, but it doesn't come close enough. The impression I got for Jeep, AEV, and others is that in order to get the diesel in the USA your going to have to have a particulate filter AND an after-treatment fluid.

It is as much the EPA's fault as Jeeps fault.

Euro VI and USA diesel emissions are suppose to be similar enough to work.

Remember, as good as this diesel is, and its GOOOOOOOOD....it will no longer run on 'international' grade diesel fuel or bio-diesel in high percentages. I would like to hear what people from the USA are doing with there 2007+ diesel trucks when they go south of the border?

Most people I know, in the offroad racing world, don't. There are some programmers and DPF delete kits out there that help, but in general the new diesels do not like the diesel south of the border.

But then most of the guys I know have 7.3L powerstroke powered Ford Superduties.

I am a huge fan of Diesel motors, and would like to see them in many more applications here in the US. However, I stumbled across "Diesel Exhaust Fluid" the other day in a truck stop. Maybe this stuff is old news, but I couldn't believe my eyes... I thought it was a joke, like blinker fluid or something. If you aren't familiar, take a moment to learn about DEF and the 2011 Ford Trucks... it's boring... but seriously watch the whole thing and then tell me if you EVER want to have to manage this crap (http://motorsports.broadbandsports.com/node/39434)

Now I have no idea if a Jeep with a diesel would be subject to the same government rule regarding DEF; but if it was, I would NEVER buy one. I'm sorry, but DEF is the final nail in the coffin for me. It used to be that a diesel motor was a simpler, more economical engine. However, with the recent smog regulations, the modern diesels are NOT the same simple, hassle free motors of yesterday. Run out of DEF? Sorry, you can't drive your truck... It doesn't care if your 10 miles up some wash in the middle of Death Valley in July... you are screwed.

The government is OUT of control, in so many aspects. Sorry,rant over... But I'm just not sure everyone is aware of all the crap diesels have been subjected to over the last few years.

I really don't get the anti-diesel emissions control bent of this thread in particular, and this site in general. What is wrong with cleaning up exhaust? I mean really?
