Take a quick look around the light-truck market, and it's clear that diesels are the hottest thing on dealer lots right now - but oddly enough, it's not currently possible to get an oil-burner in a full-size SUV. Jeep has apparently identified this massive hole in the market and will announce later today that a diesel Grand Cherokee will be available for the 2007 model year.

Details are a bit sketchy at this point, but it sounds as if the vehicle will use a 3.0L Bluetec common-rail diesel from Mercedes - an engine that makes 221 HP and 376 lb-ft of torque. Fuel economy is said to be improved by "30 percent" (we're guessing this is compared to the somewhat thirsty Hemi V8), yielding a driving range of 425 miles on one tank. Towing capacity is also supposed to be impressive, but that claim will need to be evaluated further once we have more information. Like its smaller Liberty brother, the Jeep Grand Cherokee diesel will be shipped from the factory with a tank of B5 biodiesel blend.  

While it will be the only full-size diesel SUV available in the US when it debuts in the first quarter of next year, we have to remind Chrysler that it isn't the first (as they claim) - GM's Suburban, Jimmy, and Blazer were available with the 6.2L Detroit Diesel way back in 1982, and more recently, Ford offered its monstrous Excursion with a Powerstroke diesel engine until that vehicle's demise last year.

You can't drive a motor vehicle on Michigan's Mackinac Island, but that doesn't mean you can't make a major announcement about one.
That's what Chrysler Group President and CEO Tom LaSorda will do later today (4 P.M. EDT) during a keynote speech at the annual Mackinac Policy Conference-a big, big deal in Michigan where movers and shakers gather each year to talk business, policy and politics on the popular rock in the northern end of Lake Huron.
LaSorda will reveal to the group that the Chrysler Group will offer the first diesel-powered full-size SUV to the U.S. market. The Detroit-built 2007 Jeep ® Grand Cherokee equipped with a 3.0-liter common rail turbo diesel engine arrives in showrooms during the first quarter of 2007.
The Grand Cherokee's diesel engine is based on technology developed by Mercedes-Benz, which is the center of expertise in diesels for DaimlerChrysler. The Jeep Grand Cherokee diesel will offer class-leading torque, outstanding towing capacity ... and up to 30 percent improvement in fuel economy, giving it an estimated driving range of 425 miles.
LaSorda will announce that each diesel-powered Grand Cherokee will leave the Jefferson North Assembly Plant in Detroit filled with B5-five percent biodiesel fuel. Earlier this year, he told the Detroit Economic Club the Chrysler Group will endorse the use of B20-20 percent biodiesel in the 2007 Dodge Ram for military, government and commercial customers

      "16. We didn't get the Golf SDI here in the US. ;)

      I do own a 1985 Jetta naturally aspirated diesel, though - 52hp out of 1.6L."

      Lucky you!

      I drove a Jetta III TDI (the 1.9, 90hp, 180lb/ft torque) when my cousin had a Golf III D. Wait, it was just a "D", not an sdi. That Golf was a dog.

      Now in the US we'll never get the cool Diesel from overseas because of soot emission (and other crap) Plus, people hate Diesel, and you can't blame them when you've been following a ford F350 for more than a mile. Slow, noisy, stinky.

      Volkswagen beat them to the punch. The 2007 Touareg V10 TDI is available for ordering right now. I'd hardly call it "full-size" but then again, neither is the Grand Cherokee.

      Go back a few more years...

      Didn't the International Scout (or was it Scout II) have a diesel option?
      • 8 Years Ago
      Great. Now PLEASE let the USA get the 2007 Unlimited Wrangler with an optional diesel. PLEASE!!!

      Gotta agree with ku. The Durango/Aspen is the closest thing Chrysler offers to a full-size SUV. And the Hemi is beyond moderately thirsty.

      The 3.0 Bluetec (sp?) would certainly be far superior to the Italian diesel offered in the Liberty if the older tech diesel offered in the current E-Class is any indication. I was very disappointed by the Liberty diesel--it sounds, smells, and feels very much like people expect a diesel to sound, smell, and feel, which isn't good. Real-world MPG is also disappointing based on reports I've read.

      My review of the Liberty diesel:

      I'll be the first in line to test drive the new diesel Grand Cherokee. I've driven a 2003 Diesel Grand Cherokee as sold for years in Europe (with MB diesel engine equipped with 1st generation 1350 bar Bosch Common Rail). That MB diesel was disappointing in that it had not been appropriately packaged for NVH and accoustics. I was sorely disappointed with the Jeep Liberty and the selection of the Italian VM engine, and again, poor engine packaging for NVH. I hope Jeep takes a good look at the MB E320 CRD, the BMW 535d, and the Audi A6 d and accomplishes a diesel NVH package that surpasses gasoline, as the Audi A8 does at 70 mph (3 dB quieter in the cabin than the gasoline A8 !!).
      As for the idiot above who thinks ANY diesels are non-turbo, his comments need to be disregarded entirely.

      Isn't the Touareg diesel supposed to return? Never drove one, but the specs are impressive.
      • 8 Years Ago
      Chysler should take the lead ( in the USA ) with diesel engines, it has available with Mercedes.
      I would love to have the diesel in my Sprinter Van in a Durango/Aspen.

      Yes, the International Scout had a Nissan Diesel diesel engine option (Nissan Diesel being the actual name of the company which produced the engines, and yeah, it obviously was part of Nissan group). The inline six diesel was available from (about) 1978 through 1980, and I believe the last year or two, it was turbo-charged to boot.

      I recall seeing, about 12 years ago, an advertisement for "brand new" unused, new-old-stock, International Scout diesels which had sat in Arizona, unsold, since 1980. That would have been 14 years.

      Gas was cheap. Who wanted an "orphan" diesel SUV?! Clearly not many people, since it took over 14 years to clear out that stock.

      highway 23 mpg is a mistake.

      overland 5.7L 322bhp @ 5000, 369lb-ft @ 4000 5sp auto
      combined 15.4L/100km, 18.3 UK mpg
      city 21.3L/100km, 13.3 UK mpg
      highway 12.0L/100km, 23.5 UK mpg
      --------------------------------------------------

      UK jeep grand cherokee 3.0L crd 215hp @4000, 376lb-ft @ 1600
      combined 10.2L/100km, 27.2 UK mpg
      city 13.1L/100km, 21.6 UK mpg
      highway 8.6L/100km, 32.8 UK mpg
      ------------------------------------------------

      Well if 21.6 UK mpg = 19 US mpg then the multiplier is 1.1368421
      So if 32.8 UK mpg div/ 1.1368421 = 28.85... highway mpg

      Or if 27.2 UK mpg = 23 US mpg then the multiplier is 1.1826086
      So if 32.8 UK mpg div/ (above) = 27.735... highway mpg

      VW Touareg has been available with a diesel for a couple of years now, so it is not the first

      I went to the jeep UK web sight for this info:
      2.8L crd cherokee limited 161hp 295lb-ft.
      combined 28.5 UK mpg 9.9L/100km
      highway 34.4 UK mpg 8.2L/100km
      city 22.2 UK mpg 12.7L/100km

      Then I went to the jeep.com sight for this:
      2.8L crd liberty
      22 mpg city
      26 mpg highway

      I went through allpar forum to find this:
      The EPA ratings of 21/27 are on the conservative side by a point or two. I consistently hit 22-23 MPG city, and if you keep your highway speeds to 60-65 MPH 28MPG isn't hard to achieve.

      US gov findings 19mpg city mileage, sounds about right to me.
      It's still baffels me that highway mileage estamate for the US 3.0L crd grand cherokee is just 23mpg. I wrote to one of the people listed at cgmedia chrysler and asked if this was a mistake. They wrote back saying that the government findings are 23mpg highway. I sure hope they are mistaken and true mileage is closer to 26-28mpg for the highway.


      From the UK jeep web sight.
