The smoking tease...

When we first saw the slide pictured above at Chrysler’s five-year plan, we jumped on it as the only seemingly positive bit of news coming out of that deeply depressing 7-hour presentation. We should have known better. Today Chrysler is reminding us why it always pays to be cynical about everything that comes out of the mouths and powerpoint slides of our friends in the industry: buying into the hype always makes you look like an idiot down the road. Jeep CEO Michael Manley brings the inevitable letdown to the Toledo Blade.

We have no plans at the moment for diesel Jeeps in North America, although one of the things I’ve learned in this business is to never say never. I wouldn’t rule it out, but specifically on Nov. 4, we were commenting on diesel in Europe.

But hey, there will be more special edition Wranglers!

    I wish auto manufacturers would just stop teasing me with their light-duty diesel product announcements that either get cancelled or aren’t coming to NA!

    I wouldn’t buy a new Wrangler unless it had a diesel. But I can understand if the particular diesel they’re developing wouldn’t meet US emissions regs w/o adblue, which is a royal pain in the ass.

    All I can figure is that every time somebody in the USA says “We’re going to offer a Diesel option…” a squad of goons from Sacramento is dispatched within a few days do go decapitate a horse or something. The frequency with which Diesel announcements are later retracted point to this sole logical conclusion.
    It is a wonder that VW, and to a lesser extent Mercedes (and their former proxy Chrysler) have been able to bring any oil-burners to market since the 1990s around here. VW’s thugs must have way more FU than CARB’s.

    They’re from Texas, and their mission is to prevent big-truck owners from ever switching to a more fuel-efficient diesel powertrain.

    Helloooooo……ChryCo?  Real life buyer here.  Love my Wrangler, want a new one, but can’t abide by the horendous fuel economy – makes me feel like a piggy.  Was holding out for one more model year to see if the diesel JK would finally happen.  Thanks for the advance warning – now I can stop waiting and go buy something less cool but more fuel efficient from one of your competitors.

    Amen brothers……one of the main reasons my current ride, xc70, is not a grand Cherokee, previous ride…like my previous 4 jeeps.  This type of management is front and center one of the biggest issues..Ford and GM seem to have seen the light??

    This is asinine, every Jeep should be a diesel.  However, I don’t understand the need for a stop-start diesel.  Gassers I can understand but you can idle a diesel engine for hours on a timbal full of oil [exaggeration for effect].  It seems like a lot of added complexity and expense for insignificant improvements in efficiency (3-5% claimed improvement would be about 1 mpg — and I don’t believe the claim).  Jeep should just focus on getting reliable diesels in their inefficient SUVs and claim the 25%-33% mpg improvement over gasoline before trying to get fancy with stop-start.

    Chuck, did I see you posting on I, Cringely earlier today?

    I see that the 3.8 is going to be replaced by the Pentastar V6. That’s a very good thing. But the Wrangler and the whole Jeep lineup should be getting diesels as well. Oh and that Gladiator pickup thing. If I were Sergio I’d have greelighted that yesterday.

    Diesels that meet USEPA 2010:
    expensive, fussy, and lost a lot of their fuel economy due to emission controls
    if there’s a conspiracy against diesels, it’s in the US govt not the auto companies

      ^ What he said. The cost to make these engines compliant hurts their ability to sell in any volume. Plus, the last two Jeep diesel experiments were hardly a success, and based on that experience, I doubt they are chomping at the bit to try again.

      I’ll also second the “fussy” argument – diesels used to be almost completely indifferent to fuel quality, but thanks to the magic of High Pressure Common Rail fuel systems, they are now super sensitive to overall fuel quality and especially debris. Unless you are filtering out particles down as low as 2-3 microns, you are basically running liquid sandpaper through the injectors.

      You’re obviously plenty knowledgable about this stuff, but I am not buying the conclusion.  VW makes emissions-compliant diesels and still gets major fuel economy advantages vs gas.  It can be done (and should be done).
