    Arrow 2011 Trucks - February Update

    2011 Chevrolet 2500HD/3500 Trucks
    This past February 4th, and we learned all about GM's plans for the 2011 model year GM 2500HD/3500 series pickups. Though we're expecting a price increase of $3,000-$5,000, due to the addition of the "Diesel Exhaust Fluid" (urea) system, GM is back with a range of improvements and upgrades that promise to make GM the HD diesel truck leader. Go here for all of the new truck details.

    Engine & Emissions Tech
    The 2010 emissions regulations are upon us - as well as GM. Here's an indepth look at the new 2011 LML Duramax 6600 and emissions equipment. How's it all work? What effect will it have on ownership? What else is new & different about the Duramax? We'll answer all these questions and more.

    Reading about the urea injection and system and the Diesel Exhaust Fluid......the first thing that comes to mind: "Is this some kind of joke?"

    I'm reminded of Muffler Bearings and Blinker Fluid. Most people will react the same way when they hear of Diesel Exhaust Fluid.

    Man oh man, I'm sure glad the government isn't controlling every aspect of our lives!!!! (limiting speed until you refill the DEF tank)

    When compared to the outgoing 2010 models, GM is hoping the increased GVWR/GCVWR, increased braking power, stronger frames, smoother ride, Stabilitrak/anti-sway control, exhaust brake, 20" wheels, more luxurious interiors, improved fuel economy and more will help compensate for the tedium and added cost of the 2011 model-year DEF system. They are sweet trucks.... Muffler bearings and blinker fluid are optional...

    Do you know if Ford and Dodge will be installing similar systems? I haven't studied much on the competition lately.

    If I remember correctly, Ford's new Scorpian diesel will use DEF, but the Dodge diesel light-trucks might not. Curiously, the Dodge medium-duty Cummins-equipped trucks are supposed to be using DEF.

    It's a tough call to know how it'll all turn out...

    I'm for re-evaluating the EPA's diesel emissions regulations - in light of the economy and the reduced on-road use of diesel fuel, and the 90+% percent improvement in diesel emissions since 1990.

    You're right:

    Ford - urea req'd for F250 on up
    Ram - no urea req'd for 3/4 & 1 ton pickups IIRC. They're using some other kind of aftertreatment for NOx. Chassis cabs use urea.

    In the heavy duty truck world, Navistar is the lone ranger opting for gobs of EGR. I believe everybody else is using SCR (the emissions device that requires urea).

    Looks like a very serious truck!

    I'm just not very excited about the SCR system.
