GM's 2010 2500HD/3500 Trucks
Truck & Duramax Specifications

Pickup trucks and large sport utility vehicles have been GM's most profitable automotive segment. Pickup truck sales accounted for just 1% of the total automotive sales volume in 1959, while trucks (pickups & large SUV's) totaled 64% of GM sales in 2005. Due to their enormous popularity, pickups aren't going away anytime soon, and the Duramax Diesel will remain a big factor in driving pickup sales.

Despite the economic situation, GM's "leaner & greener" product lineup retains most of its former diversity. However, the medium-duty 4500/5500 series commercial truck line has been cut, as well as most of Pontiac and Saturn. Depending on a variety of factors, none the least of which is political, we may see an additional product line shift in the years to come, both in the number of models as well as the type of vehicles offered.

Work began on the 2010 LMM Duramax 6600 more than two years ago. Speculation for most of the past two years included a march toward ever tighter EPA emissions regulations, along with the addition of urea injection. Urea is a form of ammonia, which when injected near the exhaust port of a diesel engine can reduce the creation of nitrogen oxides (NOx), an exhaust component that contributes to the formation of smog. NOx forms when combustion temperatures are highest. NOx and PM (particulate matter in the form of soot) have been two of the toughest emissions components to deal with. Soot has been effectively dealt with by using a DPF (Diesel Particulate Filter) and urea should allow the Duramax 6600 to meet the EPA's future NOx reduction limits. Fortunately, our sources inside DMAX have indicated that the 2010 model year Duramax won't be using urea, but urea is expected to be implemented sometime before the 2012 model year if the current emissions track holds. The Duramax has continually evolved since its introduction in 2000 as a 2001 model year engine, and that trend is continuing. The 2010-2012 model year period will include many incremental changes to the engine block as well as the entire engine package.

Dealer incentives, manufacturer incentives, zero-low interest rate incentives, and dealerships willing to deal have resulted in one of the best times to buy a new GM Duramax diesel equipped pickup truck. TDP

Interesting,,,

I thought that the 2010 (Jan 1st) was the big change in NOX standards. 2007 (Jan 1st) was the big drop in particulates out of the exhaust. Need to due some more searching on the EPA websites to see what the requirement changes are in 2012. It would be good if the could meet the 2010 requirements without the urea.

Also, on the spec sheets above, for the 3500 Weights and Capacities for the WRW Extended Cab / long Box, is there a typo on the 9700 GVWR? I always thought the 3500 SRW always had 9900# rating.

The folks responsible for engine production are not building 2010 engines (at this time) that include the systems necessary for urea. The 2010i (note the "i") models that arrive at dealerships this coming January may include urea - as you mentioned... Good catch. :) GM has been using the "i" denotation since 2007, where the new engines that arrived at the truck plants in January 2007 were destined for trucks equipped with the DPF as well as the new GMT900 sheet metal. The calendar years and model years are out of sync somewhat with regard to EPA emissions certification. So, at least for the remaining months of calendar year 2009, the 2010 models won't be using urea.

It's also a bit tedious predicting what will happen or could happen given the questions surrounding GM's situation. So, I tend to rely more on engine production info.

Sounds like an analogy to the "Classic 2007" Silverado models. They ended production in late December, 2007 (or there abouts).

So we have 1/2 year of production of the current 2009 model, but rebadged a 2010. Then Jan, 2010 we transition to a newer motor that meets the new emission requirements, heck they may even call it a 2011?

Come to think of it, they did the same thing back in 2004 with the advent of the LLY (which appeared in January, 2004). We had 1/2 year of LB7 then 1/2 year of LLY.

The mid-model-year changes are very common. All mfg's do it. The reason is, vehicle model years are introduced mid-calendar-year, and EPA mandates are effected at the beginning of a new calendar year. EPA mandates are usually (if not always), a costly venture, so they put it off as long as possible. Can't say I blame them.
