The Chevy Silverado Hybrid, also slated for a 2009 release, will join it and the two essentially function identically.  However the GMC Sierra Hybrid will cost a little more due to its description as a professional grade truck.  It features the same hybrid technology as other hybrid SUVs.  It has an engine that will shut down half of its cylinders while cruising and shutting down completely when the truck comes to a stop.  The addition of the electric motors dictates that the only available transmission is a four four-speed automatic.

Unlike the regular gas powered model the GMC Sierra Hybrid is also available only in a four-door crew cab with a short cargo bed.  This is the most passenger-friendly and should be able to easily accommodate 5-6 people.  The seating accommodations more closely resemble that of an SUV instead of a pickup truck.  In addition to the seating style, the other cab amenities make the GMC Sierra Hybrid more suited toward hauling passengers than cargo, although it can do both.

Their towing and hauling capacity make most pickups reputations, and the GMC Sierra Hybrid is no different.  It has a maximum towing ability of 6,100 pounds with rear wheel drive and slightly less with the four-wheel drive.  This is more than sufficient to two a medium sized trailer and cargo.  This is significantly less than the regular gas powered model.  The GMC Sierra Hybrid is certainly not a leading authority in this arena, but it is capable of handling the average towing need.

If you need a large and powerful truck, and want to pay a higher price then you may have found the right hybrid for you.  However if you need a large cargo bed, or do not want to pay the higher starting price, the GMC Sierra Hybrid might not be for you.  Ultimately the truck’s limitations are compensated for the better fuel economy and savings at the gas pump.
