GMC has decided that they will acknowledge the age old saying of "bigger is better" by adding jumbo-sized versions of the already popular Denali HD 2500 series. GMC announced today that the Sierra HD Denali will become available in Denali HD crew cab versions of the 3500 Series (1-ton) for both single rear wheel and dually versions in 2WD and 4WD applications - next to the current 2500 series (3/4 ton), crew cab and 4WD version. Following the success of the 2500 series, additional versions simply had to be created in order to take advantage of the popularity the truck currently has.
The Sierra HD Denali is powered by a Vortec 6.0L gas V-8/six-speed automatic powertrain. For a little more of the green paper, GMC can also provide a new Duramax 6.6 liter turbo diesel V-8 delivering a total of 397 hp at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm. The 0-60 mph sprint will be made in less than 9 seconds and quarter-mile in less than 16 seconds in 2500HD models. The engine is mated to a new Allison 1000 six-speed automatic transmission.
