GMC has just released pricing for its new line of 2011 Sierra HD models, starting from $27,965, while those wanting the Duramax diesel and Allison transmission combo will have to spend $36,360 – a jump of $8,395. That price is, however, the exact same number as last year’s model, which is impressive considering the improvements made for the all-new 2011 truck. As for the new Sierra Denali HD (a 2500HD 4WD crew cab), it’s set at $45,865.
With an all-new frame, the 2011 Sierra comes standard with a 6.0-liter Vortec V8 and six-speed 6L90 automatic transmission. It gets 360-hp at 5400 rpm and 380 ft-lbs of torque at 4200 rpm. A total of 90 percent of the engines torque is available from 2000 rpm allowing for a 13 percent increase in fifth-wheel towing for a total tow rating of 14,700 lbs.
Diesel models get a new 6.6-liter Duamax engine and 6-speed Allison transmission with a best-in-class power of 397-hp at 3000 rpm and best-in-class torque of 765 ft-lbs at 1600 rpm. The engine block itself is a carry-over from the past model but the majority of moving engine parts are new, as is the entire fuel system. NOx emissions are also down 63 percent thanks in part to an exhaust after treatment system that is used because it won’t interfere with the engine’s ability to create power. The Diesel Exhaust Fluid (DEF) used in the process does require refilling every 5,000 miles. In addition, the new engine is B20 biodiesel capable.
As for the new Allison transmission it has been strengthened to work with the added torque of the new engine and features an optional exhaust brake, Power Take Off and a Driver Shift Control (DSC). It’s also designed to work with the new Duramax engine to give improved fuel economy by 11 percent and GMC says to expect a fuel range of 680 miles on the new 36 gallon tank.
In addition to the fuel economy improvements, GMC claims improved acceleration with Duramax/Allison combo, resulting in a 0.3-second improvement to 60 mph and a 0.5-second improvement in the quarter-mile for a rating of less than 9 and less than 16 seconds respectively.
Like it’s Chevy counterpart, the Sierra gets a new front suspension with forged steel upper control arms and cast iron lower control arms with the new front independent suspension now delivering a 25 percent improved front axle weight rating. The new 6,000 lb rating now means a snow plow can be used on all 4WD cab models equipped with the snow plow prep package. In addition, rather than a single torsion bar like on the previous model, the 2011 gets five different torsion bar rates for five different gross axle weight ratings, allowing height adjustability in accordance with the weight of a snow plow or other accessory.
As for the rear suspension, the leaf springs are now 20 percent wider, helping to improve the truck’s rear gross axle weight rating. Now 2500 models are rated to 6,200 lbs, while 3500 models get a 7,050 rating for single wheel or 9,375 of dualies. The new rear suspension is also designed to reduce wheel hop.
Safety equipment includes StabiliTrak and Trailer Sway Control on all single-rear-wheel models as well as a new Hill Start Assist feature, that holds the truck for 1.5 seconds when leaving a stop on a hill. GMC also says that under heavy load it has reduced noise vibration and harshness (NVH) by as much as 30 percent.
All Sierra HD models will be built at GM’s Flint Assembly Plant, with retails sales beginning in June.
