After unveiling the new 2011 Silverado HD at the Chicago Auto Show earlier this year, Chevy has now released pricing for the big truck. Standard models will start 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.

The new base Vortec 6.0L V8 makes 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. As for the new 6.6-liter Duramax V8, it is rated at 397-hp at 3000 rpm and 765 ft-lbs of torque at 1600 rpm. The increase for Chevy is a total of 32-hp and 105 ft-lbs over the previous Duramax. As a result it can tow up to 20,000 lbs and has a payload rating of 6,335 lbs. GM is proud to boast that fuel economy with the new engine has been increased by 11 percent (although not mpg numbers are available), with a total driving distance of 680 miles on a tank.

In addition to the fuel economy improvements, Chevy 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.

A new front suspension with forged steel upper control arms and cast iron lower control arms is also a part of the 2011 package 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. Chevy also says that under heavy load it has reduced noise vibration and harshness (NVH) by as much as 30 percent.
