With Ford announcing its F-Series Super Duty power, payload and towing capabilities just a few weeks ago, Chevrolet has responded with some big numbers for the all-new 2011 Chevy Silverado HD. The new 6.6-liter Duramax V8 is rated at 397-hp at 3000 rpm and 765 ft-lbs of torque at 1600 rpm. This tops the F-Series Super Duty that’s rated at 390-hp at 2800 rpm and 735 ft-lbs of torque at 1600 rpm. The increase for Chevy is a total of 32-h and 105 ft-lbs over the previous Duramax.
Those numbers don’t tell the whole story, however, as the new truck still follows behind the Ford in payload and towing capability. The new Duramax Silverado HD can tow up to 20,000 lbs and has a payload rating of 6,335 lbs. The F-Series Super Duty is rated at 21,600 lbs and a payload rating of 6,520 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.
As for the new base Vortec 6.0L V8, 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.
