Just as we go and declare the 2011 Ford Super Duty the best heavy-duty pickup on the market, GM comes along and crushes Ford's power figures. The new Chevy Silverado HD diesel makes a staggering 765lb-ft of torque and 397HP.
GM tossed all of the 2011 Silverado HD development money into the guts of the truck — new frame, reworked rear suspension, transmission and a thoroughly reworked Duramax engine. The result is a work truck with some very impressive numbers: Power is up from 365 HP to 397 HP at 3000 RPM and torque is up from 660 lb-ft to an astonishing 765 lb-ft at 1600 RPM.
For reference that's only 7 HP more than the 2011 Super Duty's Powerstroke, but a 30 lb-ft advantage in torque. In addition to increased the power GM's claiming an 11% improvement in fuel economy while reducing emissions with a NOx catalyst and particulate filter. It seems the truck wars have just gotten very, very serious.
