Figures, now they beef 'em up...

"We expect to see power ratings near or over 400 hp (from the mid-300s), while torque numbers that are typically in the mid- to high-600 lbs-ft range may rise north of 700."
"At the back axle, wider leaf springs with asymmetrical mounting reduce hop and again, carrying capacity goes up—for dual-wheel models, all the way to 9,375 lbs"
"Underneath the familiar Silverado sheetmetal, though, is an all-new truck, starting with a new frame. Make that 11 all-new frames to accommodate variations of cab and cargo box length, 4x4 and rwd drivetrains. The frame is now fully boxed end-to-end and boasts uprated crossmembers to achieve a 92 percent improvement in bending stiffness, a 20 percent gain in torsional rigidity. A new independent front suspension attaches to the hydroformed front segment and this forward portion of the structure is 125 percent stiffer, which let the engineers improve the ride quality and steering feel. Plus, all 4x4 permutations of the HD trucks are now capable of carrying the load of a snow plow thanks to an uprated front axle rating of 6000 lbs."
"and there's an engine braking system that works in conjunction with the new Allison 1000 six-speed transmission to improve performance on steep grades. This latter is a far more sophisticated, electronically managed version of the engine-braking used by 18-wheelers—rather than a manually operated "jake brake" that alters the valve operation to increase engine braking."
Will be released at the 2010 Chicago Auto Show...

"The all-new 2011 Chevrolet Silverado Heavy Duty models might not look all that new and there’s a good reason for it. With tight budgets at GM as of late, the Silverado HD team was given limited funds to build the truck and so they chose to put the money where those who really need a heavy duty truck will appreciate it most. Aesthetically, the only real changes to the 2011 model are a new chrome bumper, a “power-dome” hood and a revised grille. Changes to the rest of the truck, however, are significant."
