According to our friends over at PickupTrucks.com, Chevrolet will show off the latest iteration of its Heavy Duty pickup truck at the Chicago Auto Show next month. The 2011 Chevy Silverado 2500 and 3500 (2010 model shown above) are expected to be equipped with a new version of the well-regarded 6.6-liter Duramax diesel V8 engine that will almost assuredly use a urea solution to curb nitrogen oxide emissions. General Motors continues to partner with the diesel experts at Isuzu for the Duramax engine.

Under what's sure to be somewhat revised sheetmetal will reportedly be an all-new chassis along with some "other surprises," surmises PickupTrucks.com. We expect a GMC Sierra HD to also be on display, but we can't say for sure. We'll be on hand in Chicago to see how GM reacts to the 2011 Ford Super Duty pickups and their all-new 6.7-liter diesel V8 engine, so stay tuned.
