First Drive: 2011 GMC Sierra and Chevrolet Silverado Heavy Duty technical deep dive

Filed under: Truck, Marketing/Advertising, Technology, Work, Chevrolet, GM, Diesel

At first glance, the 2011 Chevrolet Silverado and GMC Sierra heavy-duty pickup trucks don’t appear to have changed much compared to their 2010 counterparts. But don’t let their familiar faces fool you, because virtually all of the greasy bits have been substantially upgraded or replaced entirely. Like the competitive heavy-duty trucks from Ford and Dodge, General Motors offers its trucks in a huge array of configurations with varying passenger, payload and towing capacities and an array of gasoline and diesel engines.

We drove seven different variants over two days in the Allegheny mountains of western Maryland along with the latest models from Dodge and Ford for comparison’s sake. While the sales volume in the heavy-duty truck segment is smaller than it was at its peak a few years ago, it is still hugely profitable and comprises about 25 to 30 percent of all pickup sales.
