2007 Chevrolet Silverado and GMC Sierra HD - Car and Driver
We've run no shortage of coverage of GM's excellent all-new, full-size 2007 Chevrolet Silverado and 2007 GMC Sierra pickups. Until now, though, we've only been able to test the light-duty models, a. k. a. the 1500 series. The myriad advancements in interior and exterior design that we've praised in the 2007 Chevy Silverado and GMC Sierra light-duty pickups have all made it into the new HD versions. The HDs, however, have been beefed up with even sturdier frames, more robust suspensions, and more powerful engines than their light-duty counterparts, or even their 2006-model HD predecessors, for that matter. Both offer bigger grilles, unique bumpers, and taller hoods compared with the light-duty models. As for any significant differentiation between the GMC and Chevrolet versions, well, you're looking at 'em: only exterior styling and an interior trim piece or two. To appease full-size-truck buyers—particularly those in the HD market—it is crucial to offer as diverse an array of configurations as there are uses for each. Consequently, GM offers its HDs with three cab lengths: standard. extended with two rear-hinged, 170-degree-opening rear doors with windows that roll all the way down. Source: www.caranddriver.com
