2015 GMC Sierra 2500 / 3500 HD - Car and Driver
The all-new Sierra 2500 HD shares its chassis with the Chevy Silverado HD but wears Prada instead of work boots. It offers the same three cab styles, five wheelbases, two bed lengths, and three engines: 6. 0- and 6. 0-liter gas/CNG V-8s and our favorite, the Duramax 6. 6-liter turbo-diesel with the Allison transmission. First Drive Review – 2015 GMC Sierra 2500 / 3500 HD Big-City Fixin’s. The Sierra HD’s industrial-chic styling works well with its blocky silhouette, with additional brightwork and details versus the Silverado, such as plastic trim guarding the wheel arches. GMC says one of every four HD truck buyers opts for the chromed-out Denali trim , which has received additional touches inside and out to further assert its top-dog status. Double-cab Sierras (and Silverados) now have proper front-hinged rear doors for simpler rear-seat access, and crew-cab models gain larger rear openings and slightly more room in which to stretch out. And because the double cab now has a proper B-pillar, cab stiffness is improved, resulting in far fewer squeaks and shakes over rough terrain than with last year’s rear-hinged extended-cab models.
