GMC Sierra 2500HD SLE Review - GMC Sierra 2500HD is Though "HD" has become a familiar pop-culture concept in recent years, rest assured that the HD part of GMC Sierra 2500HD does not, in fact, involve plasma or LCD TVs. In this case we're talking the old-fashioned meaning of HD: "Heavy Duty." As one of two GMC heavy-duty full-size pickups, the 2500HD is a true workhorse meant for big-league power, towing and hauling capabilities.
Current GMC Sierra 2500HD: The GMC Sierra 2500HD is available in regular-, extended- or crew-cab designs, with a long or short wheelbase, and with rear- or four-wheel drive. The extended- and crew-cab body styles are offered in four trim levels: Work Truck, SLE1, SLE2 and top-line SLT. The regular cabin can only be had in Work Truck and SLE1 trims.
Standard on all Sierra 2500HD pickups is a 6.0-liter V8 that makes 360 horsepower and 380 pound-feet of torque, paired to a six-speed automatic transmission. The burly Duramax 6.6-liter turbodiesel V8 that puts out 365 hp and 660 lb-ft of torque is optional. Its standard Allison six-speed automatic is well suited to towing and hauling large loads.
