Sierra HDs are ready for the long haul – and the cold.

The details: The 2011 Sierra HDs drive farther without stopping to refuel. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of about 680 miles (1,090 km) with the Duramax 6.6L. Cold-weather customers will appreciate the Duramax 6.6L’s quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment’s best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm the interior more quickly.

The 2011 Sierra HD lineup has the best warranty coverage in America.

The details: All 2011 Sierra 2500HD and 3500HD trucks work under the best warranty coverage in America: a five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that GMC backs its trucks for everything the road offers.
