Special features for 2015

The 2015 GMC Sierra 1500 lineup comprises a set of pickups aimed at a wide range of uses, from personal transportation to purpose-built tow rigs, farm or ranch haulers, or off-road machines. With three cab styles, two bed lengths, three engines, 2-wheel and 4-wheel drive versions, and various trim levels from spartan to lavish, the Sierra lineup offers something for all. Top-of-the-line Denali models remain the choice of more discerning truck shoppers, with luxurious interiors and the full set of features of a premium SUV. The Sierra is a quiet truck, thanks to a host of sound-deadening additions like triple-sealed doors and aerodynamic measures. The Sierra's refined engines are strong yet fuel-efficient. GM boasts that models with the V6 have towing ratings of up to 7,600 pounds, which is hundreds of pounds more than a comparable Ford F-150 or Ram 1500. Also, the Sierra 1500 might have some of the lowest maintenance costs among pickups because of its 4-wheel disc brakes with Duralife rotors, which GM claims will last twice as long as conventional brake rotors.
