IntroductionThe Sierra is GMC's basic light-duty, full-size work truck. With the exception of some luxury and styling features that set it apart, it is equivalent to the Chevrolet Silverado. The Sierra and the Silverado have the same base price, but the Sierra price is slightly higher with all options included. The GMC Sierra competes with the Ford F-150, the Ram 1500, and the Toyota Tundra, among others. GMC has been producing work trucks since 1930, employing the Sierra name as a trim level until adopting it as the standard GMC truck badge in 1987. The Sierra 1500 is available with several conventional engines and in a hybrid version.
Exterior FeaturesIn anticipation of an extensive redesign for 2014, the Sierra 1500 is little changed for the 2013 model year. The 1500 is available with a regular, Extended, or Crew Cab. Payload and towing capacities, depending on engine type and additional towing equipment, can go as high as 1,940 lbs. and 14,000 lbs., respectively. An Off-Road Package is also available. The Sierra 1500 is available in five trim levels: Work Truck (WT), SLE, SL, SLT, and XFE. The base trim features a black front bumper and grille, 17-inch steel wheels, tailgate protection, black door handles and chrome rear step bumper. The SLE adds a heavy-duty Handling/Trailering Suspension Package, upgraded chrome grille, body-colored side moldings, upgraded mirrors, and more. The SLT adds a heavy-duty automatic locking rear differential, a heavy-duty cooling package, and much more. The Sierra 1500 is available with rear-wheel or 4-wheel drive.
Interior FeaturesThe WT trim offers vinyl seats, AM/FM radio, daytime running lamps, manual air conditioner, and cruise control. The SLE trim upgrades to cloth seating and adds a leather-wrapped steering wheel, adjustable seating, power windows and locks, a stereo with CD player, speakers, driver-side seat adjuster, and more power features. The SLT trim adds an auto-dimming inside rearview mirror, fog lamps, remote vehicle starter system, rear-window defogger, power, and heated outside mirrors with integrated turn signal indicators. Interior amenities on the SLT include automatic dual-zone climate control and power and heated leather-appointed front bucket seats.
Optional FeaturesMany option packages are available at the various trim levels. The WT offers the Preferred and Work Truck Plus packages, which add power features, chrome, fog lamps, and other features. A wide selection of tonneau covers, hard and soft, is also available. Additional options are offered at various trim levels. The SLT offers the Max Trailering Package, the All-Terrain Package, two dealer-installed chrome packages, an integrated trailer brake controller, and much more.

TechnologyA Tow/Haul Mode modifies the automatic transmission shift schedule for heavy-duty pulling and hauling. Auto-grade braking helps control the vehicle on steep downgrades and saves wear on the braking system, and an integrated trailer brake controller is available. OnStar with vehicle diagnostics is standard for a 6-month trial period. OnStar automatically runs hundreds of diagnostic and maintenance checks and sends results via email. A mobile app permits remote start and temperature adjustment, locking and unlocking, and much more through your mobile phone.
