- Exterior colors: Sonoma Red Metallic and Heritage Blue Metallic (not available on Denali)
- Powertrain grade braking in normal transmission mode
GMC Sierra 1500 for 2013 features a broad, diverse and efficient lineup, offering everything from the job-ready Work Truck models to the luxurious Sierra Denali.
Sierra 1500 is available in several trim packages, including Work Truck, SL (crew cab and extended cab), XFE, SLE and SLT, in 2WD and 4WD configurations (XFE is 2WD only). The range of body styles and configurations includes: three cab styles – regular, extended and crew cab – and three cargo box lengths: 5 feet 8 inches (short), 6 feet 6 inches (standard) and 8 feet (long).
A range of powerful yet efficient V-8 engines is offered. Variable valve timing is standard on all V-8 engines and cylinder-deactivating Active Fuel Management is incorporated on 5.3L engines. These technologies help optimize performance and efficiency. In fact, Sierra’s powertrains, backed by fuel-saving, six-speed automatic transmissions, help deliver the industry’s best V-8 fuel economy – including up to 22 mpg on the highway for the Sierra XFE and up to 23 mpg on the highway with the segment-exclusive Sierra Hybrid.
The Sierra XFE is the only full-size truck that offers more than 300 horsepower and greater than 21 mpg on the highway. It incorporates unique aerodynamic enhancements, a 5.3L/six-speed automatic powertrain and other details to deliver its 22-mpg highway rating, while the Sierra Denali fuses performance and unmatched luxury, with specific exterior cues, a well-appointed interior and a powerful 6.2L V-8 engine.
Supported by the robust full-size truck architecture, Sierra’s powertrains also enable excellent capability, including a maximum payload capacity of 1,937 pounds (838 kg). And when equipped with the available max trailering package and the 6.2L V-8, the Sierra 1500 can tow up to 10,700 pounds (4,853 kg).
New for 2013 is powertrain grade braking in the normal transmission mode. It was previously incorporated only when the Tow/Haul mode was activated. It uses engine torque to help slow the vehicle on descents, which helps reduce brake wear. It is featured with the 5.3L and 6.2L engines paired with six-speed transmissions.
Also new is a pair of exterior colors: Sonoma Red Metallic and Heritage Blue Metallic.
Sierra Denali details
The Sierra Denali is offered in 2WD and AWD configurations. It is powered by a 6.2L V-8 engine, rated at 403 horsepower (301 kW) and 417 lb.-ft. of torque (565 Nm). The engine is paired with the Hydra-Matic 6L80 six-speed automatic transmission. Complementing drivetrain features include a 9.5-inch rear axle (2WD) or 8.6-inch rear axle (AWD) with 3.42 gears and an automatic locking rear differential. The specially tuned Z60 suspension, four-wheel disc brakes, StabiliTrak, skid plates and recovery hooks are standard. Twenty-inch chrome-finish aluminum wheels are standard and unique to Denali.
A Denali-specific chrome grille makes the truck instantly recognizable. Additional chrome trim and body-color bumpers further distinguish it. Sierra Denali also offers a unique combination of interior style and luxury, including standard nuance leather-appointed seats, heated and cooled 12-way power-adjustable front seats and an exclusive leather-wrapped and heated steering wheel.
Denali models feature a unique center console, enhanced interior bright work and detailed, highly finished embossed sill plates. The center console has wood grain-appearance trim that conceals the lid and cupholder pockets, creating a more finished and refined appearance.
Sierra design and exterior features
The Sierra lineup is characterized by a rugged yet refined appearance, with chiseled bodywork complemented by details such as chrome bumpers (Sierra Denali features body-color bumpers). Additional elements, including flared rear fenders and premium headlamps, contribute to Sierra’s refinements, while features such as large, grab-style door handles – designed for easy use with work gloves – reinforce the notion that it is a truck first and foremost.
Highlights of Sierra’s standard and available exterior features include:
Sierra’s exterior color choices include Sonoma Metallic, Heritage Blue Metallic, Onyx Black, Mocha Steel Metallic, Stealth Grey Metallic, Steel Grey Metallic, Summit White, Fire Red, Quicksilver Metallic and White Diamond Tricoat.
A wide range of dealer-installed accessories is available for Sierra 1500, including tonneau covers, assist steps, chrome packages, bed liners, utility racks and more.
Sierra interior standard and available features
Sierra features two interiors to meet the diverse needs of customers. The Work Truck, SL and SLE trim levels feature the “pure pickup” interior, while Denali and SLT models feature the luxury-inspired interior similar to GMC’s full-size SUVs.
Work Truck, SL and SLE trim levels feature larger controls and door handles that are easier to use with gloves. A large-capacity, double glove box is part of the instrument panel. Denali and SLT models feature a luxury-inspired interior with a unique instrument panel, door panels, large-capacity center console that offers 20.1 liters of undivided storage and other distinct trim.
A stadium-style rear seat with a 60/40-split design and folding center armrest is standard on crew cab models and available on extended cab models. It can be easily folded up with one hand, without using a release handle, to provide an uninterrupted load floor. Alternatively, either section of the split seat can be stowed independently, allowing room for both cargo and a rear-seat passenger.
Rear access doors on the extended cab open 170 degrees for easy entry to the rear seat/storage area of extended cab models. Power-operated rear side windows lower completely into the 170-degree access doors, providing 100-percent openness on SLE and SLT models.
Additional interior features include:
Sierra models are powered by an efficient lineup of engines, led by Vortec small-block V-8s. Advanced technologies such as Active Fuel Management (AFM) and variable valve timing (VVT) optimize performance and efficiency. Three FlexFuel engines are available and partnered with fuel-saving AFM, giving customers the choice of powering their truck with E85 ethanol, gasoline or a combination of both fuels.
Sierra 1500’s engine offerings include:
Sierra chassis and suspension
Built on GM’s full-size truck platform, the Sierra incorporates features such as a fully boxed frame – with a hydroformed front section – coil-over-shock front suspension and rack-and-pinion steering. Wide front and rear tracks – 68.1 inches (1,732 mm) front/67 inches (1,702 mm) rear – enhance handling and vehicle stability for a more confident road feel, while Sierra’s stiff frame reduces vibrations transmitted to the passenger cabin. The strength and accuracy of the fully boxed frame also enable precise mounting and tuning of chassis and suspension components.
Sierra is offered with five suspension systems, each tailored to suit specific driving requirements:

Standard head curtain side air bags with rollover protection are featured for all seating rows, while standard seat-mounted side-impact air bags for driver and right-front passenger provide thorax and pelvic protection. The roof-mounted head curtain air bags include design features that provide increased rollover protection and occupant containment.
