Product Information


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.

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.

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 has a strong body structure to absorb crash energy and provide a protective “safety cage” around occupants. 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.

Additional safety features include:
