The 2014 GMC Sierra 1500 is a full-size, light-duty pickup truck offered in regular, extended, and crew cab body styles. It is completely redesigned for 2014, equipped with a choice between three new engines, and offered with several options that are new to the Sierra lineup.

"Our engineers and designers left nothing on the table when developing this latest Sierra pickup," said Tony DiSalle, vice president of GMC Marketing. "These trucks have all the power and capability that's expected in today's market, excellent fuel efficiency, plus a lot of unexpected, purposeful features developed with truck owners in mind."

The 2014 Sierra Crew Cab goes on sale in the spring of 2013, with regular- and extended-cab models following shortly thereafter.

Exterior Features

Although the new 2014 GMC Sierra shares many components with its corporate sibling, the 2014 Chevy Silverado, it offers unique design elements combined with additional standard equipment.

Front styling is unique to the Sierra, which comes standard with projector-beam headlights, chrome grille, and black wheel arch moldings. As an option, LED running lights are available for the new 2014 Sierra. The Sierra also includes standard adjustable cargo box tie-down cleats and offers unique wheel designs ranging from 17 inches to 20 inches in diameter. Low-rolling-resistance tires are standard, and are designed to incrementally improve gas mileage.

The new 2014 Sierra is more aerodynamic than the model it replaces, adding front sealing, cab-to-bed seals, underbody panels, and aerodynamic spats forward of the wheels to help the truck slip through the atmosphere with less resistance. The side mirrors are aerodynamically designed, and the truck is equipped with subtle spoilers on the edge of the roof and on the tailgate. Even the hood is shaped to reduce aerodynamic drag over the windshield wiper arms, according to GMC.

The new Sierra's side doors are an "inlaid" design, meaning they're set into the body and don't wrap into the roof. This is a more aerodynamic solution and also helps to reduce noise inside the truck's cab, the company says. Around back, just as with the Silverado, the 2014 Sierra is equipped with corner steps integrated into the rear bumper and hand-holds integrated into the box rail protectors.

Cargo box lengths measure 5'8", 6'6", and 8.' The former two are offered for the Sierra Crew Cab, and the latter two are offered for the Sierra Regular Cab. The Sierra Extended Cab is equipped only with the 6'6" box.

Interior Features

GMC says the 2014 Sierra offers a quieter, roomier and more functional interior than the previous model. Standard equipment includes a 6-gauge instrument cluster, and most Sierras will also have a 4.2-inch color information display nestled between the gauges. Dual glove boxes, several USB ports, and both 12-volt and 110-volt power outlets are included for all Sierras.

Soft-touch cabin materials provide improved look and feel, while the seats are equipped with new dual-density foam for improved comfort. Buyers choosing cloth seats get new stain-resistant, high-wear fabric designed to bead liquid rather than allow it to soak into the fibers.

GMC designed the new Sierra's interior controls to be easily operated by someone wearing work gloves. The company says that all knobs employ rubber-over-mold technology to make them easy to grip. An 8-inch color touch-screen display is offered on higher trim levels.

Sierra Crew Cab models offer an additional 2 inches of rear leg room compared to last year, and the rear doors on this model are longer to make it easier to get into and out of the truck. Extended-cab models get new forward-hinged rear access doors for the same reason.

Optional Features

The 2014 Sierra SLE and Sierra SLT trim levels can be equipped with an All-Terrain package that includes off-road suspension tuning with Rancho monotube shocks, a transfer case skid plate, automatic-locking rear differential, and 18- or 20-inch aluminum wheels equipped with all-terrain tires. The Sierra All-Terrain also includes a hill-descent control system, front tow hooks, painted grille, reduced exterior chrome, brushed metal doorsill plates, and unique interior trim.

Additional options for the new Sierra include an EZ Lift and Lower tailgate, under-rail LED bed lighting system, integrated trailer brake controller, and dealer-installed 22-inch aluminum wheels. Leather, heated seats, navigation, IntelliLink technology, and genuine aluminum cabin trim are also offered on this trim level.

Under the Hood

The new 2014 Sierra 1500 is offered with a choice of a 4.3-liter V-6, 5.3-liter V-8, or a 6.2-liter V-8 engine, all equipped with direct fuel injection, variable valve timing, and GM's proprietary Active Fuel Management technology that shuts off half of the engine's cylinders under low-load driving conditions to conserve fuel.

Perhaps in reference to the 2013 Ram 1500's new 3.6-liter V-6 engine, Jordan Lee, powertrain chief engineer for the new Sierra, said: "Rather than adapting a V-6 intended for use in passenger cars, we built a new engine from the ground up based on the unique demands of a truck. Sierra's 4.3-liter V-6 shares its basic design architecture with the latest iterations of the V-8 engines that GMC owners have trusted for generations."

All three of the Sierra's new engines develop more horsepower and more torque than the engines they replace, and are more fuel efficient. Final power, payload and tow ratings will be available when the new Sierra debuts at the Detroit Auto Show in January 2013.

A 6-speed automatic transmission is standard, and includes a new Cruise Grade Braking feature. Electric steering, new DuraLife brake rotors, and a stiffer suspension with aluminum upper and lower front control arms are also included on the 2014 Sierra.


Every 2014 GMC Sierra is equipped with 4-wheel-disc anti-lock brakes, traction and stability control system with trailer sway control, hill-start assist, and OnStar telematics with a limited-time subscription to Automatic Crash Notification service.

Optional safety features include a forward-collision alert system, lane-departure warning system, Active Safety Seat system, front and rear park-assist sensors, reversing camera, and side mirrors equipped with glass that allows the driver to see in the truck's blind spots.


The 2014 Sierra is offered with optional IntelliLink technology, which can be paired with up to 10 different devices. Natural voice-recognition technology allows for hands-free operation, and the high-definition, reconfigurable 8-inch color touch screen offers up to 60 pre-set favorites. Pandora Internet radio and an SC card slot are included with IntelliLink.
