GMC Sierra

2016 GMC Sierra

The GMC Sierra 1500 line of full-size pickups has been updated for 2016 with the latest technology and revised styling. Distinctive grilles and other visual cues better distinguish the 2016 Sierra models and trim levels from one another.

The GMC Sierra and Chevrolet Silverado share chassis and most mechanicals, and much of what can be said about Sierra can be said of Silverado.

Ruggedly handsome, like a cowboy dressed for the big city, the GMC Sierra looks more conservative and slightly more upscale than does the Chevy Silverado. Sierra Denali models offer real-time damping, a 6.2-liter V6, and an 8-speed automatic.

Among the changes for 2016: revised styling in front, new grille designs, new headlights, LED foglights, new wheel designs. GMs 8-speed automatic is available with the 5.3-liter V8. GMC IntelliLink has been updated with new screens, faster processors, and Apple CarPlay and Android Auto capability. Wireless phone charging is available. A remote locking tailgate is available, as are power-articulating assist steps.

This third-generation Sierra was introduced as a 2014 model.

Getting in and out of a Sierra (or Silverado) somehow seems easier than with some of the other pickups, and loading equipment or sacks of feed in back seems to require a little less heave-ho. The Sierra rides easier and feels more carlike than do most of the others, though Ram rides very well, also.

The GMC Sierra is a comfortable truck. The dash is upright and formal, trimmed with soft-touch material and fitted with buttons and knobs that are easy to operate.

While other manufacturers downsized engines and used turbochargers and lightweight aluminum construction to gain fuel efficiency, GM stuck with larger displacement engines that use direct injection, continuously variable valves, and cylinder deactivation to achieve those goals. A choice of engines is available.

The 4.3-liter V6 is suitable for trucks mostly used for hauling and light towing. The 5.3-liter V8 is rated to tow trailers weighing 11,000 pounds. The 6.2-liter offers more torque and more towing power. Owners who regularly tow trailers weighing more than 10,000 pounds might want to consider a Sierra HD model, however, because stability and braking performance rather than power is often the limiting factor.

The V6 and 5.3-liter V8 come standard with a 6-speed automatic. An 8-speed automatic comes with Sierra Denali, Sierra SLT, and any with the 6.2-liter engine. Four-wheel drive is available.

2015 GMC Sierra

The GMC Sierra delivers stout towing and hauling ability, a quiet cabin, and distinctive styling. GMC Sierra is built on the same platform and shares many mechanical pieces and body panels with the Chevrolet Silverado. Front-end styling and some details vary, but if you ever needed service either dealership could do it.

Sierra was redesigned for the 2014 model, and the 2015 Sierra gets some noteworthy updates. All 2015 Sierra models offer a spray-in bedliner with molded GMC logo, OnStar and 4G LTE with built-in wi-fi, and tow ratings adhere to SAE J2807 standards. New towing mirrors have LED guide lights for reversing, and IntelliLInk adds text messaging alert and Siri eyes free. The 6.2-liter V8 option now comes with an 8-speed automatic transmission. And the 2015 Sierra Denali comes with magnetic ride control.

The GMC Sierra 1500 offers a choice of three cabs and three bed lengths: Regular Cab standard and long bed, Double Cab standard, and Crew Cab standard or short bed. Nearly all offer 2WD or 4WD.

Three engines include a V6 and two V8s, all favoring torque over horsepower and sharing the same fuel-saving technologies often reserved for optional engines. The V6 has the highest torque of any full-size base V6, and the 6.2-liter V8 is the most powerful engine in a light-duty full-size pickup. The smaller engines use a 6-speed automatic and can run E85; the 6.2 uses an 8-speed.

Sierra trim levels vary from work truck with wind-up windows to Denali in stitched perforated leather trimmed with genuine aluminum. Front rows offer seats for two or three, rear seats have three belts, and multiple child-seat anchors, but we dont recommend them for three adults.

Beyond the appearance relative a Silverado, the Sierra offers LED front position lights and Elevation and Carbon Edition specials Silverado does not. Sierra Denali has a unique instrument panel and magnetic ride control not offered on Silverado. Sierra has a higher level of standard equipment. GMCs Pro Grade plan covers some routine maintenance for the first two years or 24,000 miles.

Sierra competes against the Ford F-150, Ram 1500, Nissan Titan, Toyota Tundra and Chevrolet Silverado. If Sierra is too small, try GMC Sierra HD; if its too big, try GMC Canyon.
