The recently overhauled 2015 GMC Sierra 1500 delivers some of the best hauling and towing numbers of any light-duty full-size truck while returning better fuel economy and performance. And it boasts enough ports and connections to turn almost any Sierra into a mobile workplace.
For 2014, both the Sierra and its sibling Chevy Silverado received new powertrains, nicer cabins, weightier styling, and a raft of new infotainment and safety features. As a result, they land much closer in our overall ratings to those current benchmarks from Ram and Ford.
The latest Sierra's look is muscular and refined, without straying too much from previous GMC truck design. The 1500 takes cues from the heavy-duty model, including a hood that sits just as high, and a blunt front end with plenty of chrome. The interior features a well laid-out upright dashboard, with easy-to-use controls that can be manipulated even by a gloved hand. Materials are as nice as any in the truck market, with soft-touch plastics used at almost all touchpoints. GMC's signature red lighting is used on the clear gauges as well as for ambient lighting on models so equipped.
The Sierra's styling will be familiar to prior GMC buyers, but now carries a modern flair as well as a muscular look, thanks to its blunt front-end treatment and squared-off, chunky fenders. In most trim levels, we prefer the Sierra's updated styling to the Chevy Silverado's, but that is of course a personal preference, and the decision between the two likely comes down more to content packaging than looks. The Sierra uses LED lighting and projector headlamps to differentiate itself from its Chevrolet sibling on the outside. Either way, it's good if you like your trucks big, because both the GMC and Chevy look like their 2500 and 3500 counterparts, thanks to stylized hoods that sit as high as those on the heavy-duty models.
The Sierra's base engine is a 4.3-liter V-6, but it shouldn't be confused with previous GM truck engines of the same displacement. This one is a credible option for a light-duty truck that will only occasionally tow more than a few thousand pounds. It's quiet, responsive, and relatively smooth for a V-6—it even sounds pretty good, although it doesn't quite match the burble of a V-8. The latest 4.3-liter produces 285 horsepower and 305 lb-ft of torque, which which should make it good for a 0–60-mph time of 8.0 to 8.5 seconds. It's efficient--direct fuel injection and cylinder deactivation are included--returning up to 24 mpg on the highway. The V-6 Sierra is rated to tow up to 7,600 pounds.
The 2015 GMC Sierra 1500 offers a host of cab, bed, and interior options that should satisfy just about any individual's light-duty truck needs. Choosing what's right for you is the hard part.
Regular Cab trucks offer two front-hinged doors and beds either 6'6" or 8' long. Double Cabs all get the 6'6" bed, and in this generation feature front-hinged doors—they no longer require the adjacent front door to be opened in order to gain access to the space behind the front seats. Crew Cabs come with four full-size, front-hinged doors and a choice of either the 5’8” or 6’6” beds. (Previous generations confined Crew Cabs to the shorter, 5'8" bed.)
In terms of access, the longer doors on the Crew Cab make it easy to clamber into the back seats, especially since the Sierra's B-pillars have been moved forward. But since the Double Cab gets front-hinged rear doors, it's almost as capable and accessible.
