2017 GMC Sierra 1500

The 2017 GMC Sierra 1500 has one of the nicest interiors in the class. The quiet cabin has a stylish look, and the quality materials (especially in higher trims) may make you forget that you're in a truck. An easy-to-use infotainment system headlines a lengthy list of available features that also include several driver assistance options.

The Sierra's front seats are large enough for anyone, and they make it easy to find a comfortable seating position. Crew Cab models that feature a rear seat have plenty of room for adults to ride in the back, though the smaller Double Cab's rear quarters may be a bit tight for adults.

• "The instrument panel, central touchscreen, and the array of buttons and knobs are attractive, well-labeled and easy to use." -- Edmunds
• "The GMC Sierra stacks up well against class rivals, and – like its Chevrolet Silverado sibling – offers strong, refined engines, good on-road behavior, plenty of handy in-cabin storage, and an impressively quiet driving environment; top-line models such as the Denali add a healthy dose of luxury to the mix." -- Consumer Guide (2015)
• "It is true that the basic Sierra work truck isn't all that plush, but move up the line to the Denali model and you'll find more leather and chrome than in a Texas rodeo gift shop." -- Kelley Blue Book (2015)

Seating

The Sierra is available with three cab styles. Regular Cab models seat three, and Double and Crew Cab models seat five or six, depending on whether you stick with the standard 40/20/40 split front bench seat or opt for the available front bucket seats. Cloth or vinyl upholstery comes standard. Available seating features include leather upholstery, power-adjustable pedals, power-adjustable front seats, heated and ventilated front seats, and a heated steering wheel.

The Sierra's cabin is quiet, and the front seats are expansive, ensuring that almost anyone will have enough room. You'll also be comfortable thanks to the seats' high degree of adjustability. Double Cab models' rear quarters may feel cramped for adults, but they'll have ample space in Crew Cab models.

The Sierra features two full sets of LATCH connectors for child seats in the rear outboard seats. You can expect to have some trouble installing car seats with this system. For starters, the upper tether anchors can be confused with other hardware. The lower anchors are no picnic, either: they're deep in the seat and hard to access, and a lot of force is required to connect a child seat to them. The Sierra's LATCH system earns a rating of Poor (the lowest rating) from the Insurance Institute for Highway Safety.

• "The Silverado/Sierra's crew cab offers plenty of room and easy access to both rows." -- Edmunds
• "As should be expected in a big truck, the front seats are massive." -- Kelley Blue Book (2015)
• "The seats were comfortable, with a multitude of controls that allow a wide variety of human frames to find their optimal driving position. Acoustically, and this was something we repeated to ourselves several times during our many stints behind the wheel, the Sierra seemed as quiet as a late-model luxury sedan." -- Autoblog (2014)

Interior Features

Standard features in the Sierra include a USB port and a four-speaker audio system with a 4.2-inch display screen. The Teen Driver system also comes standard.

Available features include dual-zone automatic climate control, a power sunroof, Bluetooth, a six-speaker Bose audio system, a rear-seat entertainment system, wireless phone charging, and the voice-activated IntelliLink infotainment system with an 8-inch touch screen, satellite radio, HD Radio, Bluetooth streaming audio, Apple CarPlay, Android Auto, and navigation. OnStar with 4G LTE and a built-in Wi-Fi hot spot is also available.

Available driver assistance features include forward collision alert, forward automatic braking, lane keep assist, a safety alert seat, a rearview camera, and front and rear parking sensors.

The available IntelliLink infotainment system provides you with an easy and intuitive way to control a lot of the Sierra's in-vehicle audio and climate functions. It offers Apple CarPlay and Android Auto, so you should have no trouble syncing your smartphone with the truck. The only drawback to the IntelliLink system is that the voice-control feature can be a hassle if you're trying to use it to control audio or navigation functions.

The infotainment system isn't the only enjoyable feature the Sierra offers. Audiophiles can opt for a Bose sound system. The rear-seat DVD entertainment system, which has two screens, is great for keeping children occupied during road trips.

Trucks aren't known for their driver assistance features, but the Sierra still offers a few. Among them are a rearview camera and front and rear parking sensors, which can help take the guesswork out of parking. There are also features that can help you avoid low-speed crashes, such as forward collision warning and automatic forward braking.

• "We also loved the Sierra's gadgets. Compared to just a few short years ago, it's hard to believe a truck now has USB ports, navigation, in-vehicle apps, wireless cellphone charging and a center-mounted touchscreen. The only gadget we didn't enjoy was the voice-control system, which we had trouble using for both navigation and audio functions." -- Autotrader (2016)
• "We were equally impressed by its five (5!) USB inputs and an AC outlet that can keep a bounty of devices juiced and ready to play." -- Kelley Blue Book (2014)
• "On the subject of cabin likes and dislikes, we praised the bank of USB, cigarette lighter and household outlets at the bottom of the console and the array of gauges on the dashboard that allowed us to monitor just about everything mechanical." -- Autoblog (2014)

Cargo

Regular and Double Cab Sierra models come standard with a 6-foot-6-inch bed, while Crew Cab models come standard with a 5-foot-8-inch bed. Regular Cab models are available with an 8-foot bed, while Crew Cab models are available with the 6-foot-6-inch bed.

The Sierra features a step in the corner of the rear bumper to help you climb into the bed. An EZ-Lift and Lower tailgate is available, which lets you open the tailgate without it slamming and close it without applying much force. In addition to the bed features, the Sierra has several storage spots in the cabin, and the fold-up rear seats lend versatility to those equipped with back seats.

• "A versatile bed, access via bumper steps, a backseat that is easy to manipulate, a flat floor and plenty of small item storage make this a strong utility vehicle." -- Edmunds
• "Steps mounted in the rear bumper along with reworked stake holes make it easy to climb into the bed, while an easy open/close option allows the tailgate to be accessed using just a pair of fingers." -- Left Lane News (2015)
• "Flip-up rear seats offer more cargo versatility." -- Kelley Blue Book (2014)
