2021 GMC Sierra 1500

With its bold styling and elegant lines, the 2021 GMC Sierra 1500 stands out from run-of-the-mill trucks. You can choose from base, SLE, Elevation, SLT, AT4, and Denali trim levels. Depending on the model, the Sierra is available with a regular, double, or crew cab and a short, standard, or long bed. Going with the base trim gets you LED headlamps and daytime running lights, chrome bumpers, 17-inch wheels, cab-mounted cargo lamps, a corner step rear bumper, and LED taillights. The SLE trim offers aluminum wheels, color-keyed door handles, heated mirrors, a power lock and release EZ Lift tailgate, and LED box lighting. Elevation models feature LED fog lamps, color-keyed bumpers, and 20-inch wheels, while the SLT trim has chrome accents, 18-inch wheels, power-folding auto-dimming mirrors, and the class-exclusive six function MultiPro tailgate. Designed for off-roading, the AT4 has exclusive rugged details, raised suspension, 18-inch wheels with all-terrain tires, color-keyed trim, and a spray-in bed liner. The sophisticated Denali features side steps, 20-inch wheels, and a power-sliding rear windshield.

Starting the engine lineup is the base model's 285-horsepower 4.3-liter V-6 that delivers 305 pound-feet of torque. It's matched with a six-speed automatic transmission. Powering the SLE is a 2.7-liter turbocharged four-cylinder engine that generates 310 horsepower and 348 pound-feet of torque via an eight-speed automatic transmission. Other models come standard with a 355-horsepower 5.3-liter V-8 developing 383 pound-feet of torque. Also available are a 3.0-liter inline-six turbo diesel and a 6.2-liter V-8 gas engine, each mated with a 10-speed automatic transmission.

Depending how your truck is configured, the Sierra 1500 offers a towing capacity of up to 11,800 pounds and a maximum payload of 2,170 pounds. The AT4 has a standard all-wheel-drive system that is optional for other models.

The base trim's cab features air conditioning, a 3.5-inch multi-function display, and the GMC infotainment system with smartphone integration, Bluetooth, a 7-inch touch screen, and a six-speaker sound system. Go with the SLE for heated front seats and steering wheel, a power-adjustable driver's seat, a 4.2-inch multi-function display, cruise control, dual-zone automatic temperature control, and a Wi-Fi hot spot. With the SLT, you get driver memory features, a power-adjustable passenger seat, an 8-inch touch screen, and two 120-volt power outlets. The range-topping Denali features ventilated front seats, heated second-row seats, an 8-inch digital instrument display, navigation, and a Bose audio system.

The Sierra comes standard with electronic stability control, traction control, a rear seat reminder, tire pressure monitoring, and a rearview camera. Available driver-assist technology includes lane-keeping assist, lane departure warning, lane change alert, blind-spot monitoring, a following distance indicator, forward-collision warning, front pedestrian braking, and rear cross-traffic warning. An available ProGrade Trailering System makes it easier to hitch and tow a trailer.
