2023 GMC Sierra 1500 Full Details Information
Full-size pickups are the top three bestselling vehicles in the U.S., and the GMC Sierra 1500 repurposes the guts of its mechanical twin, the Chevy Silverado, in an attempt to compete in the upscale side of the segment. Its massive configurability is your friend. The Sierra 1500 is available as a single cab, double cab, or four-door crew cab with beds ranging from 5.8-to-8.2 feet in length. Engine options include a 310-hp turbo four-cylinder, a Duramax turbodiesel with 460 pound-feet of torque, a 355-hp 5.3-liter V-8, and a 420-hp 6.2-liter V-8 with as much torque as the oil burner. The Sierra 1500 has the third-highest conventional towing capacity of all half-ton pickups with a max rating of 13,200 pounds. Go ahead, tow that 747. While the Sierra’s available 13.4-inch touchscreen is impressive, the rest of its interior, unfortunately, doesn’t match the richer feel of the top-spec Ram 1500’s cabin in terms of materials or quality of assembly. 2023 GMC Sierra 1500
Engine, Transmission, and Performance
The Sierra is available with four different engines, two different transmissions, and rear- or all-wheel drive. The base setup is a turbocharged 2.7-liter four-cylinder that makes 310 horsepower and 420 pound-feet of torque. It pairs with an eight-speed automatic transmission. There are two V-8 options: a 355-hp 5.3-liter and a 420-hp 6.2-liter. A torque-rich diesel six-cylinder generates 460 pound-feet. All three engines hook up to a 10-speed automatic. At our test track, a loaded Denali Ultimate model with the 6.2-liter V-8 hit 60 mph in just 5.4 seconds. The Sierra 1500 also can be had with adaptive dampers and wheels as large as 22 inches. While the Sierra lacks the extreme off-road abilities of the high-flying Ford F-150 Raptor, it does offer two dedicated off-road variants. The rugged AT4 model boasts a 2.0-inch suspension lift and other legitimate equipment. The AT4X shares exclusive features with the Silverado ZR2, including advanced spool-valve dampers, electronic-locking front and rear diffs, extra skid plates, and gnarly off-road tires mounted on black 18-inch wheels. An AT4X AEV package adds even more serious off-road accessories, like a steel front bumper with a winch, AEV 18-inch wheels, and steel rock sliders Sierra has a rougher ride than the Ram 1500, but it still handles remarkably well thanks to responsive steering and restrained body roll.

Towing and Payload Capacity
The half-ton GMC pickup can tow up to 13,200 pounds and support a payload up to 2240 pounds, when properly equipped.
Fuel Economy and Real-World MPG
The Sierra 1500 has several different powertrain combinations, which means its fuel-economy ratings vary. Those most concerned with fuel efficiency should entertain the optional diesel engine, which is rated up to 23 mpg city and 30 mpg highway. However, most Sierras will be packing the 6.2-liter V-8 that comes standard with every Denali model. It’s estimated to earn up to 15 mpg city and 20 mpg highway when paired with all-wheel drive. The GMC Sierra 1500 Denali we tested achieved 18 mpg in our real-world highway test. For more information about the Sierra’s fuel economy, visit the EPA’s website.
Interior, Comfort, and Cargo
Inside, the Sierra is designed with the driver in mind. The controls are all easy to reach and the quality of the materials generally increases with the trim levels. Starting on the SLE, a 12.3-inch digital instrument panel becomes standard. Spending big on the upper trims unlocks even more desirable features, including a heads-up display and a power-adjustable steering column. The Denali Ultimate is where things get seriously upscale thanks to open-pore wood trim and a surplus of leather-covered surfaces. The front seats also feature 16-way power adjustments as well as massage functions. Interior cubby storage is more than adequate for storing all manner of small items and stuff. While GMC doesn’t offer any particularly innovative storage features, the Sierra 1500 can be had with a trick tailgate that has multiple configurations. There’s also a class-exclusive carbon-fiber-reinforced cargo bed that is lighter and supposedly stronger than steel. GMC Sierra
Infotainment and Connectivity
Most Sierra 1500s feature a 13.4-inch touchscreen through which the truck’s infotainment system runs. This larger screen includes wireless Apple CarPlay and Android Auto as standard. It also has built-in Google software that allows users to access an app store, maps, and a voice assistant. Other available features include a 12-speaker Bose audio system, wireless phone charging, and additional power points. GMC Sierra
