The GMC Sierra 1500 is like a slightly fancier cousin to the Chevy Silverado. Even though they look different on the outside, they're pretty similar underneath all that shiny metal and paint.

Note that not every options is available depending on the trim or cabin size chosen.
The four engine options available on the 2024 model are a base turbocharged four-cylinder, a strong Duramax diesel, a 5.3-liter V-8, and a bigger 6.2-liter V-8. The Duramax is now standard on the AT4X and the 2.7L will come with a 5yr/100k powertrain warranty.

The Sierra also doesn't disappoint inside the cabin and offers plenty of luxury and a large touchscreen.
GMC largely kept to the existing recipe for the new Sierra 1500. The largest update for the 2024 Sierra 1500 lineup being a small shakeup to the standard powerplants. The 305-horsepower turbocharged 3.0-liter inline-six Duramax diesel engine is now the standard powerplant for the AT4X off-road pickup. Additionally, two fresh wheel choices, new paint options like "Downpour Metallic" and "Thunderstorm Gray," and a new moniker for the 310-horsepower turbocharged 2.7-liter inline-four engine have been introduced - it is now the "TurboMax" engine.
The Sierra offers a versatile range of powerplants, with four different engines to choose from, along with two transmission options, and the availability of rear- or four-wheel drive. The base configuration includes a turbocharged 2.7-liter four-cylinder engine, generating 310 horsepower and 420 pound-feet of torque, coupled with an eight-speed automatic transmission.
For those seeking V-8 power, there are two options available: a 355-horsepower 5.3-liter V-8 and a robust 420-horsepower 6.2-liter V-8. Additionally, a torque-rich diesel six-cylinder engine delivers 460 pound-feet of torque. All three engine choices are paired with a 10-speed automatic transmission. In performance tests, a fully-equipped Denali Ultimate model with the 6.2-liter V-8 engine achieved a 0 to 60 mph time of just 5.4 seconds.
The Sierra 1500 offers flexibility in suspension with the option for adaptive dampers and wheels as large as 22 inches. The rugged AT4 model features a 2.0-inch suspension lift and a suite of genuine off-road equipment. The AT4X shares several attributes with the Silverado ZR2, including advanced spool-valve dampers, electronic-locking front and rear differentials, additional skid plates, and aggressive off-road tires mounted on 18-inch black wheels. For those desiring an even more hardcore off-road experience, an AT4X AEV package is available, incorporating serious off-road accessories such as a steel front bumper with a winch, AEV 18-inch wheels, and robust steel rock sliders.
Towing, Payload, & Fuel Economy
When appropriately configured, the GMC half-ton pickup is capable of towing a maximum of 13,200 pounds and accommodating a payload of up to 2,240 pounds.
With the slew of available powertrain options, the fuel efficiency of the Sierra 1500 will vary. The optional diesel engine can boast ratings of up to 23 mpg in the city and 30 mpg on the highway. The 6.2-liter V-8 engine is estimated to deliver up to 14 mpg in city driving and 17 mpg on the highway when paired with four-wheel drive. Adding 4WD will reduce the fuel economy a little, and opting for the 10-speed transmission will result in slightly improved fuel economy numbers.
