Overview
With one major exception, the GMC Sierra 1500 continues largely unchanged into 2024. In service of the long-range and low-end grunt required in overlanding applications, GMC made the 3.0-liter Duramax turbodiesel the standard engine on its off-road-focused AT4X trim Sierra 1500. That engine has also been improved for 2024, and it now makes more horsepower and torque than last year. Otherwise, there are a few minor equipment tweaks with retractable assist steps and active exhaust offered on certain trims.
The Sierra 1500 is available with four engines, two- or four-wheel drive, and a variety of cab and bed combinations across eight trims levels. Like all light-duty trucks the Sierra is designed to serve every possible use case for a light-duty truck. That means it's available in a huge spectrum of versions, starting with a stripped-down Pro trim with 17-inch wheels and a cloth and vinyl interior. The top of the range is the full-luxe Denali Ultimate, which comes with 22-inch wheels, speakers in its tailgate, and available semi-automated driving.
We don't think the Sierra is the best value among light-duty trucks, but it holds its own in most areas. Read our Expert Rating for all the details.
Performance
We're less fond of the Sierra's handling capability. It leans over a lot and generally feels ponderous as you drive around turns. The feel from the steering wheel is also a bit numb. Off-road capability is average for a full-size truck. There's also a Traction Select system, which allows additional wheelspin and smoother initial throttle response in low-traction scenarios.
Comfort
The climate system can easily heat and cool the cabin, but operating it can be a little tricky because a lot of the control buttons are small. We really like the heated split front seats — offering separate settings for the seatback and seat cushion — a GM-exclusive feature. Engine noise is nicely muted until you get hard on the throttle, at which point it becomes a bit unpleasant but not offensive.
Interior
We like the Sierra's latest interior control layout. Knobs, buttons and switches are easy to find and satisfying to press, click or turn. The touchscreen boots up quickly and is responsive to commands. But visibility can be a challenge in full-size trucks, and the Sierra's styling does it no favors. Shorter drivers will have a hard time seeing over the truck's hood, and thick side pillars can also impede your sight lines. It's a good thing an excellent surround-view camera system is available.
Technology
Our test truck came with Apple CarPlay and Android Auto smartphone integration, both with wireless connectivity. CarPlay looked great on the massive screen. There's a dedicated storage space for your smartphone, and some models include a wireless charger. Driver aids are abundant, with several available exterior cameras that help when parking this behemoth of a truck. The rear cross-traffic warning system and its helpful buzzes in the seat bottom are effective too.
Adaptive cruise control generally works well, particularly for such a large vehicle. However, we did experience some aggressive and abrupt braking in our test truck when driving in stop-and-go traffic. GM's hands-free driver assist technology, Super Cruise, is available, but only on the range-topping Denali Ultimate trim. In contrast, Ford offers its similar BlueCruise system on several F-150 trims.
Towing and Storage
Inside, the large center console provides sufficient space for your small items, though it does take up a lot of room between the seats. There are copious cupholders too. Accommodating just about any child safety seat should be easy thanks to the crew cab's massive back seat.
Fuel Economy
Value
GMC's three-year/36,000-mile basic warranty and five-year/60,000-mile powertrain warranty are standard for the segment. Scheduled maintenance (oil changes and tire rotation) is included for the first visit in the first year — Ram and Ford can't match that.
Wildcard
Which Sierra 1500 does Edmunds recommend?
We think the SLE trim offers the best value in the Sierra 1500 lineup. It avoids the pricing problems present in the Sierra's upper trims and still gives you a core set of important features. It comes with cruise control, carpeting, heated seats and the useful MultiPro tailgate.
GMC Sierra 1500 models
Most of the 2024 Sierra 1500's trims carry over without any changes from last year. It is available in eight trim levels: Pro, SLE, Elevation, SLT, AT4, AT4X, Denali and Denali Ultimate. Three cab configurations are offered: regular cab, double cab (it's a crew cab but with smaller rear doors and less rear seat space) and crew cab. Not all trims are available in all configurations. Three bed lengths are available depending on the cab configuration.
The Sierra is available with four engines. They include:
- Turbocharged 2.7-liter four-cylinder engine (310 hp, 430 lb-ft of torque)
- Turbocharged 3.0-liter inline-six diesel engine (305 hp, 495 lb-ft of torque)
- 5.3-liter V8 (355 hp, 383 lb-ft of torque)
- 6.2-liter V8 (420 hp, 460 lb-ft)
Not every engine is available in every trim or configuration. The four-cylinder and 5.3-liter V8 (with rear-wheel drive) come with an eight-speed automatic. There's a 10-speed automatic for the 5.3-liter V8 with four-wheel drive, the diesel six-cylinder and the top-dog 6.2-liter V8. Rear-wheel drive is standard for most trims, with 4WD widely available.
Pro
The entry-level Sierra 1500 is available with either the four-cylinder or 5.3-liter V8 engine. It's about the closest you'll get to a straightforward old-school truck these days. It comes with:

- Wireless charging pad

AT4X
The AT4X is a much more serious off-roader. Besides the AT4's standard diesel engine (6.2-liter V8 remains optional) and all-terrain enhancements, you get plenty of convenience and safety features. Highlights include:

- Carbon-fiber composite bed
- Sunroof
- Head-up display
- 12-speaker Bose premium audio
Many features found in the upper trim levels can be added to the lower trims through option packages. GM's Super Cruise hands-free highway driving system is only available on Denali models, though.
