GMC’s best-selling vehicle by far is the Sierra, with the light-duty 1500 version accounting for the majority of its sales. This full-size pickup truck is positioned above the Canyon and below the Sierra HD models in GMC’s lineup.
It shares its platform with the Chevrolet Silverado 1500, which is considered a direct competitor. Other rivals in the segment include the Ford F-150 and Ram 1500.
Initially launched in 2019, the current generation of the Sierra 1500 received a significant update in 2022. Last year, GMC introduced the all-electric Sierra EV. The 2025 model is expected to be largely unchanged from the previous year.
Inspired by Ram’s approach, the GMC Sierra 1500 offers a sophisticated and capable take on the full-size truck. GMC provides extensive customization options, including multiple powertrains, cab styles, and bed lengths.
All engine options are robust, and the truck impresses with its driving dynamics, boasting responsive braking, steering, and throttle. The hands-free Super Cruise driving technology continues to win praise for its reliability, and the interior stands out with its high-quality materials and intuitive design.
However, the Sierra 1500 has a few drawbacks. Higher trims can get expensive, and there’s no hybrid option available (though the electric Sierra EV is a worthy alternative). Upgrading to the 22-inch wheels compromises ride comfort, and the Denali’s upscale interior might feel too refined for use as a work truck. Despite these concerns, the Sierra 1500 remains a top-tier choice in its class, with recent updates further enhancing its appeal.
Performance and MPG
The 2025 Sierra 1500 lineup will likely continue offering a range of powertrains, including a turbocharged four-cylinder, two V-8 engines, and a turbocharged inline-six diesel. Both rear-wheel drive (RWD) and four-wheel drive (4WD) configurations are expected to remain available. Fuel efficiency figures should align closely with last year’s models:
- Turbo 2.7L I-4 (TurboMax): 18/22 mpg (city/highway) for RWD
- AT4X 4WD Off-Road Model: 14/16 mpg
Which Sierra 1500 Is Quickest?
For maximum speed, opt for the Denali trim with the 6.2L V-8. A 2022 Sierra 1500 Denali Ultimate managed a 0–60 mph sprint in just 5.7 seconds. However, as electric models like the Sierra EV, Silverado EV, and Ram 1500 REV enter the mix, this ranking could shift.
Cab and Bed Options
The 2025 Sierra 1500 is likely to continue offering:
- Cab Configurations:
- Regular Cab (seats up to three)
- Double Cab and Crew Cab (seats up to six)
- Bed Sizes:
- Short Box (70 inches, crew cab only)
- Standard Box (79 inches, available for all cab styles)
- Long Box (98 inches, regular cab only)
- Safety Ratings and Features
All Sierra 1500 models are expected to include GMC’s Pro Safety suite, featuring:
- Automatic emergency braking with pedestrian detection
- Automatic high-beams
- Lane-keeping assist
- Blind-spot monitoring
Technology
The base 2025 Sierra 1500 is expected to feature:
- Wireless Apple CarPlay and Android Auto compatibility
- High-definition rear camera
- 7.0-inch central touchscreen
Higher trims will offer:
- 13.4-inch touchscreen
- Six-function tailgate
- Automatic locking rear differential
This robust set of features, coupled with excellent performance and customization options, makes the 2025 Sierra 1500 a strong contender in the competitive full-size truck segment.
