2025 GMC Sierra 1500 Changes
The 2025 GMC Sierra 1500 receives minor changes to the list of standard features across the line-up, making some trims slightly more expensive while others are slightly less expensive.
Choosing Your 2025 GMC Sierra 1500
The 2025 Sierra 1500 is available in eight trims: Pro, SLE, Elevation, SLT, Denali, AT4, AT4X, and Denali Ultimate. Base Sierra prices range from $39,945 to $87,195, demonstrating that the Sierra can be outfitted to suit the needs of both fleet customers and high-end retail customers.
2025 GMC Sierra 1500 Engine Options
The Sierra 1500 is offered in a range of powertrains, including three gasoline engines: a turbocharged four-cylinder, a V8, a larger V8, and one diesel turbocharged six-cylinder engine. The four-cylinder is fitted with an eight-speed transmission, while all other engines are mated to a 10-speed unit. Rear-wheel drive is standard on most trims except the off-road-oriented AT4 and AT4X trims and the luxurious Denali Ultimate trim, where the automatic part-time four-wheel system is included.
| Trim | Engine Type | Horsepower / Torque | Fuel Economy (Combined) |
| Pro, SLE, Elevation | 2.7L Turbo 4-Cyl 8-speed automatic | 310 hp / 430 lb-ft | 20 MPG (19 MPG 4WD) |
| SLT, Denali | 5.3L V8 10-speed automatic | 355 hp / 383 lb-ft | 18 MPG (17 MPG 4WD) |
| AT4X, Denali Ultimate | 3.0L 6-Cyl Turbodiesel 10-speed automatic | 305 hp | 26 mpg (24 MPG 4WD) |
| Opt. | 6.2L V8 | 420 hp | 17 mpg (4WD only) |
2025 GMC Sierra 1500 Fuel Economy
The four-cylinder gasoline engine returns an EPA-estimated 20 MPG combined, while the V8s return less, as one might expect. The diesel engine easily outpaces the gasoline engines in terms of efficiency; however, the fuel is often more expensive.
It should also be noted that choosing one of the off-road trims or even selecting off-road tires can significantly impact overall fuel efficiency, as their additional capabilities require certain compromises to aerodynamics and rolling resistance performance.
2025 GMC Sierra 1500 Towing Capacity
The Sierra 1500 is rated to haul up to 13,000 pounds with the big V8 engine or the diesel engine. The smaller V8 can manage up to 9,500 pounds, while the four-cylinder is rated for 8,900 pounds. Specific figures vary depending on the drivetrain and cab configurations. Those looking to regularly tow might consider the Sierra 2500 HD and Sierra 3500 HD.
2025 GMC Sierra 1500 Dimensions & Cargo Capacity
The GMC Sierra 1500 can be had in a standard, extended, or crew cab configuration, although not on all trim levels. Most consumers will select the crew cab model and the five-foot bed (a six-foot bed is available on some trims), which is available on all trims. That configuration puts the Sierra 1500 at 232 inches in length, or essentially the same as the Ford F-150 and RAM 1500.
Inside, the crew cab offers a spacious 43 inches of leg room for rear passengers.
Of note, the AT4 and AT4X trims feature a two-inch suspension lift, which raises the overall height to 78.4 inches.
2025 GMC Sierra 1500 Safety
The base Sierra trim includes a basic level of active safety features with automatic emergency braking, a following-distance indicator, lane keep assist, and automatic high beams rounding out the list. Blind-spot detection with rear cross-traffic alert and rear park assist are available through the $740 Safety Plus Package. The SLE’s Safety Plus Package adds an HD surround-view camera system, blind-spot detection with trailer-zone coverage, front parking sensors, and perimeter lighting. The SLE and higher trims also offer auxiliary camera inputs for anyone looking to monitor the inside of the trailer and/ or behind the trailer through the large infotainment display.
GM’s hands-free driving assist system, Super Cruise, is offered in the Denali and Denali Ultimate trims.
2025 GMC Sierra 1500 Technology
The 2025 Sierra 1500 Pro trim has a seven-inch touchscreen, while other trims have a 13.4-inch screen. Apple CarPlay and Android Auto compatibility are standard on all, while the SLE trim adds SiriusXM, remote connectivity, and a Wi-Fi hotspot.
