2025 GMC Sierra 1500

The GMC Sierra 1500 is legendary for its light-duty capability, rugged reliability, and elevated features, making it one of America’s favorite full-size trucks for over three decades. The 2025 GMC Sierra 1500 continues the brand’s reputation for excellence, with multiple engine options, impressive payload and towing capability, and innovative technology.

Four Versatile Powertrain Options

With four versatile powertrain options available, the Sierra 1500 can be tailored to the needs of the driver. The standard engine is the efficient TurboMax, which is paired with an 8-speed electronically controlled automatic transmission with overdrive and dedicated tow/haul mode. The powertrain produces 310 horsepower and 430 foot-pounds of torque and has an estimated fuel efficiency of 17 MPG in the city and 19 MPG on the highway.

There’s an available 5.3-liter EcoTec3 V8 that creates 355 horsepower and 383 foot-pounds of torque, as well as a 6.2-liter EcoTec3 V8 that makes 420 horsepower and 460 foot-pounds of torque. There’s even a diesel option in the 3.0-liter Duramax turbo diesel, which delivers 305 horsepower and 495 foot-pounds of torque. The three larger engines are paired with a 10-speed automatic transmission, and Sierras are available in RWD or 4WD.

Hard-Working Payload and Towing Power

The Sierra 1500 is considered a light-duty half-ton pickup, but it has the payload and towing capability to tackle tough tasks. Crew cab versions of the Sierra 1500 can transport up to six adults comfortably, and the standard 6.5-foot cargo box has a volume of 71.7 cubic feet and a maximum payload capacity of 2,530 pounds when properly equipped.

For loads that outweight the cargo bed capacity, the Sierra 1500 has impressive towing capability. It’s rated for a maximum towing capacity of 13,300 pounds, depending on the powertrain choice and optional equipment selection. With trailering amenities such as hitch guidance, outside power-adjustable vertical trailering mirrors, hitch view camera, in-vehicle trailering app, and integrated trailer brake controller, towing tasks are greatly simplified.

Innovative Safety and Infotainment Tech 

The safety and infotainment technology in the Sierra 1500 helps drivers and passengers arrive safely while maintaining connectivity. The Sierra 1500 has a 5-star overall safety rating from the National Highway Traffic Safety Administration, partly due to standard features such as a forward collision alert, automatic emergency braking, six airbags, a following distance indicator, rear cross traffic braking, and lane keep assist with lane departure warning.

Standard connectivity and infotainment technology in the Sierra 1500 includes a 6-speaker audio system, wireless Apple CarPlay and Android Auto connectivity, a 13.4-inch multi-color reconfigurable infotainment display, Wi-Fi hotspot capability, and a 3.5-inch driver information center.
