The GMC Sierra 1500 V, specifically the Crew Cab Short Box configuration equipped with the 3.0 Duramax Turbo-Diesel engine producing 277 horsepower, represents a notable offering in the full-size pickup truck segment. Introduced as part of the GMTT1XX generation’s facelift in 2022, this variant aimed to strike a balance between capability, fuel efficiency, and refinement for the American truck buyer. It occupied a mid-range position within the Sierra 1500 lineup, positioned between the base gasoline engines and the more powerful 6.2L V8. Production of this specific configuration was limited to the 2022 model year, making it a relatively uncommon find on the used market.

Powertrain & Engine Architecture
The core of this Sierra 1500 variant is the GM LM2 3.0-liter inline-six cylinder Duramax turbo-diesel engine. This engine employs a common-rail direct fuel injection system, delivering fuel at exceptionally high pressures to optimize combustion efficiency. The engine is equipped with a single variable geometry turbocharger (VGT) and an intercooler, both contributing to increased power output and improved efficiency. The DOHC (Double Overhead Camshaft) valvetrain, featuring four valves per cylinder, enhances engine breathing and overall performance. The LM2 engine is recognized for its robust construction and relatively quiet operation compared to some other diesel engines. It’s coupled with a sophisticated 10-speed automatic transmission, offering a wide range of gear ratios for both towing and fuel economy. This transmission is electronically controlled and includes overdrive for efficient highway cruising.
Driving Characteristics
The 277 horsepower and 459.5 lb.-ft. of torque generated by the 3.0L Duramax, in conjunction with the 10-speed automatic, provide a capable and refined driving experience. While not as overtly powerful as the larger gasoline V8 options, the diesel delivers a broad torque curve, making it well-suited for towing and hauling applications. The 10-speed transmission effectively keeps the engine within its optimal power band, resulting in smooth and responsive acceleration. Compared to a Sierra 1500 equipped with a manual transmission, the automatic prioritizes ease of use and convenience, although it may slightly reduce driver engagement. The automatic’s gear ratios are carefully tuned to balance fuel efficiency and towing capacity, offering a practical compromise between the two.
Equipment & Trim Levels
The 3.0L Duramax engine was typically offered within the SLE and AT4 trim levels of the Sierra 1500. Standard features included a user-friendly infotainment system with Apple CarPlay and Android Auto compatibility, a rearview camera, and a comprehensive suite of safety features such as automatic emergency braking. The Crew Cab configuration provides generous space for passengers, while the Short Box offers a practical bed length for everyday tasks. Optional extras included a larger touchscreen display, premium audio systems, leather upholstery, heated and ventilated seats, and advanced driver-assistance technologies like adaptive cruise control and lane-keeping assist.
Chassis & Braking
The Sierra 1500 utilizes a traditional body-on-frame construction, providing a robust platform for demanding tasks. The front suspension consists of independent coil springs, while the rear features a conventional leaf spring setup. This configuration strikes a balance between ride comfort and load-carrying capacity. Braking is handled by ventilated disc brakes on all four wheels, providing ample stopping power. An ABS (Anti-lock Braking System) is standard equipment. The 4WD system enhances traction in various conditions, with selectable drive modes tailored for different terrains.
Market Reception & Comparison
The 3.0L Duramax Sierra 1500 was generally well-received by both automotive critics and consumers. It presented a compelling alternative to traditionally gasoline-powered trucks, offering significantly improved fuel economy without a substantial sacrifice in capability. Compared to the 5.3L V8, the Duramax delivered better fuel economy, particularly during highway driving, but offered slightly less overall power. The Duramax also typically carried a higher initial price tag. In comparison to the 2.7L Turbo, the Duramax provided more torque and towing capacity, but at a correspondingly higher cost.
Legacy
The LM2 Duramax engine has demonstrated itself to be a reliable and durable powertrain. While comprehensive long-term reliability data is still being gathered, initial reports indicate that the engine is performing well in real-world service. On the used car market, the 2022 Sierra 1500 equipped with the 3.0L Duramax often commands a premium over comparable models with gasoline engines, reflecting its fuel efficiency and capability. The combination of diesel power, a comfortable cabin, and advanced technology makes this variant a desirable choice for truck buyers seeking a well-rounded and efficient full-size pickup.
