The GMC Yukon XL V, specifically the facelifted 2024 model equipped with the 3.0 Duramax turbodiesel engine producing 305 horsepower and paired with a 10-speed automatic transmission, represents a significant offering in the full-size SUV segment. Introduced as part of the fifth-generation Yukon XL (introduced in 2021, with the 2024 model receiving a substantial refresh), this variant caters to buyers seeking a blend of substantial space, towing capability, and improved fuel efficiency compared to gasoline-powered counterparts. The Yukon XL V slots into the Yukon XL lineup as a premium option, positioned above the base trims but below the fully-loaded Denali models. It directly addresses a demand for diesel power in large SUVs, particularly for those frequently engaged in towing or long-distance travel.

Powertrain & Engine Architecture
The heart of the Yukon XL V is the LZ0 3.0-liter inline-six cylinder Duramax turbodiesel engine. This engine utilizes a common-rail direct fuel injection system, delivering fuel at extremely high pressures for optimized combustion. The engine also features a variable geometry turbocharger (VGT) and an intercooler to enhance power and efficiency. The DOHC (Double Overhead Camshaft) valvetrain contributes to improved engine breathing and responsiveness. A diesel particulate filter (DPF) is included to meet stringent emissions standards. The 10-speed automatic transmission, co-developed with Allison, is a key component of this powertrain. Its wide gear ratio spread allows for both strong acceleration and relaxed highway cruising, while also contributing to fuel economy. The transmission is electronically controlled and features driver-selectable modes.
Driving Characteristics
The 305 horsepower and 671 Nm (494.9 lb-ft) of torque produced by the Duramax engine provide the Yukon XL V with impressive towing capacity and effortless acceleration, especially when considering its substantial weight. While not a performance-oriented SUV, the diesel engine delivers a broad torque curve, making it well-suited for hauling heavy loads or navigating challenging terrain. Compared to the gasoline-powered Yukon XL models, the diesel variant offers a more relaxed driving experience, particularly at highway speeds. The 10-speed automatic transmission generally shifts smoothly and efficiently, although some drivers may notice occasional hunting for the optimal gear in certain situations. The gear ratios are optimized for both towing and fuel economy, with lower gears providing ample torque for pulling and higher gears keeping engine RPMs low during cruising.
Equipment & Trim Levels
The 2024 Yukon XL V, even in its base configuration, comes well-equipped with features such as tri-zone automatic climate control, an 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of advanced safety features including automatic emergency braking and lane departure warning. Higher trim levels add features like a larger 12.3-inch touchscreen, a premium Bose audio system, leather upholstery, heated and ventilated front seats, and a panoramic sunroof. Optional extras include adaptive cruise control, a rear-seat entertainment system, and power-retractable side steps. Interior upholstery typically consists of cloth in lower trims, with leather becoming standard on higher-end models. Dashboard configurations are generally consistent across trims, with variations primarily in trim materials and feature availability.
Chassis & Braking
The Yukon XL V utilizes a body-on-frame construction, providing a robust and durable platform. The suspension system consists of an independent coil spring setup at the front and an independent multi-link spring suspension at the rear. Air suspension is available as an option, offering adjustable ride height and improved ride comfort. Braking duties are handled by ventilated discs at all four corners, with the front discs measuring 343×30.4 mm and the rear discs measuring 345×20 mm. An anti-lock braking system (ABS) is standard. Steering is provided by a rack-and-pinion system with electric power steering.
Market Reception & Comparison
The GMC Yukon XL V with the 3.0 Duramax engine has been generally well-received by critics and consumers alike. Its primary advantage lies in its superior fuel economy compared to gasoline-powered Yukon XL models, particularly when towing. While the initial purchase price is higher, the long-term cost of ownership can be lower due to reduced fuel expenses. Compared to the 5.3L or 6.2L V8 engines offered in other Yukon XL trims, the Duramax provides a different driving experience – prioritizing torque and efficiency over outright horsepower. Reliability has been generally good, although diesel engines can be more complex to maintain than gasoline engines.
Legacy
The LZ0 Duramax engine has proven to be a reliable and durable powerplant in other GM applications, suggesting a positive long-term outlook for the Yukon XL V. As the demand for fuel-efficient full-size SUVs continues to grow, the diesel-powered Yukon XL V is likely to maintain a strong presence in the used car market. Its combination of spaciousness, towing capability, and improved fuel economy makes it a compelling option for buyers seeking a versatile and practical vehicle. The 10-speed automatic transmission, while relatively new, has also demonstrated good reliability in other GM vehicles, further bolstering the powertrain’s long-term prospects.
