2021 GMC Yukon XL SLT – Satin Steel Metallic – 3.0L Duramax® Turbo-Diesel Inline-6 – 4-Wheel Drive – One Owner – 68,925 MilesPremium full-size luxury, enormous three-row versatility, impressive diesel torque, and confident four-wheel-drive capability come together in this one-owner 2021 GMC Yukon XL SLT 4WD. Finished in sophisticated Satin Steel Metallic and showing 68,925 miles, this extended-length Yukon delivers the passenger room and cargo capacity families want while surrounding everyone with the upscale comfort and technology expected from the SLT trim.Under the hood is GM’s outstanding 3.0-liter Duramax® turbo-diesel inline-six—not a V6—producing 277 horsepower and an impressive 460 lb-ft of torque. That torque arrives low in the rev range, giving the Yukon XL smooth, effortless acceleration and excellent highway cruising characteristics. The Duramax is paired with a 10-speed automatic transmission, creating a refined powertrain that takes full advantage of the diesel engine’s broad torque delivery. The 4WD diesel configuration is rated at approximately 20 MPG city and 26 MPG highway, an impressive combination for an SUV of this size and capability.The SLT trim adds a substantial level of premium equipment. Standard exterior highlights include handsome 20-inch 6-spoke polished aluminum wheels, chrome body-side accents, chrome door-handle detailing, heated power exterior mirrors, roof rails, fog lamps, IntelliBeam automatic high beams, rain-sensing windshield wipers, and a hands-free programmable power liftgate. The Satin Steel Metallic finish complements the Yukon XL’s bold GMC grille, strong shoulder lines, and commanding proportions beautifully.Inside, the SLT moves firmly into luxury-SUV territory with perforated leather seating surfaces, heated AND ventilated front seats, 12-way power-adjustable front seating, driver-seat memory, dual-zone automatic front climate control, rear climate control, and a leather-wrapped steering wheel. The cabin provides the comfort needed for long-distance travel while retaining the durability and practicality expected from a full-size GMC.Technology is centered around GMC’s 10.2-inch touchscreen infotainment system with Bluetooth® audio streaming and smartphone connectivity. Apple CarPlay® and Android Auto™ integration allow compatible phones to access navigation apps, calls, messages, music, and other supported functions directly through the vehicle’s display. A Bose® 9-speaker premium audio system, SiriusXM® with 360L, HD Radio™, multiple USB connections, remote start, push-button start, and Universal Home Remote add even more everyday convenience.The redesigned 2021 Yukon XL also brought a major improvement in passenger and cargo space thanks in part to its independent multi-link rear suspension. Behind the third row is an impressive 41.5 cubic feet of cargo room; folding the third row expands that to 93.8 cubic feet, while maximum capacity reaches a massive 144.7 cubic feet. That makes this Yukon XL exceptionally well suited for family travel, luggage, business use, sports equipment, or long road trips.Driver-confidence equipment includes Automatic Emergency Braking, Forward Collision Alert, Front Pedestrian Braking, Lane Keep Assist with Lane Departure Warning, Lane Change Alert with Side Blind Zone Alert, Rear Cross Traffic Alert, Front and Rear Park Assist, IntelliBeam automatic high beams, and an HD Rear Vision Camera.With its one-owner history, 460 lb-ft of Duramax diesel torque, 10-speed automatic transmission, 4WD capability, heated and ventilated leather seating, 20-inch polished wheels, Bose® premium audio, 10.2-inch touchscreen, smartphone integration, hands-free power liftgate, and enormous 144.7-cu.-ft. maximum cargo capacity, this Yukon XL SLT delivers an exceptional combination of luxury, efficiency, capability, and space.Now available at Action Automotive Preowned Cars, where quality vehicles are carefully selected for performance and value.
