Powertrain - GMC Dealership near Castle Rock, CO
The 2026 Yukon XL powertrain lineup centers on three proven engines paired with a responsive 10-speed automatic transmission. The standard 5.3L V-8 delivers 355 hp for confident acceleration and relaxed highway cruising, while the available 6.2L V-8 raises output to 420 hp for effortless passing with a full complement of passengers and cargo. For maximum low-end grunt and serenity on long drives, the available 3.0L Duramax Turbo-Diesel inline-six makes 305 hp and a stout 495 lb-ft of torque, with peak twist arriving below 2,000 rpm to help launch trailers and maintain speed on grades with fewer shifts. Rear-wheel drive remains a great choice for balanced towing and efficiency, while four-wheel drive adds all-weather confidence and trail readiness. Properly equipped, Yukon models can tow up to 8,400 pounds, making boats, campers, and toy haulers part of the weekly routine rather than a special occasion. The 10-speed’s close ratios and smooth calibration keep the engine in its sweet spot, whether you’re easing through traffic or ascending to higher elevation trailheads. Whichever engine fits your lifestyle, the Yukon XL’s powertrains are built to feel strong, refined, and ready for the long run.
