2026 GMC Sierra 3500HD Overview

For 2026, the robust GMC Sierra 3500HD continues the fifth-generation of GMC's heavy-duty lineup. The beastly truck offers two potent engine options: a 6.6L gas V8 producing 401 hp and a 6.6L turbodiesel Duramax V8 kicking out 445 hp and an earth-shaking 910 lb-ft of torque. Both engines are paired with heavy-duty six-speed and 10-speed Allison transmissions, respectively. The Sierra 3500HD is offered in the base, SLE, SLT, AT4, and range-topping Denali trim levels. Four-wheel drive is an option throughout the lineup. Key features include a trailering system that offers 15 different views to make towing easier and safer, driver assists like automatic emergency braking, and a spacious, high-quality cabin. An infotainment system with large screen, Apple CarPlay, Android Auto, and available Wi-Fi hotspot elevates the tech offering. For 2026, the Sierra's front end design receives a subtle refresh, aimed at further distinguishing it from its Chevrolet Silverado cousin.
