Overview of the Vehicle
The 2026 GMC Sierra 2500HD delivers commanding heavy-duty performance with two powerful engine options. The standard 6.6-liter V8 produces 401 horsepower and 464 lb-ft of torque, while the available Duramax turbo-diesel generates 470 horsepower and an impressive 975 lb-ft of torque. Both engines pair with a 10-speed automatic transmission offering rear-wheel or four-wheel drive configurations. Maximum towing capacity reaches 22,500 pounds when properly equipped. While EPA doesn't test fuel economy for this weight class, real-world testing shows the diesel achieves around 17 mpg highway. Minor 2026 updates include new paint color options and expanded MultiPro tailgate availability.
Technology Highlights
Advanced infotainment features include a standard 7-inch touchscreen, upgrading to 13.4-inch displays on higher trims with Google Built-in integration. Wireless Apple CarPlay and Android Auto come standard, complemented by a 12.3-inch digital gauge cluster. Safety technology includes automatic emergency braking, lane departure warning, and available features like blind-spot monitoring and adaptive cruise control. The innovative 15-camera system provides comprehensive visibility, while the Bose premium audio system delivers exceptional sound quality throughout the spacious cabin.
