Specs at a Glance
If you need a heavy-duty workhorse, look no further than the 2026 GMC Sierra HD. This pickup truck's high towing capacity, comfortable interior, and user-friendly features make it hard to beat. When shopping for a new Sierra HD, some drivers will be choosing between the Pro and Denali trim levels. Here's an overview of how these two trims compare.
Performance
Both trims come standard with a robust 6.6-liter V8 gas engine. It develops 401 horsepower and 464 lb-ft of torque. A 10-speed automatic transmission shifts power to the wheels. Drivers who need more muscle can opt for a 6.6-liter, turbo-diesel V8 engine, tuned to generate 470 horsepower and a monstrous 975 lb-ft of torque.
While the Pro trim comes standard with rear-wheel drive, it offers four-wheel drive as an option. Meanwhile, the Sierra HD Denali comes standard with four-wheel drive. GMC also equips the Denali trim with Digital Variable Steering Assist. This feature enhances the pickup's overall maneuverability, thus reducing driver fatigue.
Appearance
The Sierra HD Pro's tough-nosed exterior makes it perfect for the everyday grind. It comes standard with 17-inch steel wheels, which are ideal for harsh environments. Modern LED headlights and taillights are included as well. When towing a load, you'll appreciate the pickup's large towing mirrors.
Expect the more luxurious Denali trim to have an especially upscale appearance. Its 20-inch Ultra-Bright aluminum wheels and chrome exterior details make a bold statement. Side assist steps further set the Sierra HD Denali apart.
Features
When behind the wheel of the Sierra HD Pro, a modern infotainment system enhances your driving experience. It features a 7.0-inch touchscreen with wireless Apple CarPlay/Android Auto smartphone integration. This trim's vinyl seats and floor coverings offer excellent durability. Another great feature is the HD Rear Vision camera.
The Denali trim is geared towards drivers who desire top-tier luxury. Its 12-way heated and ventilated power front seats take comfort to the next stage. Upgraded tech features, such as a larger 13.4-inch touchscreen with Google built-in, add to the Denali trim's upscale nature. Some of the other highlights include a 12.3-inch digital gauge cluster, dual-zone automatic climate control, a Bose premium sound system, and premium leather upholstery.
