GMC Sierra 1500 Denali Ultimate Mechanical specs
Under the skin, Sierra 1500 Denali Ultimate is engineered to feel poised and predictable on broken pavement, gravel approaches, and winding mountain passes. Denali Premium Suspension with Adaptive Ride Control continuously monitors the road and vehicle inputs, making micro-adjustments that help deliver a composed ride whether you’re cruising I-25 or a washboard access road. Standard Hill Descent Control takes the stress out of steep declines by managing brake modulation, while selectable Traction Modes let you tailor responses for Sport, Tow/Haul, and available Off-Road settings as conditions change. Up to 14 available camera views can assist with tight maneuvering and trailering alignment, and the in-vehicle Trailering App supports custom trailer profiles, pre-departure checklists, and diagnostics you can access from the center screen. The Sierra 1500’s robust chassis and 4WD configuration on Denali Ultimate help put power to the ground with sure-footed control, and the short bed configuration provides a thoughtful balance of maneuverability and cargo space. From urban errands to jobsite demands and weekend escapes, the mechanical formula prioritizes stability, confidence, and the quiet strength you expect from a premium pickup.
Powertrain - GMC Dealership near Denver, CO
The heartbeat of the Denali Ultimate is its standard 6.2L EcoTec3 V8 engine paired to a 10-speed automatic transmission, an effortlessly strong combination rated at 420 horsepower and a robust 495 lb-ft of torque.
