Powertrain - GMC Dealership near Denver, CO

Performance choices let you tailor Denali to your priorities. The 5.3L V8 pairs with a 10-speed automatic transmission for confident acceleration and dependable everyday power. Drivers who want a more assertive throttle and authoritative highway merging can choose the available 6.2L EcoTec3 V8, also mated to a 10-speed automatic, for a deeper well of response. For those who value range and low-end pull, the available Duramax® 3.0L Turbo-Diesel partners refined torque with smooth power delivery—ideal for long stretches between fill-ups and steady towing. Max available horsepower reaches up to 420 hp, while max available torque is rated up to 495 lb-ft, underscoring the Sierra’s strong work ethic when properly equipped. The powertrains integrate with Tow/Haul mode and the truck’s trailering technologies to help optimize shift points and stability with a load in tow. This is where engineering polish meets practical needs: brisk passing power on mountain highways, controlled low-speed maneuvering on job sites, and relaxed cruising during long drives. For shoppers seeking a luxury pickup with the muscle to back up its refined interior and exterior, the 2025 GMC Sierra 1500 Denali makes a compelling case.

Safety - 2025 GMC Sierra 1500 Denali dealer

Driver confidence grows from comprehensive systems that feel natural and easy to use. Denali and Denali Ultimate models provide Adaptive Cruise Control as standard equipment, helping maintain a selected following gap to traffic ahead. Available Super Cruise® hands-free driver assistance technology further elevates long-distance driving on compatible roads, and it is designed to function while trailering for added convenience. An array of camera views and driver-assistance tools can support close-quarters maneuvering and trailer hookups, while the chassis itself brings poise to sudden inputs and mixed-surface driving. Hill Descent Control is standard for controlled descents, and Selectable Traction Modes help the truck feel composed in varied conditions. Available OnStar® technology adds another layer of reassurance with helpful services and in-vehicle apps. As always, each feature is designed to assist, not replace, attentive driving; but taken together, these systems contribute to an overall feeling of calm capability. For many customers, safety is as much about how a truck behaves in daily traffic as how it performs when the route turns steep or unpaved—and Denali addresses both with thoughtful tuning and accessible technology.
