The 2017 GMC Sierra 2500HD Crew Cab Denali with the 6.6L Duramax turbo-diesel is a true powerhouse that blends rugged capability with upscale comfort. Its L5P Duramax packs 445hp and a staggering 910lb-ft of torque, delivering effortless towing—up to around 15,400lb conventional or 18,100lb fifth‑wheel when properly equipped—while rarely working hard. Owners praise its refined and surprisingly quiet cabin, where triple‑sealed doors and sound insulation mute the diesel’s growl. Luxuries like heated/cooled leather seats, Bose audio, Apple CarPlay/AndroidAuto, and an 8-inch touchscreen make it feel more premium than utilitarian. All that capability wrapped in Denali styling makes it one impressive heavy‑duty luxury pickup.
