2026 GMC Sierra 1500 Denali Ultimate

The 2026 GMC Sierra 1500 Denali Ultimate brings premium truck capability, diesel efficiency, and bold GMC presence together in one refined package. Offered by Steele Chevrolet Buick GMC in Dartmouth, this four-door Crew Cab stands out in Black with an Alpine Umber interior. Its 3.0L turbocharged diesel I6, automatic transmission, and four-wheel drive layout make it ready for work, travel, and daily use.
