2020 GMC Sierra 2500HD / 3500 HD Sierra 2500HD Crew Cab Standard Box 4-Wheel Drive Denali

The GMC Sierra 2500HD operates with a four-wheel drive layout and measures 266.09 inches in overall length. This heavy pickup supports a passenger capacity of 6 occupants across front and rear split bench seating arrangements. The reinforced chassis carries a curb weight of 6741.0 lbs while maintaining 10.08 inches of ground clearance for rough worksites. Rear passengers utilize a folding bench that preserves cabin space when hauling requirements change.

Under the hood, a 6.6 liter V8 engine generates 401 hp at 5200 rpm and delivers 464 lb-ft of torque at 4000 rpm. A 6-speed automatic transmission routes that power while drawing from a 36.0 gal fuel tank capacity. The frame supports a max towing capacity of 18500.0 lbs and handles up to 3909.0 lbs of max payload. Inside, a 7.0 inch touchscreen runs the GMC Infotainment System with wireless Apple CarPlay and Bluetooth connectivity. Standard safety equipment includes frontal driver airbags, a rear cross traffic alert system, and a Teen Driver mode interface.

Ownership coverage includes a basic warranty spanning 3 years or 36000 miles alongside a drivetrain plan covering 5 years or 60000 miles. The electrical architecture relies on a 720.0 cca battery paired with a 170.0 amps alternator to support job site equipment. Buyers should note that manual climate control and a urethane steering wheel reflect a work-focused cabin rather than luxury appointments.
