The 2015 Chevrolet Silverado 3500HD CC is the heavy-duty variant of Chevrolet's full-size truck. Available in various configurations, two engine options are offered: a 6.0L V8 Gasoline engine (322 horsepower and 380 lb-ft of torque) and a 6.6L V8 Duramax Turbo-Diesel engine that generates 397 horsepower and 765 lb-ft of torque. Both engines are paired with a 6-speed automatic transmission, and consumers have the option of choosing between RWD and 4WD drivetrains. The Silverado 3500HD CC comes in three trims (Work Truck, LT, and LTZ), with each progressively adding on more comfort and technology features. Safety equipment includes standard airbags, antilock brakes, and stability control, particularly important for managing heavy loads. An optional Driver Alert package adds forward collision alert, lane-departure warning, and a Safety Alert seat.
