2015 CHEVROLET SILVERADO HD: Built strong, with best-in-class conventional towing, the 2015 Chevrolet Silverado 2500HD and 3500HD are among the heavy lifters in Chevy’s truck lineup. Customers who use full-size trucks will appreciate the all-new exterior styling that includes enhanced cooling air flow, and the all-new cabs with increased comfort, space and extensive storage space. There is an expanded list of Chevrolet bi-fuel trucks that run on either gasoline or compressed natural gas (CNG), and standard StabiliTrak with Trailer Sway Control on all models including 3500HD duallys. For MY2015, Silverado 2500HD and 3500HD models are available in Work Truck (WT), LT and LTZ trims, and in regular cab, double cab and crew cab configurations. The new double cab model replaces the previous extended cab and features forward-hinged rear doors, which allow easier access in tight parking spaces. Consumers have a choice of a Vortec 6.0-liter V-8 that delivers 360-horsepower, or the 397-hp Duramax 6.6-L turbo-diesel V-8. Both are backed by either a Hydra-Matic or Allison 1000 six-speed automatic transmission. Available features include navigation radio with a built-in hard drive, heated/cooled seats for LTZ models, and a Z71 Off-Road appearance package. Depending on setups, 17-, 18- and 20-inch wheels are offered; painted, machined aluminum or forged polished aluminum. Updates to the trailer hitch receiver enable the increase in conventional towing to 18,000-pounds from 17,000-lbs. For greater fifth-wheel towing capacity, engineers strengthened the pickup box structures along with the rear springs, U-bolts, and revised shock tuning, all of which contribute to the Silverado 3500 HD's best-in-class tow rating of 23,100-lbs, up from 21,700. Similarly, Silverado leads its class in payload, with a 7,222-lb. capacity.
