When you spend long days on the worksite or long nights towing a heavy trailer, comfort and capability are hardly a luxury. With its quiet, well-appointed interior and advanced technologies that bring extra confidence to the most challenging towing situations, the 2015 Silverado High Country HD has what it takes to make the tough jobs easier. Silverado High Country HD, Chevrolet’s first premium heavy-duty pickup, combines the refinement and convenience of the Silverado 1500 High Country with the rugged capability of the new Silverado 2500HD and 3500HD pickups. Luxury for go, not for show Unique content includes a chrome grille with horizontal bars, and body-color front and rear bumpers – including Chevrolet’s CornerStep rear bumper. All models include 6-inch tubular chrome assist steps, High Country badges on the doors and tailgate and High Country logos on the door sill plates. Silverado 2500HD High Country models also feature a unique 20-inch chrome wheel. Single-rear-wheel 3500HD models have an 18-inch chrome wheel, while dual-rear-wheel models use a 17-inch forged polished aluminum wheel. Inside, Silverado High Country HD features an exclusive saddle brown interior. Heated and cooled perforated premium leather front bucket seats with High Country logos on the headrests are standard, along with Chevrolet MyLink connectivity with an 8-inch touch screen, Bose premium audio and front and rear park assist. Options include a sunroof, navigation system and a rear-seat entertainment system with a BluRay/DVD player, as well as a High Country Premium Package that includes heated steering wheel, driver alert package and power adjustable pedals. New trailering mirrors available Also available on the Silverado HD High Country are Chevrolet’s new up-level trailer tow mirrors. The chrome-capped mirrors manually extend for wider trailers and feature power adjust with memory and power fold. They include heat and turn signals in the glass. They also incorporate auxiliary clearance lamps and auxiliary cargo lamps to help make backing a trailer easier. Engineered for capability, built for dependability Under the skin, the new High Country models are 100 percent Silverado HD, engineered to tame the toughest tasks and validated by the team that has helped make Silverado the most dependable, longest lasting pickups on the road. The High Country comes in 2500HD and 3500HD crew cab models in both two- and four-wheel-drive. The 3500HD High Country will be available in single- or dual-rear wheel models, with maximum tow ratings of up to 22,900 pounds for fifth wheel/gooseneck towing, and up to 19,600 pounds for conventional towing. Like other Silverado HDs, the High Country HD will offer a choice of three powertrains: A 6.0L V-8 specifically tuned for heavy-duty trucks, rated at 360 horsepower and 380 lb-ft of torque. A bi-fuel version of the 6.0L V-8 that can seamlessly switch from gasoline to Compressed Natural Gas (CNG). The 6.6L Duramax turbodiesel teamed with the Allison 1000 six-speed automatic transmission. Rated at 397 horsepower and 765 lb-ft of torque, the Duramax V-8 features a variable-vane turbocharger that acts as an exhaust brake, helping control speed on downgrades for more confident towing. The foundation of the 2015 Silverado HD lineup is a family of fully boxed frames, which use large cross sections, hydroforming and high-strength steels in key areas. The stiffness of the frames contributes to improved handling and ride comfort while the strength of the frames enhances payload and towing capability. The Silverado HDs employ an independent front suspension specifically engineered for HD pickup use. Torsion bars tailored to the weight ratings of the trucks allow easier trim height adjustments. In the rear, asymmetrical leaf springs balance ride-and-load carrying and improve control of axle hop. The new Silverado HDs are engineered to bring new levels of confidence to tough towing through further refinement of Silverado’s available cruise control, auto grade braking, and diesel exhaust brake. Integrating these features helps the 2015 Silverado HD maintain a set speed up and down grades, even when towing a heavy trailer in mountainous terrain. Silverado 2500HD and 3500HD High Country models will be available starting this summer. Source: GM
