2025 Chevrolet Silverado in Roanoke, VA - $56,543

The new 2015 Chevrolet Silverado HDs are engineered to be stronger, smarter, and more confident than ever. Silverado HD's all-new exterior communicates strength and capability, while also enhancing aerodynamics for improved efficiency and reduced wind noise, It also improves cooling for more consistent power under tough conditions.

"The passion we have for trucks is reflected in every line and powerfully sculpted machined surface of the HD Chevrolet," said Tom Peters, design director. "From the dramatic sculpture of the one-piece structural bumper, to its muscular hood and side profile, the design reflects a function-driven solution."

The design of the 2015 Silverado HD is as much about brains as brawn. New inlaid doors, which fit into recesses in the body side, help reduce wind noise for a quieter cab. The smallest details of the body, such as the roof and tailgate spoiler, were tuned in a wind tunnel to smooth airflow over the truck for reduced noise and improved aerodynamic efficiency.

Other updates for the 2015 Silverado HD include: integrated cruise control, Auto Grade Braking and Diesel Exhaust Braking (on diesel models) that help make tough towing easier; standard StabiliTrak with Trailer Sway Control on all models including 3500 duallys; new 6.5- and 8-foot boxes with standard CornerStep bumpers, EZ Lift and Lower tailgates.

Silverado HD is available in more than 150 combinations of cabs, bed lengths, powertrains, drivetrains and axle ratios, enabling customers to spec exactly the right truck for their towing and hauling needs.

Power for the Silverado HD starts with a Flexfuel 6.0L V8 or a 6.0L bi-fuel V-8 engine which can run on either gasoline or compressed natural gas. Both engines are bolted to a Hydra-Matic 6L90 six-speed automatic transmission. The automaker's brawny Duramax 6.6L V8 turbo-diesel engine is optional and meshed with an Allison 1000 six-speed automatic transmission.

The foundation of the 2015 Silverado HD 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 independent front suspension is specifically engineered for HD pickup use, with forged steel upper control arms and precision machined cast iron lower control arms. Torsion bars are tailored to the weight ratings of the trucks, ad allow easier trim height adjustment to account for the weight of snow plows or other accessories.

Rear springs are asymmetrical leaf springs, which balance ride and load carrying, and improve control of axle hop. The steel springs, three inches wide, have been proven to perform year after year under the toughest conditions.

Inside the passenger cabin, the 2015 Silverado HD receives the same updates to the interior, cab structure, and door designs as the new Silverado 1500. The upright instrument panel, six-gauge instrument cluster and multiple storage options are tailored specifically to the needs of truck customers. Controls are functional, logically placed and easy to operate with work gloves on. For example, the available Integrated Trailer Brake Controller is mounted high on the left side of the instrument panel, where it can be easily adjusted, and it displays Gain on the Driver Information Center in the instrument cluster.

The new Chevrolet MyLink, standard on all models except the base work truck, provides easy-to-use connectivity for the job site or the family vacation, with natural voice recognition and enough ports and power outlets to support multiple devices.

The new truck cab is stronger, with nearly two-thirds of the structure made from high-strength steel for a confident feel and improved safety. The cabs feature inlaid doors, which fit snugly into recesses in the body sides for reduced turbulence and wind rush. Combined with new triple door seals, the doors help create a quieter interior. The rear doors on crew-cab models are larger, and combined with revised seats, create approximately two inches more rear legroom, and enable easier entry and exit for back seat passengers.

A new double-cab model, which features forward-hinged rear doors, replaces the previous extended cab, and allows easier access to the back seat, especially in tight parking spaces.
