General Motors introduces the new 2007 Chevrolet Silverado and GMC Sierra heavy-duty pickups, with all-new and differentiated exterior designs, two unique interiors and class-leading power and efficiency. The redesigned pickups incorporate brand-distinct exterior and interior designs that are greatly differentiated from the light-duty trucks, along with a choice of gas and diesel powertrains. Capabilities are enhanced and complement new, segment-leading and segment-exclusive features.

Silverado and Sierra are offered in a range of 2500HD (three-quarter-ton) and 3500HD (one-ton) models, reaffirming GM's nearly 100-year legacy of building heavy-duty trucks. The 2007 models offer unprecedented levels of performance, capability and refinement. Silverado is available in WT, LT and LTZ trim; Sierra is available in WT, SLE and SLT trim - all with differentiated appearance and interiors.

"There's not a broader, more powerful or more capable lineup of heavy-duty pickups in the industry," said Gary White, GM North America vice president and vehicle line executive of full-size trucks. "But along with the capability and functionality that our customers expect, the 2007 Silverado and Sierra heavy-duty trucks meld exceptional refinement and surprising attention to detail."

The range of configurations - three cab styles, three cargo box styles and five wheelbase lengths - delivers tremendous choice. Some full-size truck manufacturers do not even offer three-quarter-ton or one-ton heavy-duty trucks. And among those that do, the 2007 Silverado and Sierra HD pickups offer many segment-best capabilities, including 18,500-pound (8,392 kg) gross combined vehicle weight rating for vehicles with a gas V-8 and a 13,000-pound (5,897 kg) conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 16,700 pounds (7,575 kg), when equipped with a fifth-wheel hitch.

"GM's heavy-duty pickup heritage is built on the promises of function and dependability," said White. "The new Silverado HD and Sierra HD trucks offer exceptional capability, while building on the reputation that has put GM full-size pickups at the top of numerous quality surveys."

Chevy Silverado and GMC Sierra 2500HD and 3500HD models will arrive in the first quarter of 2007. Production of the new trucks is shared among several assembly plants, including Fort Wayne , Ind. , and Pontiac and Flint , Mich.

Bold and distinctive exterior designs

The new Silverado and Sierra heavy-duty models have bolder, muscular designs that are differentiated from their light-duty siblings. This includes new grilles, headlamps, hoods and front fenders - all conveying broad-shouldered, ready-for-anything strength. The trucks also feature more distinct brand differentiation than any previous generation.

Chevy Silverado has a wider and taller dual-port grille, with a prominent gold bow tie emblem at the center. Large, reflector-optic headlamps and corner lights wrap around the front end and flow into flared front fenders, enhancing the truck's broad stance. The fender flares have a chiseled, squared-off appearance and complement the strong power dome hood design.

GMC Sierra has a distinctive front end with a prominent GMC emblem set in a large, chrome-ringed grille (black grille surround on work truck models). The grille is flanked by large, jeweled-appearance headlamps. Chrome bumpers with body-color top and end caps are standard. SLE models feature large foglamps set into the bumper, creating an upscale appearance that further reflects GMC's brand identity.

The trucks' door handles feature large, grab-style designs that are easy to open with gloves. Other details also enhance the strong appearance and functionality includes larger front recovery hooks. A faster, 57-degree windshield angle reduces wind noise and improves fuel efficiency.

The trucks are more refined looking, too, with doors that extend over the rockers for a smooth, uninterrupted look, and lamps that have a jeweled appearance. Tolerances between panels are greatly reduced - including a 50-percent reduction in the space between the cab and cargo box.

Cab and cargo box configurations

Silverado and Sierra heavy-duty trucks are offered in regular, extended and crew cab configurations, which are complemented with standard (6-foot 6-inch) and long (8-foot) cargo box lengths. Silverado and Sierra 3500HD models also are available with the Dually dual rear wheel configuration on a long (8-foot) box. New features, such as 170-degree-opening rear access doors with fully retractable power windows on extended cab models, offer increased versatility.

The pickup boxes have been redesigned with enhanced versatility, increased strength and greater capacity. A one-piece wheelhouse and inner box side add strength and a smoother, more integrated appearance. The boxes are 1.18 inches (30 mm) deeper in the front and 1.57 inches (40 mm) deeper at the rear, with stronger inner walls that offer improved performance when fitted with ladder racks, tool boxes and other accessories. Cargo bed volume is 60.7 cubic feet (1,718 L) with the regular box and 75.5 cubic feet (2,138 L) with the long box.

Dually cargo boxes are made of all steel, including new, hydroformed sheet metal outer fenders. They have a smooth, integrated appearance and enhanced strength. All Dually models feature marker lights on the fenders and new, sleek cab roof lights that are aerodynamically integrated into the top of the cab.

New tailgate designs include a lock and an available EZ Lift feature, with torque-rod assist. Despite being larger than previous models, the new tailgates are easier to use, thanks to revised construction that reduces overall mass. The tailgates are easily removed by simply opening to 45 degrees and pulling straight out and away from the vehicle.

A new, innovative cargo management system is available on all Silverado and Sierra models and is complemented by a range of dealer-ordered accessory packages. Three rails that run the length of the box sides and the forward box wall are secured with high-strength anchors and, unlike competitors' systems, incorporate upper and lower tracks. Four adjustable tie-down brackets are included with each system and can be located anywhere on the tracks, each rated for a load point of 500 pounds (227 kg).

At the heart of a comprehensive accessories portfolio for the new pickups is a group of specific accessory products designed to integrate into the cargo management system. The rails enable the use of an overhead utility rack rated at 500 pounds (227 kg) loading capacity, a sliding diamond plate toolbox, a sliding bed divider, diamond plate side storage boxes or a bicycle mount. These accessories use either the upper or lower rails, allowing numerous combinations that can easily fit together or bypass one another as they slide along the rails. The tool boxes and bicycle mount use a codeable lock, enabling the vehicle key to be used for locking and unlocking these accessories.

Segment-leading interior designs with superior craftsmanship

Chevy Silverado and GMC Sierra HD pickups are quieter, more spacious and refined inside, with increased passenger comfort and storage space. They each feature two new and distinct interior designs that reflect their respective brand identities, including specific trim, appointments and gauge cluster appearance.

Silverado and Sierra HD base and midlevel trim models include a functional pure pickup interior design theme with a contemporary adaptation of GM's ergonomic cockpit instrument panel design. In addition, this interior includes specific door panels with large door pull and release handles, new seat construction and configurations, unique center console and underseat storage systems, and two glove boxes (a traditional lower glove box and a covered upper storage compartment).

New luxury-inspired premium interiors are standard on Silverado LTZ and Sierra SLT. They offer richly appointed features, including a distinct instrument panel design, large-capacity center console (20.1 L), specific door panels, seats and other trim elements. Features on the premium interiors include power-adjustable heated bucket seats, leather surface seats, leather-covered steering wheel and selective chrome trim.

Spaciousness in each interior trim level is enhanced with new, "low and forward" instrument panels that provide a more airy feel to the cabin as well as a panoramic field of vision. The instrument panels are mounted approximately 3.5 inches (90 mm) down and forward on the pure pickup interiors, while the premium interior instrument panel is located 5 inches (127 mm) down and forward. Both instrument panel designs are integrated into their specific door panels to create a swept appearance.

The spacious interior and enhanced field of vision create an environment that enables better outward vision. Legroom, headroom and hip room also have increased. The recline angle and fore/aft travel of the front seat have been increased.

All interiors are refined and craftsmanship is highlighted by flush surfaces, tight gaps and tolerances on the instrument panel, center stack, clusters and other components. Most gaps on the instrument panels and clusters have been narrowed to 0.5 mm or less. Attention to detail was given to concealing fasteners and metal structural components of all seats. There is no exposed hardware in the interior or door sills. New, soft-touch and low-gloss finishes for the instrument panels and other trim pieces are used throughout. The color and grain of the materials were carefully selected to provide a premium look. Sculpted headliners of new woven fabric and door trim, as well as sculpted seat backs, enhance the perception of precision in the new interiors.

Complementing the interiors' finely crafted look and feel is segment-leading quietness. All trim levels - even base work truck models - benefit from a comprehensive system that delivers a passenger environment almost devoid of noise. This is achieved with the use of strategically placed sound-deadening and sound-absorbing material in the body structure - including liquid-applied dampener on the floor and front-of-dash - as well as the inherent, vibration-minimizing traits of the stiffer frame and quieter attributes of the aerodynamically tuned exterior. Also, improved door sealing and a doors-over-rockers design help eliminate road and wind noise.
