Segment-leading interior designs with superior craftsmanship
Chevy Silverado and GMC Sierra HD pickups are quieter, more spacious and refined interior, with increased passenger comfort and storage space. Each with two new and distinct interior designs that reflect their respective brand identities, including the trim, appointments and gauge group appearance.
Silverado and Sierra HD base and midlevel models include a functional pure pickup trim interior design with a contemporary issue of adapting the instrument panel MM ergonomic cabin design. In addition, this interior includes 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 upper deck of storage compartment).
New luxury-inspired premium interiors are standard on Silverado LTZ and Sierra SLT. They offer richly appointed features, including an instrument panel design, large-capacity center console (20.1 L), specific door panels, seats and other elements of court. Features of the premium interiors include power-adjustable heated seats, leather surface seats, leather-covered steering wheel and selective chrome cutting.
Spaciousness in each interior trim level is enhanced with new “low and forward” instrument panels that provide a more airy feel to the cabin and a panoramic field of vision. The instrument panels are mounted approximately 3.5 inches (90 mm) and move up in 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 your door panels to create a swept appearance.
The spacious interior and enhanced field of vision create an environment that enables better outward vision. Legroom, hip room also have increased height. The angle of recline and front / aft front seat travel has 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 groups have been reduced to 0.5 mm or less. Attention to detail is the possibility of concealing fasteners and metal structural components of all seats. Hardware is not exposed in the interior or door sills. New, soft-touch and low gloss finishes for the instrument panels and other parts are used throughout. The color and grain of the materials were carefully selected to offer a premium look. Sculpted headliners of new fabrics and door trim, seats and sculpted, improve the perception of accuracy in the new interiors.
Complementing the interiors’ finely drawn appearance and segment-leading quietness. All trim levels – even base models of trucks working – benefit from a comprehensive system that offers a passenger environment almost devoid of noise. This is accomplished through the use of strategically placed sound deadening and sound absorbing material in the body structure – including liquid damping applied on the ground in front of dash – as well as the inherent, vibration of the minimization of the features stiffer frame and quieter attributes of the aerodynamically tuned exterior. Also, the improvement of a closing door and doors through rockers design help eliminate road and wind noise.
