Select trim levels brag with an 8.0-inch touchscreen. In addition to the Tire Pressure Monitoring system on single rear wheel models, the 2018 Chevrolet Silverado HD adds Tire Fill Alert. Having made its U.S. debut on the 2018 GMC Acadia, the said technology is designed to provide visual/audible alerts when inflating a tire to the recommended pressure.
From the point of view of exterior design, 2018 sees the deletion of three colors: Pepperdust Metallic, Butte Red Metallic, and Siren Red Tintcoat. In their place, the golden bowtie added Havana Metallic and Cajun Red Tintcoat. High Country models are garnished with a new black mesh grille, boasting a two-bar chrome insert, whereas the Silverado HD in Z71 configuration also boasts a fresh design for the front grille. And finally, look forward to a handful of new side decals for the Z71 and 4×4 models.
