The 2016 GMC Sierra 1500HD Classic represents the last gasp of the venerable second-generation GMC Sierra design. This full-size, Rear-Wheel-Drive truck is available in various trims, including Work Truck, SLE, and SLT, and offers four-wheel drive as an option. Under the hood, it features a robust 6.0L V8 engine that delivers up to 300 horsepower, paired with a four-speed automatic transmission. The truck provides a strong towing capacity and payload, appealing to those needing practical, rugged capability. It continues GMC's tradition of blending work-grade toughness with premium comfort features. On the infotainment side, it offers an available OnStar system, delivering turn-by-turn navigation and hands-free calling. While not as advanced as currently offered systems, GMC has always been at the forefront of integrating useful technology into its trucks. Safety features include dual front airbags, antilock brakes, and stability control. However, it lacks modern driver-assistance features.
