The 2017 GMC Sierra 2500HD stands as a footprint in the heavy-duty pickup truck category with impressive power and towing abilities. This third-generation model is presented with three trims – the base, SLE, and Denali – and two engine options: a 6.0L V8 with 360 hp and a 6.6L turbodiesel V8 with 445 hp. The vehicles are equipped with a robust six-speed automatic transmission. The Sierra 2500HD is always ready to get the job done with its Advanced Trailering System, and IntelliBeam headlamps add to its safety portfolio. A 7-inch or optional 8-inch touchscreen infotainment system with Apple CarPlay and Android Auto is a highlight for tech enthusiasts. The 2017 update brought us a new hood scoop design that helps with engine-cooling for the diesel model.
