The 2017 GMC Sierra 1500, part of the pickup's third generation, slots into the full-size truck category. Available in four trims – Base, SLE, SLT, and Denali, each offering either rear-wheel or four-wheel drive – it provides a wide array of options to choose from. It sports three engine choices: a 285-hp 4.3-liter V6, a 355-hp 5.3-liter V8, and a beefy 420-hp 6.2-liter V8, each paired with a six-speed automatic transmission, while the 6.2L V8 and 5.3L V8 models also offer the option of an eight-speed automatic. Notable features of the 2017 Sierra 1500 include a 7-inch or a larger 8-inch touchscreen, Apple CarPlay and Android Auto compatibility, and available driver assist technologies like forward collision warning, lane keeping assist, and low-speed automatic emergency braking. The Sierra stands out amongst the competition with bold styling, a quiet cabin, and plush materials, particularly in the upscale Denali variant.
