The 2013 GMC Sierra 1500, part of the twelve-year-long third generation, is a full-size pickup truck offering both practicality and power. With available trims including the Work Truck, SLE, SLT, and Denali, this truck can be tailored to meet various needs. Standard rear-wheel drive (with optional four-wheel drive) pairs with a selection of engines, starting from a 195-horsepower, 4.3-liter V6 up to a robust 403-horsepower, 6.2-liter V8 available in the top-tier trim. Most models use a four-speed automatic transmission, although a six-speed is available on some trims. Key features include satellite radio, OnStar communication system, and cruise control as a standard. Safety-wise, all models include stability control, full-length curtain type airbags in addition to the typical front and side airbags. No significant changes were made for the 2013 model year.
