2023 GMC Sierra 1500

History/Overview

The GMC Sierra 1500 is one half of General Motors’ two-pronged approach to the full-size, light-duty pickup truck segment. Sold alongside the mechanically similar Chevrolet Silverado, it is one of Canada’s best-selling vehicles overall as we write this.

What’s New/Key Changes From Last Year

New to the Sierra 1500 this year is an AT4X package that builds on the AT4 with more off-road capability, adding extra underbody protection and a winch, among other items.
