We expect the 2019 GMC Sierra 1500 to be completely overhauled, consisting of a redesign and re-engineering. The update will come six years after the launch of the current, third-generation Sierra, thereby marking the fourth generation of the Sierra nameplate.

Following are our expectations of the 2019 GMC Sierra 1500:

  • All-new platform consisting of GM’s next-generation GMT
  • All-new exterior design, incorporating the latest GMC design language and widespread use of aluminum and mixed materials, similar to the , resulting in a lower curb weight, helping improve fuel economy and overall performance
  • All-new interior design, incorporating the latest best practices and improved materials
  • Revamped technologies, including many items sought for by many in the third-generation Sierra, including keyless open, push-button start, and more
  • Improvements to the powertrain lineup, including:
    • The EcoTec3 line of naturally-aspirated V-6 and V-8 gasoline engines will likely remain, as will the hybrid-electric eAssist model
    • A turbo-charged six-cylinder gasoline engine and turbo-diesel six-cylinder engine are possible
    • All-new transmission, likely consisting of GM’s new 10-speed transmission family co-developed with Ford
  • Lighter weight, improved fuel economy, towing and payload ratings
  • Improved refinement, NVH and convenience levels

As per tradition, the 2019 Sierra is expected have a lot in common with the , including the architecture, powertrain lineup, and more. Exterior styling will likely be substantially different between the two models, while cabin design will likely be common between both vehicles, with the biggest difference being lighting color and differences in materials.
