2019 GMC Sierra 1500 Light-Duty
As stated, the 2019 GMC Sierra 1500 was completely overhauled, consisting of a redesign and re-engineering. The update comes six years after the launch of the current, third-generation Sierra, thereby marking the fourth generation of the Sierra nameplate.
Highlights
Following are highlights of the 2019 GMC Sierra 1500:
- All-new platform consisting of GM’s next-generation GMT T1 platform
- All-new exterior design, incorporating the latest GMC design language and widespread use of aluminum and mixed materials, similar to the Cadillac CT6, 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
- Lighter weight, improved fuel economy, towing and payload ratings
- Improved refinement, NVH and convenience levels
As per tradition, the 2019 Sierra has a lot in common with the 2019 Chevy Silverado, 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.

2019 GMC Sierra HD
The 2019 GMC Sierra HD family, consisting of Sierra 2500HD and Sierra 3500HD, carries over from the 2018 model year with a few minor changes to colors, equipment, or option packages. The Sierra HD will adopt the T1 platform and design of the 2019 Sierra 1500 for the 2020 model year.

- Model Line

Beyond 2019
We expect the following future for the Sierra beyond the 2020 model year:
- The light-duty Sierra 1500, now in its fourth generation as of the 2019 model year, should remain in production thru the 2025 model year
- The heavy-duty Sierra 2500HD and 3500HD, will see its final third-gen year, and enter their fourth generation as of the 2020 model year, should remain in production thru the 2026 model year
An all-new, next GMC Sierra will launch after the aforementioned models reach the end of their respective lifecycles.
