The 2021 GMC Terrain will soon arrive at Capital GMC Buick, and while all of the details regarding pricing and upgrades for Canadian models have yet to be revealed, there are a few things we know from advance reports. One of the major changes is the addition of an off-road ready Terrain AT4 model, which is sure to capture the interest of drivers throughout the Edmonton area. This 2021 vs. 2020 GMC Terrain comparison will help you find out what’s new and what’s the same between model years.  



2021 vs. 2020 GMC Terrain: What’s Changed?

While the 2021 Terrain carries over many of the standard features of the 2020 model, there have been a few changes made between model years. 

  • The diesel engine will no longer be available 
  • Smokey Quartz Metallic has been removed from the exterior color options.
  • The Driver Alert Package has been renamed to GMC Pro Safety Plus and will be standard on all Terrain trim levels.
  • The SLT Chrome Package will not be offered.
  • The Denali model will have a late availability.

The big news is the new 2021 GMC Terrain AT4 model. The AT4 will provide stellar off-road capabilities and will feature a rugged exterior along with advanced tech features to make your next adventure outside of Sherwood Park more enjoyable than ever. If the 2021 GMC Sierra AT4 is any measure, you may expect the Terrain AT4 to come with a factory-installed lift, all-terrain tires, and exclusive AT4 badging.
