The GMC Terrain is getting a refresh for the 2021 model year, which we more or less saw a few weeks ago. But before that model actually begins arriving at dealers around the third quarter of 2020, we have the 2020 Terrain, which is getting a few updates and changes of its own. So, here’s what’s new and different about the 2020 GMC Terrain.
As we reported previously, the Terrain does away with the 1.6L Turbo Diesel LH7 engine for the 2020 model year in both FWD and AWD formats. This results in the deletion of the SLE Diesel (3SB) and SLT Diesel (4SB) trim levels that hosted the diesel engine. No other changes to the model line take place for the 2020 GMC Terrain.
On the outside, the 2020 Terrain gains one new exterior color while losing two others:
- Blue Steel Metallic
- Sedona Metallic
The only other change to the exterior is that the bright rear bumper protector (an LPO-level item) is now available as Free Flow on SLE and SLT models. The part was previously only included and available with the Bright Accent Package on SLE and SLT models. In addition, the bright rear bumper protector remains part of the Bright Accent Package.
The only other change is the deletion of the LPO-level Interior Enhancement Package, which for the 2019 model year included premium carpeted floor mats and embroidered front row headrests.
Arguably the most noteworthy change to the 2020 GMC Terrain is the addition of the equipment in the Driver Alert Package II as standard on all trim levels. The features are now bundled as part of the GMC Pro Safety package, and include:
- Automatic Emergency Braking
- Forward Collision Alert
- Lane Keep Assist with Lane Departure Warning
- Following Distance Indicator
- Front Pedestrian Braking
- IntelliBeam headlamps
Adaptive Cruise Control is the only feature that doesn’t become standard. Instead, it’s now included in the Driver Alert Package I available on SLE and SLT models and as part of the Advanced Safety Package on Denali models. For the 2019 model year, Adaptive Cruise Control was included and only available with the Driver Alert Package II, which was available only on SLT and Denali models.
In addition, the Driver Alert Package I is now available on SLE and SLT models, while also bundling the other packages (Driver Convenience Package on SLE and Preferred Package on SLT). The Driver Alert Package I now includes:
- Adaptive Cruise Control – Camera
- Lane Change Alert with Side Blind Zone Alert
- Rear Cross Traffic Alert
- Rear Park Assist
- Safety Alert Seat
Finally, the Advanced Safety Package and Comfort Package are now included and only available with Denali Premium Package. For the 2019 model year, the Advanced Safety Package required the Driver Alert Package II, while the Comfort Package was free flow on Denali models.
Mechanically, the 2020 GMC Terrain deletes the aforementioned 1.6L Turbo Diesel LH7 engine option along with the 2.89 final drive ratio. This leaves the 2020 model with two gasoline engine choices:
- 1.5L LYX I4 – turbocharged DOHC engine rated at 170 horsepower and 203 pound-feet of torque
- 2.0L LTG I4 – turbocharged DOHC engine rated at 252 horsepower and 260 pound-feet of torque
The 1.5L is mated to GM’s six-speed automatic while the 2.0L pairs to the new GM 9-speed automatic transmission.
In addition, the 2.0-Liter LTG Turbo I4 engine is no longer available on the SLE (3SA) trim level. Instead, the up-level engine is only offered on SLT and is standard on Denali. The last change is related to the suspension: as GM Authority was first to exclusively report, the unique Premium Suspension on the 2020 Denali now includes an additional valve internal to the struts and shocks that delivers a more refined ride. This is in addition to the existing upgraded urethane spring isolators that reduce road noise over coarse roads.
The final changes to the 2020 GMC Terrain are related to packages. The changes are as follows:
- Black Edition has been renamed to “Elevation Edition”
- Available on SLE and SLT, package includes:
- 19-inch gloss black aluminum wheels
- Darkened front grille
- Black roof side rails
- Black GMC center caps with black GMC lettering
- Black exterior accents
- Black mirror caps
- Black exterior badging
- Available on SLE and SLT, package includes:
- Addition of Denali Premium Package
The current, second-generation GMC Terrain was introduced for the 2018 model year. The 2021 Terrain introduces a refresh (midcycle enhancement) that includes updated front and rear ends, the introduction of a rugged new AT4 trim level, and various other changes, like the addition of an engine auto stop-start defeat switch. We expect the current-generation Terrain to remain on the market at least through the 2023 model year, after which point it will likely be replaced by an all-new model.
