Used 2020 GMC Terrain SUV Trims Comparison

Standard equipment highlights for the base SL include power-adjustable heated mirrors, rear privacy glass, keyless entry and ignition, a 7-inch touchscreen, Apple CarPlay and Android Auto compatibility, and a six-speaker sound system. A host of advanced driver safety aids, including low-speed forward collision warning with automatic emergency braking, are also standard.

The midlevel SLE furnishes just a few extra standard features but opens up access to a few appealing option packages (notably, the Driver Convenience, Infotainment I and Driver Alert I packages) that add a variety of convenience and safety-related features.

Stepping up to the SLT trim gets you leather upholstery and some of the SLE's optional features, such as the 8-inch touchscreen, power driver's seat and dual-zone climate control. You can also get even more options here, including a power-adjustable front passenger seat and a heated steering wheel.

At the top of the Terrain range is the Denali, which receives unique styling cues and interior trim as well as most of the optional features from the above trim levels. A new optional Denali Premium package tops it all off with features such as ventilated front seats, adaptive cruise control and a surround-view parking camera system.
