2020 GMC Terrain Review

Name: 2020 GMC Terrain Review
Brand: GMC

Price Range: $13,730 - $28,590

The redesigned 2020 GMC Terrain has a nicer interior, more room, enhanced utility, and better tech than its predecessor. But a weak base engine, unresponsive transmission and bouncy ride, paired with a high price, hinder the Terrain from standing out in the competitive compact-SUV class.

2020 GMC Terrain SLT 4dr SUV (1.5L 4cyl Turbo 9A)

I drive a CRV at work all day in all kinds of Phoenix metro traffic. It is OK but my 2020 Terrain has it beat overall in my opinion. The 2.0 turbo is zippy, and quiet. I drove a 2020 1.5L turbo up to Flagstaff and I would recommend the bigger engine, glad I bought it. The CRV and its CVT transmission is loud and annoying on the freeway. Hard to keep a consistent speed on the freeway …

2020 GMC Terrain SLT 4dr SUV AWD (1.5L 4cyl Turbo 9A)

As a current Terrain owner (AWD SLT 2.0), I am perplexed as to what vehicle Edmunds actually drove? My Terrain is a perfect balance of sport and luxury along with making terrific gas mileage as a daily driver. I guess the 1.5 turned them off to the point that they lowered all of the other categories to reduce the score. Seems ridiculous to get bent out of shape over an engine designed …

2020 GMC Terrain Denali 4dr SUV (2.0L 4cyl Turbo 9A)

Literally I don't know what Edmunds reviewed -- I recently checked out all the small-mid SUV's at the LA auto show and was surprised to find the Terrain to my liking. My brother has a CX-5 which is very nice, good materials and it drives quiet and handles well, but just feels cramped up front for me (6ft, 240lb guy). It feels roomier than most competitors including CX-5, has decent …

2020 GMC Terrain SLT 4dr SUV AWD (1.5L 4cyl Turbo 9A)

What we like: We loved the Terrain SLT we purchased a few years ago, so in the early fall, with $8,000 in incentives, we traded it in for a 2020 model. This is a very SMART car. Lots of new features and technology to learn. We like that it allows data from the cell phones to download to the car. Nice to set up your Google Maps or Waze, go out to the car and view it on the display …
