Consumer Reviews for the GMC Terrain
Read recent reviews for the GMC Terrain
Compared to the CRV...
K squared, 03/23/2020
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 … which drives me nuts. I notice the Terrain has a quieter cabin because I can hear people talk on the phone. I am 6’9 and would always like more legroom but the console of the CRV digs into my right leg, in the Terrain it does not. I am still getting used to no shifter but the extra room is nice. To me the only thing the CRV wins in the comparison is it gets really good gas mileage & it has never been in the shop for a repair in 88,000 miles (1 1/2 years). I hope the Terrain is comparable in that area! Not sure I agree with all the CRV hype and the experts ragging on the Terrain. I like the look of the Terrain and 18/19/20’s look WAY better than its boxy predecessor.
