2021 GMC Terrain Vs. 2021 Honda CR-V: How Do They Compare?

The GMC Terrain and Honda CR-V have similar starting prices for base front-wheel-drive models, but the CR-V is more efficient: Its EPA rating is 30 mpg combined, while the Terrain is rated 27 mpg. Both small SUVs have relatively firm suspensions, but the Terrain’s ride quality feels more refined. With the Terrain’s addition of more active-safety features last year, the two SUVs are more similar in this all-important area. The CR-V does have standard adaptive cruise control, however, which is optional on the Terrain. 

Should I Buy the 2021 GMC Terrain?

If you’re looking for a refined, versatile compact SUV with an easy-to-use multimedia system, the Terrain is worth a look. Last year’s addition of more  standard active-safety features enhances its overall value in the very crowded small SUV class.

Grea4 mileage and comfort

Bought it used. The shifter on the dash takes getting used to. But after a month I no longer grab for the shifter arm. Have been happy with comfort. Driving. Gas mileage. Would recommend it.


Stick to fresh tarmac

Rented it for two weeks in Hawaii. Drives and handles well as long as the tarmac is perfect. As soon as you hit ANY imperfections, bumps, cracks or potholes - or heaven forbid an unpaved road - it becomes an absolute disaster. Never seen anything as bad as this one. My stiffened Civic Si is more comfortable. An F.


Try this SUV before you buy another!

Frank Kent in COrsicana, TX gave me a great deal on my trade-in and on my new Terrain! I was intending to by a VW Taos that morning but when I saw the Terrain AT4 and drove it a little, GAME OVER ! I came home in the stylish and comfortable AT4.
