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.

So far so good

So far this vehicle is meeting all my expectations and I feel it will for years to come. Looking forward to many road trips in comfort and style


Only had vehicle for a short time . Satisfied

I love the vehicle. Only problem is I don’t have a cargo net in the trunk which I have had in all other vehicles I have owned. Very highly needed and recommend for grocery shopping or holding small packages in place



It’s great some more perks would be nice but great for what it is! Love all the update amenities, remote access as well as the app!
