our expert's take

What Is the 2021 GMC Terrain?

The GMC Terrain is a compact SUV that seats five. It’s powered by a 170-horsepower, turbocharged 1.5-liter four-cylinder engine that works with a nine-speed automatic transmission. Front-wheel drive is standard, and all-wheel drive is available. Competitors include the Honda CR-V, Mazda CX-5 and Volkswagen Tiguan

What’s New on the 2021 GMC Terrain?

There are no significant changes this year. 

What Features in the 2021 GMC Terrain Are Most Important?

Standard features include:

  • Push-button start
  • 4G LTE Wi-Fi hot spot (data subscription required after trial)
  • 7-inch touchscreen multimedia system
  • Apple CarPlay and Android Auto smartphone connectivity
  • Forward collision warning 
  • Automatic emergency braking

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.
