    If you’re looking for something manageable yet specious, a small SUV is worth looking into. Small SUVs are sought out for their safety, fuel economy, and all-weather capabilities. They’re a happy medium where you get a little bit of everything; space, power, and affordability. Oftentimes, these smaller SUVs come with 4-cylinder engines. They’re also lighter, which helps their mileage and aids in their winter road performance. Their all-wheel drive capability tops off their off-roading powers, being much safer than most cars, especially in detrimental weather. This is where vehicles like the 2021 GMC Terrain fit in.

    The 2021 Terrain comes in 4 different trims, with the beloved Denali trim coming as a late availability. The lowest trim, the SL, is front-wheel drive only, which helps it get up to 30 miles per gallon. With one impressive engine powering every model, the Terrain is equipped to take you anywhere. Despite its smaller size, it still can seat 5 passengers, and it offers up to 63.3 cubic feet of cargo space. This small SUV has a lot to offer, and we’re excited to tell you about all its capabilities.

  • Performance

    Plenty of Power With One Engine

    Performance is everything, right next to safety. This small SUV comes with a 1.5-liter turbocharged 4-cylinder engine that produces 170 horsepower and 203 lb-ft of torque. You will find this engine paired with a responsive 9-speed automatic transmission. On top of this, it can even tow up to 1,500 pounds if properly equipped, so you can bring along some extra cargo.

    Except for the base trim SL that is front-wheel drive only, you can get the 2021 Terrain in front-wheel drive or all-wheel drive. Front-wheel drive is the perfect option if you want to get the most out of the Terrain's fuel economy. On the other hand, if you live in a rural area with choppy roads or in an area that receives a decent amount of inclement weather, you'll want to upgrade to the all-wheel drive for better traction and control.

    Fuel Economy

    With only one excellent engine powering this SUV, you're not going to see much of a range in fuel economy. Front-wheel drive models will get around 25 miles per gallon in the city, 30 miles per gallon on the highway, and 27 miles per gallon combined. Meanwhile, the all-wheel drive models will get an estimated 25 miles per gallon in the city, 28 miles per gallon on the highway, and 26 miles per gallon combined. This small SUV has the perfect amount of power and fuel economy to make it fit with almost any driver's needs.
