The standard Apple CarPlay and Android Auto smartphone connectivity allow the passengers to connect the mobile phones with the multimedia system. GMC comes with built-in Wi-Fi connectivity and a Wi-Fi hotspot.

What’s New On The 2020 GMC Terrain?

GMC pro safety is now according to the standards. It includes forward-collision warnings, automatic emergency brakes, warring on leaving the lane, assistance to keep in the lane, and automated high beam headlights. A Denali version has front and rear parking sensors with unique suspension tuning.

The GMC Terrain is available in SL, SLE, and SLT, and the Denali form. And it runs from value-oriented to downright posh.

The base SL comes with 17-inch wheels, active noise cancellation, cloth rates, best keyless ignition, two USB ports, Bluetooth connectivity, and a 7.0-inch touch screen.

The Denali trim adds the premium package, which includes other comfort options. The Terrain SLT consists of leather, dual zoned climates controls, 18-inch wheels, upgraded touchscreen, and heated front seats for a significant discount over the Denali.

How Comfortable Is The Terrain?

On the road, the terrain may face regular low-level shocks, vibrations, and jostling on relatively rough surfaces. The front seats are strong but comfortable, and they can hold up well over long road trips, and back seats are relatively firm and flat.

How Is Technology?

Terrain deserves high marks for its advanced technology, the improved mediocre offering of the past models. It has Bose sound system that offers surprising power and the best clarity. The optional system is quite easy to use.

There are six USB ports and a 4G LTE Wi-Fi hotspot with an easy setup. Many safety systems like forwarding collision warnings and lane-keeping have also been introduced in the 2020 GMC Terrain.

How Is Terrain Drive?

The Terrain’s base engine lacks power, and transmission is slow-witted. Powertrain’s focus on the fuel economy eliminates the snappy acceleration. GMC takes 9.3 seconds to reach 60 mph, which not too fast.

Terrain brakes bite smoothly, evenly, and offer a good relationship between the pedal pressure and actual stopping power. The steering is low and a little bit mushy. The steering effort weights up nicely at the highway, imparting more confidence and a sense of stability.

2020 MGC Terrain is capable of balancing on the twisty roads, and the terrain keeps the body roll in check. It is really not a sports car but still provides reasonably high speed at the turns, and GMC remains stable and composed.

2020 GMC Terrain Interior

How Is The Interior?

The terrain’s interior is quite attractive and well configured, but some controls are awkwardly placed. Terrain’s clumsy transmission interface looks less impressive.

Low seat bolsters and wide opening doors should make getting in and out easy for most of the drivers and passengers. You can have plenty of seat adjustments upfront, though the taller drivers may wish for more steering wheel extensions.

The visibility is below the average, and credit goes to the deep dash, which makes it hard to know where the front is. The front side window offers an excellent view as compared to the rear side window.

  • Number Of Seats

The 2020 GMC Terrain has two rows with five seats. The front seats match the class standard concerning cushioning and spaces. You can also boos the comfort of this are by optional power adjustments. The heated seats let you choose if you just want to warm the bottom cushion, or base and seatback together.

The back seat does not have legroom. And the seats do not slide or recline. Space is enough, and two adults can relax in the back very quickly. But the shoulder room is not spacious for three large passengers. The heated rear seats are optional.

  • Interior Quality

The terrain has an upscale air inside, especially for the upper-level SLT and Denali trims. The build-up quality is good enough, and most of the materials used are of premium quality, though you may also find a few hard plastic pieces too.

  • Terrain Cargo Space

2020 GMS Terrain has 29.6 cubic feet spaces behind the rear seats and 63.3 cubics with the back seat folded. The front passengers can fold the seat flat, which is very helpful for hauling large items. And a hands-free liftgate is also available.

  • Terrain Infotainment, Bluetooth, And Navigation

The GMC infotainment system is very user-friendly. The interface is quite simple, and it comes standard with Apple CarPlay and Android Auto, making it very easy to sync your smartphones.

There you can get a lot of charging options, and up to six USB ports, including the Type-C. The Wi-Fi hot spot is quite fast, just like the regular cellphone services. But the seven-speaker Bose sound systems are failed to satisfy the customers.

Terrain Performance

2020 GMC Terrain Engine

  • Engine

In 202 GMC Terrain, two engines are available, a 170 horsepower with 1.5 liters, four cylinders, and a 252 horsepower with 2.0 liter four cylinders.

The base engine is passable for around-town driving, and reviewers universally endorse the 2.0 liter as the engine of choice. This engine provides quicker acceleration and is required if you are willing to tow more than 1500 pounds.

  • Terrain Gas Mileage

The models which are equipped with the free 1.5 liters engine get good gas mileage, especially in the city. With the help of this engine, GM Terrain has a fuel economy rating of 26 mpg within the city and almost 30 mpg on the highway.
