2020 GMC Terrain Interior Review


Interior: 7.3

The GMC Terrain has numerous advanced safety features that are newly standard for 2020. These join a nicely equipped infotainment system that is easy to use.

Most of the Terrain’s trim levels are premium-grade: nicer than many other rivals in this affordable class but not quite as posh as a luxury vehicle's. Space is plentiful for passengers. Cargo space is below average behind the seats, but with its fold-flat front seat, the Terrain's maximum amount of room is generous and highly functional.

  • The Terrain's interior is attractive and well-configured, but some controls are awkwardly placed." -- Edmunds
  • A few hard plastics in the lower areas of the dashboard and doors are reminders that this is a mainstream, not luxury, marque. The embroidered headrests and stitched dashboard covering in the Denali bring an upscale air, though." -- Kelley Blue Book
  • "Inside, GMC paid extra attention to what the driver touches and interacts with. Occupants are treated to soft hewn leather, supremely cushiony seats, the newest version of GM's infotainment system … and interior space for days." -- Automobile Magazine (2018)


The two-row Terrain comes with five seats. On a day's drive, a quartet of adults will find the accommodations to be relaxing, especially with the Terrain's generous amount of rear-seat legroom. The passenger areas are otherwise ordinary for the compact SUV class: no major complaints, but no elements that qualify as class-leading.

Cloth upholstery, four-way manually adjustable front seats, and a fold-flat rear seat with a 60/40 split are standard. Seating options include leather upholstery, an eight-way power-adjustable driver’s seat, a six-way power-adjustable front passenger seat, heated front seats, ventilated front seats, heated rear seats, and a heated steering wheel.

For securing child safety seats, the Terrain has two complete sets of LATCH connectors for the rear outboard seats, as well as an upper tether for the rear middle seat.

  • Low seat bolsters and wide-opening doors should make getting in and out easy for most drivers and passengers. There's also plenty of seat adjustment up front, although taller drivers might wish for more steering wheel extension. Visibility is below-average thanks to a deep, angled dash that makes it hard to know where the front really is." -- Edmunds
  • "Like most of the competition, the 2019 Terrain's cabin is perfectly functional and comfortable without necessarily being that luxurious." -- Kelley Blue Book (2019)
  • "There is plenty of room for passengers in both rows. The front seats are comfortable, and I spent more than an hour in the second row – my six-foot two-inch frame found those accommodations equally as pleasing with … plenty of headroom and a fair amount of room for my legs. No complaints." -- Forbes (2018)

Interior Features

The Terrain's infotainment system is very easy to use thanks to its straightforward interface, quick responses, and standard Apple CarPlay and Android Auto. The base unit includes a 7-inch touch screen, four USB ports (including Type-C), Bluetooth, a Wi-Fi hot spot, and six speakers. Proximity keyless entry and push-button start are also standard.

A couple upgraded infotainment systems are available. These include upgrades such as an 8-inch touch screen, satellite radio, HD Radio, and navigation. Other optional features include a seven-speaker Bose audio system, a 110-volt household-style power outlet, wireless device charging, dual-zone automatic climate control, and remote start.

The Terrain's standard safety features expand significantly for 2020. In addition to forward automatic emergency braking, forward collision warning, lane keep assist with lane departure warning, a following distance indicator, front pedestrian braking, and automatic high-beam headlights, every model comes with a rearview camera and Teen Driver. This system lets you do things like set speed and audio volume limits for secondary drivers, as well as monitor their driving performance.

GMC offers numerous safety upgrades, though some are only available as options in the Denali trim. The upgrades include GM's safety alert seat, which vibrates to alert you of potential hazards. Also available are blind spot monitoring, rear cross traffic alert, lane change alert, adaptive cruise control, adaptive headlights, a surround-view parking camera system, front and rear parking sensors, and an automated parking system.

  • "The Terrain deserves high marks for its tech, improving on the mediocre offerings of past models. The optional Bose sound system offers surprising power and clarity, and the optional navigation system is easy to use. Apple CarPlay and Android Auto come standard and beat GMC's native software for ease of use, but the standard system works fine for those outside the Apple/Android ecosystem." -- Edmunds
  • "Above the shift buttons sits a new infotainment system that acts a lot like a smartphone, with scrolling capability and pinch-and-zoom maps. By rearranging the main map screen, GMC made it easier to access important functions such as the option to cancel the current route or change the volume of the voice turn-by-turn directions." -- Motor Trend (2018)
  • "I like the Intellilink infotainment system (7-inch screen), which is fast and intuitive, and all of the instrumentation is comprehensive and easy to read (and use). There is plenty of power for connected devices (both USB and 12-volt)." -- Forbes (2018)


The Terrain doesn't have a lot of cargo space for a compact SUV, but it does come with one feature few rivals have: You can fold the front passenger seat flat to expand your hauling options.

With every seat in place, there is 29.6 cubic feet of cargo space. The Terrain has 63.3 cubic feet with the rear seats folded and 81 cubic feet if you also fold the front passenger seat. A hands-free power liftgate is available.

  • With the rear seats folded, the Terrain's 63 cubic feet of cargo space lags behind class benchmarks (Honda CR-V and Toyota RAV4). But a fold-flat front passenger seat is a nice touch (surfers and campers, rejoice) and increases space to 81 cubic feet. A power liftgate and low liftover height make cargo loading easy, too." -- Edmunds
  • The rear seats don't slide or recline, but the front seatback folds down for some extra cargo versatility." -- Kelley Blue Book
