First Generation

The Terrain went on sale for the North America market in 2009 as a 2010 model. The Terrain replaced the Pontiac Torrent compact crossover. It is offered with front-wheel- and all-wheel-drive.

The first-generation GMC Terrain was available from the 2010 through the 2017 model years. The compact crossover was built on the GM Theta platform, the automaker’s first crossover architecture. It also underpinned the discontinued Pontiac Torrent and Saturn Vue, along with the first- and second-generation Cadillac SRX and Chevy Equinox – all compact crossovers. The Vue used the short wheelbase variant and the SRX used the premium variant, while the rest of these models used the long wheelbase variant of the Theta platform.

The 2010 GMC Terrain is powered by GM’s naturally aspirated 2.4L I4 LAF gasoline engine producing 223 horsepower and 172 pound-feet of torque, and an optional naturally aspirated 3.0L V6 LFW gasoline engine producing 265 horsepower and 223 pound-feet of torque.

In 2012, GM’s naturally aspirated 2.4L I4 LEA gasoline engine replaced the LAF, maintaining the same power specs. It is mated to GM’s six-speed 6T45 automatic transmission (MH7 for front-wheel-drive and MHC for all-wheel-drive).

For the 2013 model year, the range-topping Terrain Denali luxury trim debuted. Also, the LFW engine was replaced by the naturally aspirated 3.6L V6 LFX gasoline engine, producing 301 horsepower and 272 pound-feet of torque. It is mated to GM’s six-speed 6T70 automatic transmission (M7W for front-wheel-drive and M7U for all-wheel-drive).

For 2016 the Terrain received a refresh with a completely redesigned grille and new front fascia along with a power dome hood and LED daytime running lights, plus changes to the rear fascia. It also included improvements and quality upgrades to the interior.

For 2017 GMC introduced the Terrain Nightfall Edition, a stylized special edition combining blacked-out exterior details and wheels, plus the addition of popular technologies.

The 2017 Terrain was the last model year of the first generation.

Here’s a list of guides and the model years changes for the first-gen Terrain:

Second Generation

For the 2018 model year, GMC completely overhauled (redesigned and re-engineered) the Terrain, delivering the second generation of the Terrain nameplate after selling the first-generation model for eight years. It is underpinned by the GM D2XX platform, which is shared by the first-generation Buick Envision and Cadillac ELR, second-generation Chevy Equinox, and discontinued Chevy Cruz and Chevy Volt.

The all-new Terrain also represents “the next chapter of GMC design” and brings higher amounts of refinement and versatility to adapt to customers’ unique needs, while packing more available advanced safety technologies than ever before.

The 2018 Terrain is powered by three new engines. This includes GM’s turbocharged 1.5L I4 LYX, producing 170 horsepower and 203 pound-feet of torque, and turbocharged 2.0L I4 LTG, producing 252 horsepower and 260 pound-feet of torque. These are joined by the turbo-diesel 1.6L I4 LH7, producing 170 horsepower and 203 pound-feet of torque. The turbocharged gasoline engines are mated to GM’s nine-speed 9T45 automatic transmission and the turbo-diesel is mated to GM’s six-speed 6T45 automatic transmission.

For 2019, the Terrain gained a new Black Edition package that is distinguished by darkened exterior treatments.

For the 2020 model year of the Terrain, GMC updated and renamed the Black Edition package to the Elevation Edition package. The marque also dropped the turbo-diesel engine.

In 2021, GMC dropped the LTG engine, leaving the LYX as the only remaining powerplant option.

For the 2022 model year – the fifth of the second generation – GMC unveiled the refreshed Terrain, bringing updated exterior styling and a revised cabin to the crossover, along with a new off-road-focused Terrain AT4 trim level. The addition of the AT4 trim level for the Terrain effectively fulfills GMC’s promise to bring an AT4 variant to every model it offers. Also, GMC dropped the base SL trim level. The resulting full Terrain model lineup includes the now SLE base model, SLT, AT4, and Denali.

The Terrain also gains a new Black Diamond Edition package that includes a wealth of content for the exterior and interior. It is only available on the Terrain Denali trim level, and will require Ebony Twilight Metallic exterior paint.

For 2023, the Terrain gains all-new interior trims and the addition of the new Head-up Display feature for SLT and AT4 trim levels, which is standard on the range-topping Denali trim level.

Here’s a list of model year guides and the changes for the second-gen Terrain:
