GMC Terrain

The GMC Terrain is a crossover SUV by American manufacturer General Motors under its GMC marque. Sharing its platform with the Chevrolet Equinox, the first-generation Terrain was built on GM's Theta platform, while the second-generation model is currently built on the Delta platform. The Terrain is the smallest GMC vehicle, slotted below the Acadia. It also indirectly replaced the Pontiac Torrent which was typically sold via the same dealers prior to General Motors dropping the Pontiac brand.

First generation (2010)
The 2010 Terrain debuted in April 2009 at the New York International Auto Show, introduced as a replacement for the Pontiac Torrent, which ended production after GM shut down the Pontiac brand in 2010. Although the preceding Pontiac Torrent had the same Theta platform, the Torrent was a rebadged version of the original Chevrolet Equinox from 2005 to 2009, while GM decided to differ the look of the Chevrolet Equinox with its 2010 Terrain and still use the Theta platform. Early 2010 models had the GM Mark of Excellence logo applied on the sides of the vehicle.

The Terrain initially came in SLE and SLT trims. For the 2013 model year, a Denali trim was added, featuring additional chrome trim and slightly improved interior quality, the optional 3.6-liter SIDI V6 that is shared with the 2012 Cadillac SRX, and firmer front struts. The Denali also offered cross-traffic detection, blind-spot warning, and a power passenger seat as options. A low-end SL trim was added for 2015, which was only available with front-wheel drive and the 2.4L Ecotec engine.

2016 refresh
For 2016, the GMC Terrain received a facelift as part of its first mid-cycle refresh along with the Equinox. The refresh consisted of new front and rear fascias, new grille, a power dome hood, LED daytime running lights, new wheels, a new gear selector, a second storage shelf under the dashboard, as well as deletion of the door lock buttons from the dashboard.

For 2017, GMC introduced the Terrain Nightfall edition, replacing chrome with gloss-black finish on the grille surround, the front and rear fascia accents, the license-plate surround, mirror caps, and roof rack, as well as charcoal grille inserts and darkened headlights pulled from the Terrain Denali. The Terrain Nightfall came with revised rims with machined faces and black spokes. The Terrain Nightfall trim was available on the SLE-2 and SLT trim levels and was available only in Onyx Black, Summit White, Graphite Gray, and Crimson Red.

Engines
The first-generation Terrain was powered by a choice of two engines, a 2.4-liter 4-cylinder and a V6 engine that was upgraded from 3.0 liters of displacement to 3.6 liters for 2013. Notes:


 * All 4-cylinder models have a single rear exhaust port, while all V6 models have dual rear exhaust ports.
 * All ratings are on regular gasoline.

Natural gas version
In 2013, Nat G CNG Solutions in Houston, Texas, and AGA Systems in Salt Lake City, Utah, began offering a Compressed Natural Gas (CNG) version of the Terrain and the Chevrolet Equinox using the 2.4L Direct Injection engine. The natural gas version is a "bi-fuel" CNG vehicle, meaning it runs on either gasoline or natural gas, giving it extended range. The Terrain/Equinox were the first direct injection natural gas vehicles ever approved by the US EPA.

The CNG version was available for newly purchased Terrains through select dealers or as a retrofit on 2013 and 2014 models. Nat G CNG Solutions offered the vehicle in two options: a two-seater cargo version and a five-seat passenger version. The cargo version had an 837 mi combined gasoline/natural gas highway range (9.2 gge of CNG), while the passenger version had a 775 mi combined highway range (6.8 gge of CNG).

The companies claimed that the natural gas version had tested at the EPA lab at 31 mpgus highway on natural gas and had achieved a Bin 3 emissions equivalent to the Toyota Prius.

Silver Eagle Distributors, L.P., the nation's largest distributor of Anheuser-Busch products, was the launch customer for the natural gas version with an initial order of up to 100 of the natural gas versions.

Recall
In March 2022, General Motors recalled over 740,000 GMC Terrain models made from 2010 to 2017 for headlights being excessively bright. In October 2022, General Motors issued a fix for the recall by thoroughly cleaning the headlights and adding tape on the headlight.

Safety
The 2010 model year Terrain was awarded "Top Safety Pick" by IIHS, it received the highest-possible rollover protection rating of Good and achieved the Good rating for the roof strength test because its roof can withstand a force equal to four times the vehicle's weight.

Second generation (2018)
On January 8, 2017, the second generation GMC Terrain was unveiled at the 2017 North American International Auto Show as a 2018 model. The second generation went on sale in Summer 2017 and was available with three engine choices, and standard features such as a 7-inch touchscreen and LED daytime running headlights and taillights. There is also a more luxurious variant called the GMC Terrain Denali.

2022 refresh
In February 2020, General Motors unveiled a refreshed version of the GMC Terrain; it was initially planned to go on sale in mid-2020 for the 2021 model year, but production issues and the COVID-19 recession led General Motors to cancel the GMC Terrain facelift in March 2020. General Motors confirmed that the GMC Terrain refresh would instead go on sale in Summer 2021 for the 2022 model year along with refreshed versions of the Chevrolet Equinox, Chevrolet Traverse, and Buick Enclave.
