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 2005–09, while GM decided to differ the look of the Chevrolet Equinox with its 2010 Terrain and still use the Theta platform. Early 2010 models have the GM Mark of Excellence logo applied on the sides of the vehicle.

For the 2013 model year, the GMC Terrain introduced the Denali trim which consists of more chrome trim and slightly improved interior quality, the 3.6L SIDI V6 that is shared with the 2012 Cadillac SRX in place of the optional 3.0L SIDI V6, and firmer front struts. The Denali also offers cross-traffic detection, blind-spot warning and a power passenger seat as options. [3]

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. [4]

In 2016, GMC introduced the Terrain Nightfall edition, which replaces 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 comes with revised rims with machined faces and black spokes. The Terrain Nightfall trim is available on the SLE-2 and SLT trim levels and is available only in Onyx Black, Summit White, Graphite Gray, and Crimson Red. [5]


The first generation Terrain is 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 in 2013:

In 2013, Nat G CNG Solutions in Houston, TX and AGA Systems in Salt Lake City, UT announced that they had begun offering a Compressed Natural Gas (CNG) version of the Terrain and the Chevy 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. [6]

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 has an 837-mile combined gasoline / natural gas (9.2 gge of CNG) while the passenger version has a 775-mile combined highway range (6.8 gge of CNG).

The companies claimed that the natural gas version had tested at the EPA lab at 31 mpg highway on natural gas and had achieved a Bin 3 emissions equivalent to the Toyota Prius. [6]

Silver Eagle Distributors, L.P., the nation's largest distributor of Anheuser-Busch products, [7] was the launch customer for the natural gas version with an initial order of up to 100 of the natural gas versions.

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 will adopt new front and rear end styling with LED headlamps and tail-lamps similar to that of the fifth generation GMC Yukon and Yukon XL, refreshed interior, new exterior colors, new AT4 trim level, addition of the engine auto stop-defeat switch, and the addition of a new Head-up display. In addition to these updates, GMC discontinued the Terrain's optional diesel-powered engine. [9]

The vehicle was initially planned to go on sale in mid-2020 as 2021 model year vehicle but General Motors cancelled the GMC Terrain facelift in March 2020, due to production issues and declining demand to launch redesigned and facelifted vehicle models in 2020 as 2021 MY vehicles, as a result of the 2020 economic recession caused by the COVID-19 pandemic. General Motors confirmed that the GMC Terrain refresh will instead go on sale in Summer 2021 as 2022 model year vehicle along with refreshed versions of the Chevy Equinox, Chevy Traverse, and Buick Enclave.
