GMC Terrain remains a favorite in the compact crossover segment, introducing drivers to the brand's professional grade design and features in a well-appointed vehicle. Terrain Denali delivers an extra touch of luxury with exceptional style and the latest technologies.
In 2015, the Terrain lineup focuses on helping drivers stay connected in their busy lives with two new features, including new OnStar with 4G LTE and standard built-in Wi-Fi hotspot, which provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a three-month/three-gigabyte data trial.
Rounding out the new features are two exterior colors: Dark Sapphire Blue Metallic and Cypress Green Metallic.
The 2015 Terrain features power and efficiency highlighted by the standard Ecotec 2.4L four-cylinder engine with direct injection and camshaft phasing to optimize performance and fuel efficiency – enabling EPA-rated 32 mpg on the highway (FWD models). An available 3.6L V-6 engine with direct injection and continuously variable valve timing is SAE certified at 301 horsepower (224 kW) and 272 lb-ft (369 Nm) of torque.
Terrain is offered in front-wheel-drive and all-wheel-drive models, in SLE and SLT trim levels, as well as the Denali. All models include four-wheel disc brakes with StabiliTrak electronic stability control and traction control, as well as six standard air bags: dual frontal air bags, head curtain side air bags and pelvic/thorax seat-mounted side air bags.
Terrain exterior features
A bold exterior design sets Terrain apart from other midsize crossover vehicles on the road with a refined, sculpted body that is accented with a sleek, yet angular, appearance. Eighteen-inch chrome clad aluminum wheels (standard on SLT-2 and available on SLE-2 and SLT-1 models) and 17-inch aluminum wheels (on SLE and SLT-1 models) emphasize a powerful stance, while chrome details add another level of style.
Terrain's exterior colors for 2015 include Dark Sapphire Blue Metallic, Cypress Green Metallic, Silver Sky Metallic, Quicksilver Metallic, Crystal Red Tintcoat, Carbon Black Metallic, Summit White, Champagne Silver Metallic, Onyx Black and Iridium Metallic. Terrain Denali is offered exclusively in Quicksilver Metallic, Crystal Red Tintcoat, Carbon Black Metallic, Summit White and Iridium Metallic.
Terrain interior features
Inside the Terrain's spacious cabin, premium interior features have been designed with high standards of functionality and materials that exude a commanding and structured feel. From the warm ambient lighting to the contrast stitching details, the Terrain is home to many comfort and convenience controls that make driving this vehicle seem effortless.
The standard and segment-exclusive MultiFlex sliding rear seat can be moved fore or aft nearly eight inches (200 mm), providing increased passenger comfort – including 39.9-inches (1,013mm) of legroom – or greater rear cargo capacity, while the 60/40-split rear seatback offers additional configurations for passengers and cargo. The rear cargo area offers 31.6 cubic feet (894 liters) of storage, as well as one of the Terrain's four auxiliary power outlets.
Interior color choices for 2015 include Jet Black, Light Titanium and Brownstone. Terrain Denali is offered exclusively in Jet Black.
IntelliLink and OnStar 4G LTE
GMC IntelliLink combines with OnStar to bring segment-exclusive infotainment technology to Terrain at a time more and more consumers are buying smartphones. IntelliLink extends the OnStar experience from safety and security to information and entertainment by seamlessly integrating the capability of a smartphone into the vehicle so that hand-held phones may be safely stowed while driving.
Text Messaging Alerts and Siri Eyes Free features aid drivers with the latest in technology. With Text Messaging Alerts, the driver can be alerted to new messages and can have them read aloud, view and respond to them (functionality depends on the smartphone). Siri Eyes Free enables iPhone4S and iPhone 5 users to access Siri via the steering wheel controls and check calendar entries, have text messages read and respond to them, place calls or call up music.
Android phone users can also use the steering wheel controls to access their phone's voice recognition features.
GMC's Color Touch navigation radio features a touch-screen control that incorporates all of the IntelliLink features and more. It is available on SLE-2, SLT models and Terrain Denali. SiriusXM Satellite Radio (with three-month trial period) is standard on all models.
Complementing IntelliLink to enhance Terrain's connectivity is new OnStar with 4G LTE and standard built-in Wi-Fi hotspot. It provides a mobile hub for drivers and passengers to stay connected. The hotspot is on whenever the vehicle is on and comes with a three-month/three-gigabyte data trial.
4G LTE is the most current and fastest mobile data network – 10 times faster than 3G and 100 times faster than the previous generation of OnStar hardware. And with OnStar, it also offers stronger, broader coverage than smartphones on the same network and it's easy to use: If the vehicle is on, the connection is on.
At the time of purchase, six months OnStar Directions and Connections includes all of OnStar's advisor-based safety and security features, including Automatic Crash Response and Stolen Vehicle Assistance, as well as turn-by-turn navigation.
Five years of OnStar Basic Plan includes RemoteLink Key Fob Services, allowing owners to remotely start and lock/unlock a car (if properly equipped), and activate the horn and lights from anywhere with a data connection. It also includes OnStar Vehicle Diagnostics, which runs monthly checks of a vehicle's engine, transmission, anti-lock brakes and more, and Dealer Maintenance Notification, which sends diagnostic report directly to a preferred dealer to simplify service scheduling.
GMC Terrain's standard Ecotec 2.4L engine and available 3.6L V-6 feature fuel-saving direct injection and continuously variable valve timing. The 2.4L delivers 182 horsepower (136 kW) with an EPA-estimated highway fuel economy rating of 32 mpg (FWD models).
The 3.6L is rated at 301 horsepower (224 kW) and 272 lb-ft of torque (369 Nm) and uses lightweight components that contribute to the Terrain's fuel efficiency while boosting horsepower. An integrated cylinder head/exhaust manifold design saves about 13 pounds compared to a non-integrated design, while a composite intake manifold saves about 5.5 pounds vs. an aluminum intake. Additionally, a lightweight structural front cover and high-strength connecting rods save additional weight.
An efficient six-speed automatic transmission is standard on all models and an "Eco" transmission mode on 2.4L-equipped models alters shift points to improve fuel economy.
Chassis and suspension
Terrain engineers have ensured a smooth, quiet ride by building on a body-integral structure with single-piece body side stampings and targeted applications of high-strength steel. The strong structure supports a four-wheel independent suspension system that – with a long, 112.5-inch (2,857 mm) wheelbase and wide front and rear tracks – contributes to car-like ride and handling traits. The long wheelbase and wide tracks reduce body roll for a more stable driving experience.
