Tech Spec: 2018 GMC Terrain

GMC redesigned its premium compact SUV for the 2018 model year. The all-new SUV features the widest range of choices yet, with three all-new available turbocharged propulsion systems, including a new turbo-diesel. Two new efficiency-enhancing nine-speed automatic transmissions are matched with the gas engines.

The new Terrain’s exterior features stronger, sharper and more sculpted elements such as the grille and lighting features. The all-new Terrain Denali features its signature chrome grille along with Denali-specific accents including body-color fascias and lower trim, plus chrome roof rails, door handles, side mirror caps and body-side molding. Additionally, LED headlamps and 19-inch ultra-bright machined aluminum wheels are standard on the Denali.

All other models feature signature LED daytime running lamps and tail lamps. Bi-functional HID headlamps are standard on SL, SLE and SLT. Additionally, 17-inch wheels are standard on SL and SLE, with 18-inch wheels available on SL and SLE, and standard on SLT.

A range of three all-new turbocharged engines, includes an all-new 1.6L turbodiesel. The new 1.5L and 2.0L turbocharged gas engines are matched with two unique nine-speed automatic transmissions, with the 2.0L turbo engine offering stronger acceleration and a higher degree of performance than its 1.5L counterpart.

GMC’s new Electronic Precision Shift enables more storage room in the center console by replacing the conventional transmission shifter with electronically controlled gear selection consisting of intuitive push buttons and pull triggers.

The Terrain comes standard with GMC’s driver-controllable Traction Select system, which has choices for different driving conditions. Elements such as the throttle responses are optimized for the selected driving mode. AWD models include a FWD mode that disconnects the AWD system to minimize drag and optimize fuel economy, while the AWD mode offers all the benefits of an active AWD system.

Elements such as authentic aluminum trim, soft-touch materials on the instrument panel and doors and standard active noise cancellation are premium features seamlessly integrated into the interior design for a luxurious customer experience.

The Terrain Denali features a new interior with a unique trim tint color and Denali-specific logos and piping on the front seats. Denali customers will benefit from additional standard features, including a heated steering wheel, navigation, Bose premium 7-speaker sound system and a hands-free programmable power liftgate.

GMC keeps passengers connected with 7- and available 8-inch-diagonal infotainment systems, featuring compatibility with Apple CarPlay and Android Auto functionality and a standard OnStar 4G LTE Wi-Fi hotspot that can accommodate up to seven mobile devices. Owners can also manage their vehicles remotely with the myGMC mobile app via their compatible smartphones.

Every new Terrain comes standard with five years of the OnStar Basic Plan at no additional cost. Among other benefits, this connectivity plan features OnStar Smart Driver, an opt-in service designed to help GMC owners maximize their vehicle’s overall performance, reduce wear and tear, monitor fuel efficiency and become better drivers.

An expanded range of available active safety technologies is designed to enhance driver awareness and even help make it easier to park and maneuver in low-speed situations. The features include radar- and camera-based adaptive technologies that can provide alerts to potential crash threats, allowing the driver to react and make changes to potentially avoid them, including: new surround vision; new forward collision alert with following distance indicator; new low-speed forward automatic braking; new lane keep assist with lane departure warning; lane change alert with side blind zone alert; rear cross traffic alert and new safety alert seat.

The new Terrain also features GMC’s new Rear Seat Reminder and Teen Driver. Rear Seat Reminder alerts drivers to check the back seat as they exit their vehicles under certain circumstances, while Teen Driver allows parents to set controls and review an in-vehicle report card in order to help encourage better driving habits, even when adults are not in the vehicle.

Servicing the 2018 GMC Terrain

When the Terrain’s “Change Engine Oil Soon” message displays, the engine oil and filter should be changed within the next 600 miles (1,000 km). If driven under the best conditions, the engine oil life system may not indicate the need for vehicle service for up to a year. The engine oil and filter must be changed at least once a year and the oil life system must be reset.

On vehicles with diesel engines, it is recommended to drain the diesel fuel filter of water when the oil is changed or when the “Water in Fuel Contact Service” message displays.
