Full Description: 2018 GMC Terrain compact crossover SUV has not been redesigned since. Mechanically identical to the Chevrolet Equinox, 2018 GMC Terrain has adopted an even more masculine demeanor with the addition of a Nightfall edition. Sharp body lines and creased features make the boldly square-jawed Terrain stand out. Not everyone favors the rough-and-ready look, but its brash design definitely makes an impression, whereas many crossovers blend into each other. GMC Terrain SLT offers a choice between a fuel-efficient four-cylinder engine that makes 252 horsepower. The direct-injected, 1.5-liter four-cylinder is a familiar GM workhorse of an engine. Earning good marks in both ride and handling, GMC Terrain SLT competes against a host of compact crossovers, including the top-ranked, strong-selling Honda CR-V and Toyota RAV4. Apart from poor rearward visibility, the Terrain comes across as a viable contender, and the rearview camera that comes standard helps alleviate those obstacles to clear vision. Some blind spots are caused by the Terrain's fixed back-seat headrests, which cannot be folded down or removed. We recommend opting for rear parking sensors. On the safety front, the Insurance Institute for Highway Safety gave the Terrain Good scores in all crash-tests, including the difficult frontal small-overlap collision. As a result, it was named a Top Safety Pick. Meanwhile, the National Highway Traffic Safety Administration gave the Terrain a four-star overall crash-test rating, including four stars for frontal-impact protection and five stars for side-impact. Terrains can be equipped with some of the latest safety technology, including blind-spot monitoring with rear cross-traffic alert, lane-departure warning, and forward collision alert. The GMC Terrain SLT Nightfall edition package adds a charcoal grille with black accents and surround, black 19-inch wheels, black front/rear fascia accents, including black luggage rails. The Nightfall package is offered on Terrain SLT models, with four body-color choices. GMC has been progressing toward crisper lines and sharper looks, and the Terrain reflects that. More squared-edged in its blockiness than the related Chevrolet Equinox, it features a power-dome hood with C-shaped headlights. Upper trim levels add LED running lights. As usual, the top-rung Denali stands out, led by a mesh grille and satin metallic trim. The new Nightfall option adds a blacked-out grille, black wheels, and black front/rear fascias. The cabin is strictly contemporary. Every interior design element is tasteful, in accord with other GMC models, including the larger Acadia. The look is especially notable within the Denali edition, which gets a dark woodgrain-trimmed steering wheel and stitched dashboard pad, along with premium leather. On the dashboard, low-gloss metallic trim surrounds a shield-shaped set of controls. A hooded 7-inch touchscreen controls the infotainment system. The center console is wide, while the large glovebox is deep. Four-cylinder is fine for families that need urban transportation or lean toward long-distance cruising. Four-cylinder models use electric power steering. The 2018 .GMC Terrain SLT is quite spacious inside for a compact crossover. Terrain's distinctive square lines appeals to buyers who favor a traditional SUV look. The four-cylinder is the preferred choice for fuel economy.Air filtration, Front air conditioning: automatic climate control, Front air conditioning zones: dual, Humidity/dewpoint sensors, Rear vents: second row, Airbag deactivation: occupant sensing passenger, Front airbags: dual, Side airbags: front, Side curtain airbags: front / rear, Side-curtain airbag rollover sensor, Antenna type: diversity / mast, Auxiliary audio input: Bluetooth / USB / iPod/iPhone / jack / memory card slot, Internet radio app: Gracenote / Pandora / Stitcher, Radio: AM/FM / touch screen display / voice operated, Radio data system, Satellite radio: SiriusXM, Speed sensitive volume control, Total speakers: 6, Watts: 80, ABS: 4-wheel, Braking assist, Electronic brakeforce distribution, Electronic parking brake: auto off, Front brake diameter: 11.8, Front brake type: ventilated disc, Power brakes, Rear brake diameter: 11.3, Rear brake type: disc, Armrests: rear center with cupholders / rear folding, Floor mat material: carpet, Floor material: carpet, Floor mats: front / rear, Steering wheel trim: leather, Ambient lighting, Assist handle: front / rear, Capless fuel filler system, Cargo area light, Center console: front console with armrest and storage, Cruise control, Cupholders: front / illuminated / rear / 6, Multi-function remote: panic alarm / proximity entry system / trunk release, One-touch windows: 4, Overhead console: front, Power outlet(s): 115V rear / 12V cargo area / 12V front, Power steering, Power windows: lockout button, Push-button start, Rearview mirror: auto-dimming, Remote engine start, Retained accessory power, Steering wheel: tilt and telescopic, Steering wheel mounted controls: audio / cruise control / multi-function / phone / voice control, Storage: bin / door pockets / front seatback / sunglasses holder, Tool kit, Vanity mirrors: dual illuminating, Liftgate window: fixed, Rear door type: liftgate, 4WD selector: electronic, 4WD type: part time, Axle ratio: 3.47, Center differential: mechanical, Drive mode selector, Auto start/stop, Battery: maintenance-free, Battery saver, Active grille shutters, Door handle color: body-color, Exhaust tip color: stainless-steel, Front bumper color: body-color, Grille color: black with chrome accents, Mirror color: body-color, Rear bumper color: body-color, Rocker panel color: black, Window trim: black, Infotainment: Android Auto ready / Apple CarPlay ready / IntelliLink, Infotainment screen size: 8 in., Clock, Compass, Digital odometer, Driver information system, External temperature display, Fuel economy display: MPG / range, Gauge: tachometer, Instrument cluster screen size: 4.2 in., Multi-function display, Oil monitor, Trip computer, Trip odometer: 2, Warnings and reminders: low fuel level / maintenance due / tire fill alert, Daytime running lights: LED, Front fog lights, Headlights: HID/Xenon / auto delay off / auto on/off, Taillights: LED / rear center, Side mirror adjustments: manual folding / power, Side mirrors: auto-dimming / heated / integrated turn signals, Roof rails, Roof rails color: silver, Camera system: rearview, Check rear seat reminder, Child safety door locks, Child seat anchors: LATCH system, Programmable safety key, Rearview monitor: in dash, Steel body panels, Emergency locking retractors: front / rear, Front seatbelts: 3-point, Rear seatbelts: 3-point, Seatbelt pretensioners: front, Seatbelt warning sensor: front, Driver seat: heated, Driver seat power adjustments: height / lumbar / reclining / 8, Front headrests: adjustable / 2, Front seat type: bucket, Passenger seat: heated, Passenger seat manual adjustments: reclining / 4, Rear headrests: adjustable / 2, Rear seat folding: split, Rear seat manual adjustments: reclining, Rear seat type: 60-40 split bench, Upholstery: leather-trimmed, Upholstery accents: perforated, 2-stage unlocking doors, Anti-theft system: alarm with remote / engine immobilizer / theft-deterrent system, Power door locks: anti-lockout / auto-locking, Hill holder control, Stability control, Traction control, Front s
