2018 GMC Terrain Review

Want a big helping of technology to go with your compact SUV? Look no further than the GMC Terrain. It comes with a side of turbocharged power and room for five. Choose from four models: SL SLE SLT and the rang-topping Denali. Three turbocharged engines are available—two gas and one diesel. Towing a trailer? Going off-road or through snow? GMC’s Traction Select System delivers increased traction and control. The Terrain’s Electronic Precision Shift System uses buttons to control the transmission—no bulky shifter in the center console means more space to put stuff. And all the passenger seats fold flat even the one up front. That means lots of room for lots of things in lots of shapes. Need to make a phone call? Apple CarPlay and Android Auto compatibility are standard. So is a 4G Wi-Fi hotspot capability. And Teen Driver parental controls. Driver-assist features like lane-keep assist and surround-vision are available too. Choose from a variety of colors options and accessories and build a Terrain that’s all yours. The GMC Terrain. The professional-grade compact SUV.
The GMC Terrain is so loaded with technology it comes with up to six USB ports—for five passengers! Apple CarPlay Android Auto compatibility 4G Wi-Fi hotspot capability—it’s all standard. So is the myGMC mobile app which lets you start your Terrain lock and unlock the doors find it in a parking lot and more—all from your smartphone wherever you happen to be. And with keyless entry you don’t even have to get out your key to unlock the doors and start the engine. The GMC Terrain. The smart compact SUV.
The GMC Terrain is built to protect you. Its body structure uses high-strength steel to help prevent penetration into the passenger compartment. Six airbags form an inflatable cocoon around you and your passengers. Collapsible pedals protect the driver’s legs from injury. The Teen Driver system lets parents set driving parameters—and generates a report card that shows what their kids are doing behind the wheel. And of course driver-assist features like lane-keep assist and surround-vision are available too. The GMC Terrain. The safer compact SUV.
With three turbocharged engines to choose from there’s a GMC Terrain ready to take just about anyone anywhere. A 1.6-liter turbodiesel maximizes efficiency and a two-liter gas engine lets you tow up to thirty-five-hundred pounds—and gets up to 28 miles per gallon on the highway. No matter which engine you pick selectable all-wheel drive is available. Use the Traction Select System to choose all-wheel-drive mode when you need it—or to disconnect the back wheels when you don’t. The GMC Terrain. It’s the smart compact SUV.
