2020 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 starting with the ASL and moving through the range-topping Denali. Two turbocharged engines are available. Towing a trailer? Going off-road or through snow? Traction Select makes real-time adjustments to master changing driving conditions. Inside the big roomy cabin all the passenger seats fold flat even the one up front. That means lots of room for lots of things in lots of shapes. And the available hands-free power-programmable liftgate helps make it easier to get to all that space. Your Terrain is packed with other convenient technology too. Apple CarPlay and Android Auto compatibility are standard. So is 4G LTE Wi-Fi hotspot capability. And GMC Pro Safety driver-assist features like Lane-Keep Assist with Lane Departure Warning and Automatic Emergency Braking. 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 packed with technology it comes with up to six USB ports—for five passengers! Apple CarPlay and Android Auto compatibility available 4G LTE Wi-Fi hotspot—it’s all there. So is the available myGMC mobile app which lets you find your Terrain start it lock and unlock the doors even check your gas mileage oil life and air pressure—all from your smartphone. And with standard Keyless Open and Start you don’t even have to get out your key to unlock the doors and start the engine. The GMC Terrain. The smarter compact SUV.
The GMC Terrain is built to help you avoid trouble. Standard GMC Pro Safety features like Automatic Emergency Braking and Lane Keep Assist with Lane Departure Warning help you stay aware and in control. IntelliBeam automatic headlamps help you see what’s out there without blinding oncoming traffic. Available Adaptive Cruise Control uses camera technology to make rush-hour traffic easier available Rear Cross Traffic Alert helps you back up more safely and the available Safety-Alert Seat vibrates whenever your Terrain’s driver-assist features detect danger. The GMC Terrain. The safe compact SUV.
With two turbocharged engines to choose from there’s a GMC Terrain ready to take you just about anyone anywhere. There’s a 1.5-liter inline-four that gives you over 200 pound-feet of torque and up to an EPA-estimated 30 miles per gallon. Or choose the two-liter—it lets you tow up to thirty-five-hundred pounds and still gets up to 28 miles per gallon. No matter which engine you pick all-wheel drive is available. And the Terrain is the only vehicle in its class to offer a standard turbocharged engine with a nine-speed transmission. The GMC Terrain. The funner compact SUV.
