2021 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 SL and moving through the range-topping Denali. Want some efficient power? The Terrain’s turbocharged engine gets up to 30 miles per gallon and can tow up to fifteen-hundred pounds. Going off-road or through snow? Traction Select makes real-time adjustments to keep up with changing conditions. Inside the cabin all the passenger seats fold flat even the one up front. That means lots of space for lots of things in lots of shapes. And with the available Hands-Free Power-Programmable Liftgate it’s easy to get to all that space. Your Terrain is packed with technology too. Apple CarPlay and Android Auto4 compatibility come standard. So do GMC Pro Safety driver-assist features like Automatic Emergency Braking and Lane-Keep Assist with Lane Departure Warning. 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.
