2018 GMC Terrain Review Mar 13, 2017 by Cedric (Driver Weekly)

You will still have to wait awhile to get behind the wheel of the 2018 GMC Terrain Diesel, but in the meantime, you can find out more about it and start looking forward to the expanded lineup. The 2018 Terrain made its official debut at the 2017 Detroit Auto Show when GMC showcased the upcoming changes for the new generation and the new diesel powertrain.



Most vehicles seem to get larger with every consecutive generation, but the 2018 GMC Terrain does the opposite. It has dropped inches, as well as pounds. In our opinion, this was a logical change as the previous model looked square and weighted down as opposed to sleek like its competitors. With the downsizing, GMC was able to give the Terrain more conventional styling that most drivers will prefer. There is now a floating roofline that enhances the more aerodynamic-looking design, but we will have to wait and see what it does to visibility. You will also notice that the lights and grille look more sculpted, while the overall shape shows signs of being tweaked in a wind tunnel. The Denali will boast LED headlights, 19-inch ultra-bright wheels, and plenty of chrome.



If you are curious about the exact figures, the previous Terrain had an 112.5-inch wheelbase and measured 185.5 inches long overall. For 2018, these figures drop to 107.3 and 182.3 inches, respectively. Even with that decrease, the cargo space only goes down 0.3 cubic feet, and we feel that 63.3 cubic feet of storage with the rear seats down is still respectable. The decrease in size pays off with a lower curb weight as well. That should lead to improvements in fuel economy, although we will not have anything to compare it to with the diesel, as this is a new engine.

The Diesel Engine


The most surprising revelation from the 2018 Terrain’s debut is the availability of a diesel engine. This is a 1.6-liter turbodiesel that generates 137 horsepower and 240 pound-feet of torque. It works with a six-speed automatic transmission and can be paired with front-wheel drive or all-wheel drive. People who are not keen on a diesel engine can still choose from a 170-horsepower 1.5-liter turbocharged four-cylinder gas-powered mill and a 252-horsepower 2.0-liter turbo, both of which work with a nine-speed automatic.

Trim and Features


Whether you go with the diesel or stick to a gas engine, the 2018 Terrain lets you choose from four trims in a familiar format, including the SL, SLE, SLT, and Denali. Advanced features abound in this updated model with onboard 4G LTE Wi-Fi, Android Auto, Apple CarPlay, and a seven or eight-inch touchscreen. Further information on features and options will be coming in the very near future. The 2018 GMC Terrain Diesel will be going on sale in the summer. This means that you should not have to wait long to read a review of what it is like to drive this SUV.
