GMC has pulled the covers off its all-new, 2018 Terrain. It follows the 2018 Chevrolet Equinox into a new generation of GM’s small crossover, with both sharing the same platform, same three engine options, and advanced safety systems. This is no hacked-up badge-engineering job, however. The GMC is definitely more premium thanks to its upscale, avant-garde styling, and classy interior with high-end materials. The Terrain even adopts a push-button gearshift to free up center console space. And yes, GM’s new 1.6-liter turbodiesel four-cylinder is available and the Denali continues as the range-topping trim.
