A recent makeover gave the GMC Terrain (and its cousin the Chevrolet Equinox) a more refined silhouette to align it with the manufacturer's other models. The interior presentation has also been updated and is more upscale in the Terrain Denali. There’s a choice of a turbocharged, 1.5-litre four-cylinder engine (170 horsepower) or a 2.0-litre turbo (252 horsepower). A turbo-diesel engine (6.1 L/100 km on the highway) is also available, giving it an edge on the competition.
