Test Drive Reviews

2018 GMC Terrain

The GMC Terrain is all-new for 2018, having received a ground-up redesign to bring it into a new generation. The Terrain has improved in almost every way, despite being smaller and lighter in weight than its predecessor. The main improvements are to driveability, comfort and efficiency, without loss in passenger or cargo room.

The 2018 Terrain sits in a place with few rivals, where shoppers will be required to look differently. Base model versus base model, the Terrain will look expensive compared to some lower-end rivals. But in equipment-to-equipment comparisons, it will often come out ahead in terms of what's included for the price. Its nearest competitor is either a more expensive top-end model from another manufacturer or a more luxurious option from its sister company Buick.

For those reasons, the GMC Terrain should be on more shopping lists than it likely is.

The new 2018 Terrain is offered with three engine choices, four trim levels, front-wheel or all-wheel drive, and seating for up to five.
