The Terrain is a uniquely styled 5-passenger crossover SUV which is closely related to the Chevrolet Equinox. Although it appears larger on the outside, the Equinox has roughly the same or less interior volume than the popular Honda CR-V. With a passenger volume of around 100 cubic feet, the Terrain is roughly equivalent to a mid-sized sedan like the Chevrolet Malibu. Buyers can choose between a 182-bhp 2.4l four-cylinder and a 301-bhp 3.6l V6 engine. Every model offers a choice of FWD or AWD. The V6 engine offers significantly more power at the expense of fuel economy. GMC offers the Terrain in a variety of trim levels starting from about $26,000. The base model includes common power equipment and alloy wheels. The range-topping Denali model priced from $35,000 includes heated leather seats and a power rear tailgate.

A Denali model joins the Terrain lineup. A new 3.6l V6 engine replaces the prior model years 3.0l V6.
