The Terrain benefits from two efficient engines, each making use of variable valve timing and direct injection. A standard 2.4L 4-cylinder engine makes an impressive 182 horsepower yet delivers 32 mpg on the highway. A 3.6L V6 is optional on all trims. It makes 301 horsepower and returns a combined EPA-estimated 20 mpg. A 6-speed automatic transmission is the only transmission available. Front-wheel drive is the standard drivetrain, but all-wheel drive is available.
Storage areas are everywhere in the cabin, including an oversized glovebox, an enclosed storage bin in the instrument panel above the center stack and a closed storage bin under the center armrest large enough for a laptop computer. The rear seats feature MultiFlex, which allows the seats to move back and forth a total of eight inches for the best rear legroom in the segment.
