The Terrain benefits from two engines that are more efficient than ever, each making use of variable valve timing and direct injection. A standard 2.4L 4-cylinder, E85-capable engine makes an impressive 182 horsepower yet delivers 29 mpg on the highway. All but the base trim offers an optional 3.6L V6 engine. This engine produces 301 horsepower and 23 mpg on the highway. A 6-speed automatic transmission is standard with both engines. Front wheel-drive is the standard drivetrain, but all-wheel drive is available.
Storage areas are everywhere in the cabin, including an oversized glovebox, a closed 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.
Standard equipment on base SLE trims includes Bluetooth, a rearview camera, 17-inch painted aluminum wheels, StabiliTrak stability control, traction control, 4-wheel anti-lock brakes, six air bags, an anti-theft system, an XM Satellite Radio-ready audio system, iPod and MP3 capability and six months of OnStar service. Power windows, door locks, remote keyless entry, a tilt and telescoping steering wheel, as well as power mirrors and automatic headlamps round out the generous standards list.
Optional equipment on the SLE trim includes satellite radio, remote start, heated front seats, navigation, a sunroof and 19-inch wheels.
