| Acceleration comments | Traction control on or off. Who cares? Makes little difference. Engine feels like it's working hard to pull the Terrain through the quarter-mile. Manual mode does nothing to help acceleration. Brake-torquing does little. Just stick it in Drive and wood it. |
| Braking rating | Average |
| Braking comments | Adequate stopping distance over the first three runs, then whoa! Another 15 feet and a soft pedal. Hold on! |
| Handling rating | Average |
| Handling comments | Skid pad: Terrain feels big and heavy here. I could feel the front tires biting for grip around the pad so the AWD is using the front end to pull around the pad. Slalom: There's a real sense of weight here but the Terrain's manners are okay. It's not exciting, but it gets the job done without doing anything scary. |
