| 2008 | 4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD |
Large trunk space seems to sacrifise rear seat area. see full Chevrolet Impala review |
| 2008 | 4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD |
Not enough leg room. see full Chevrolet Impala review |

When the drivers seat is all the way back there is little rear seat legroom for tall folks. see full Chevrolet Impala review |

| 2011 GMC Acadia Seat Room and Comfort: Pros | ||
| Year | Body/Powertrain | Comment |
| 2012 | 4dr SUV 288-horsepower 3.6L V6 6-speed shiftable automatic AWD |
The third room has enough head room to even fit an adult comfortably and is wide enough to accommodate three individuals. It is one of the few SUV's that offer 8 seat capacity and has a larger interior capacity than a Tahoe. see full GMC Acadia review |
| 2011 | 4dr SUV 288-horsepower 3.6L V6 6-speed shiftable automatic AWD |
we travel with adults not children and find the 2nd row very comfortable. see full GMC Acadia review |
| 2010 | 4dr SUV 288-horsepower 3.6L V6 6-speed shiftable automatic AWD |
Better 2nd & 3rd row comfort than the Honda Minivan (this is to be a daily driver for a family with 4 kids under 10) see full GMC Acadia review |
