There are a number of five and seven-passenger SUVs on the market, so what's so special about the 2009 Subaru Tribeca? For starters, every Tribeca is equipped with an advanced and capable all-wheel-drive system, a comforting thought for those whose daily commute sometimes includes deep snow and heavy rain. The Tribeca's unique boxer engine design lowers the vehicle's center of gravity and improves vehicle stability, and the Tribeca rates well in the government's front- and side-impact crash tests. Finally, the Tribeca's roomy interior coddles its passengers and stimulates its driver with loads of features, although the same enthusiasm is harder to generate when it comes to the Tribeca's exterior styling.
