Although a little late to the party, Subaru has entered the SUV market with the introduction of the new 2006 B9 Tribeca. Available with five- or seven-passenger capability, the well-equipped B9 Tribeca seems to have found a place in a crowded segment. The 2006 Subaru B9 Tribeca comes standard with full-time all-wheel-drive and is powered by a 250-horsepower flat six linked to a five-speed automatic transmission.
