With so many SUVs on the market, the Tribeca tends to get lost in the crowd. First launched in 2006, this vehicle has seen a drop in its sales numbers over the last two years. Just one engine is offered, a 3.5L flat-6 that churns 256 hp and 247 lbs.-ft. of torque. The 5-speed automatic gearbox is also your sole transmission option, and all this is combined with Subaru’s legendary AWD.
