The look and feel of the 2014 Subaru Tribeca aren't the only dated aspects; this vehicle is also living in the past with its mileage ratings. Most crossovers the Tribeca's size now get at least a mile or two more out of each gallon.
The Tribeca is the brand's heaviest and least fuel-efficient model, and it shows. The EPA rates the Tribeca, which is only offered with a six-cylinder engine and all-wheel drive, at 16 mpg city, 21 mpg highway, for a combined gas-mileage rating of just 18 mpg. 2014 Outback versions with the same six-cylinder engine get 17/25 mpg; and the Outback offers a more efficient base four that achieves 24/30.
