The 2014 Hyundai Santa Fe's fuel economy ranges from pretty decent in front-wheel-drive models, to around average for the respective segments in all-wheel-drive vehicles.
The three-row Santa Fe with front-wheel drive earns 18 mpg city, 25 mpg highway, and only highway mileage suffers–by a single mpg–if you opt for all-wheel drive. If you opt for the Santa Fe Sport with the base 2.4-liter four-cylinder, expect to earn 20/27 mpg for front-wheel-drive models, and 19/25 mpg, respectively, with all-wheel drive. There isn't much of a penalty for choosing the turbocharged model in this case, which can also run on regular unleaded gasoline. It's rated at 19/27 mpg for front-drive models, and 18/24 mpg for all-wheel-drive.
