So today's random observation: All AWD Suzuki SX4s come with an 11 gallon fuel tank. However, all FWD Suzuki SX4s have a 13.2 gallon tank. I assume this is due to the AWD system taking up a bit more undercarriage space.
Thus far, we're averaging 26.1 mpg with our AWD SX4 equipped with a manual trans. The puny 11 gallon tank does require frequent refueling, but they rarely exceed eight gallons.
