I believed all Subaru Legacy and Impreza since 1992 listed higher Fuel Consumption (or lower mileage) Rated by EPA and other Agencies than a Honda Accord or Toyoda Camry.

But the Fact that Subaru mostly AWD, and Honda/Toyoda and Nissan are FWD; they might be more fuel Economy in the Summer; but when it comes to Wet/Slippery Roads and Snows, then the Subaru will out-shine the others.

We own many Subaru, Legacy/ Outback and we always found Subaru TCO and pleasure Driving in All Weather Conditions.
