Top 10 Most Fuel-Efficient Non-Hybrid Family Sedans

5. 2015 Subaru Legacy: 2.5-Liter, CVT – 26/36/30

If there was an automotive award for quirkiness Subaru would probably win it every year. This small Japanese brand isn’t afraid of going its own way, tenaciously clinging to boxer-type engines and all-wheel drive.

The Legacy is their midsize offering and it makes a strong case for itself in a crowded segment. With a continuously variable transmission and a 2.5-liter horizontally opposed four-cylinder it stickers at 26 miles per gallon in urban motoring and 36 on the highway; combined it clocks in at 30 MPG. Not bad for a vehicle with all-weather traction. Horsepower totals 175 while torque measures 174 lb-ft, a little less than some of its main rivals but it’s still in the ballpark. For more oomph a 3.6-liter boxer six is also available.
