What Our Members Are Saying about the Real 2009 Subaru Legacy MPG

2009 Subaru Legacy Fuel Economy: Cons
YearBody/PowertrainComment
2009 4dr Sedan 170-horsepower 2.5L H4
4-speed shiftable automatic AWD		 The fuel economy with a 4 cylinder 170 hp engine is pretty disappointing at 22-23 mpg. The AWD system is responsible for some of the loss but I also drive an AWD Acura TL SH-AWD with a 6 cylinder 305 hp engine that is only marginally worse at 18-19 mpg.
