What Our Members Are Saying about the Real Gas Mileage of the 2008 Subaru Legacy

2008 Subaru Legacy Real Gas Mileage: 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. see full Subaru Legacy review
2008 4dr Sedan turbocharged 243hp 2.5L H4
5-speed shiftable automatic AWD		 heavier concumption due to awd and power see full Subaru Legacy review
2008 4dr Sedan 245-horsepower 3.0L H6
5-speed shiftable automatic AWD		 I do not dislike the fuel econ, its AWD and I knew that going into the purchase, after you walk away from a totaled vehicle, safety becomes the prioroty over fuel econ. Have been able to get 32mpg out of both vehicles with smart driving see full Subaru Legacy review
2007 4dr Sedan turbocharged 243hp 2.5L H4
5-speed manual AWD		 Room for improvement without driving below the speed limit. see full Subaru Legacy review
