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

Subaru Legacy Real Gas Mileage: Pros
YearBody/PowertrainComment
2013 4dr Sedan 256-horsepower 3.6L H6
5-speed shiftable automatic AWD
The downside of the H6 is not great gas mileage, but for what you are getting, it is not bad. On the highway with cruise control have managed to get about 30 mpg. In a mix of city and highway it gets 23 mpg. In city only it gets 18 mpg. Again, for AWD not bad, but not great. Want better gas mileage, get the H4 engine. see full Subaru Legacy review
2010 4dr Sedan 170-horsepower 2.5L H4
6-speed shiftable CVT AWD
With the CVT transmission, rpms stay low and there is no shifting saving on fuel. see full Subaru Legacy review

I average 43mpg in a little over half highway driving. I get 55mpg on the highway and about 35mpg in city driving. This is very impressive considering this car's performance. see full Subaru Legacy review

Subaru Legacy Real Gas Mileage: Cons
YearBody/PowertrainComment
2010 4dr Sedan 170-horsepower 2.5L H4
6-speed manual AWD
A bit thirstier than I had hoped - but the AWD probably has a lot to do with that. see full Subaru Legacy review
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 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
