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

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

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

2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD
To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review

You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. see full Infiniti G review

With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
6-speed manual RWD
While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review
