YearBody/PowertrainComment
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

2010 4dr Sedan 170-horsepower 2.5L H4
6-speed manual AWD		 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
