Chevrolet Impala Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2012	4dr Sedan 300-horsepower 3.6L V6 6-speed automatic FWD	I got 468 miles on a tank of gas from Greenville TN to Charleston SC then to Myrtle Beach. Very impressed see full Chevrolet Impala review
2011	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	So far so good with E10 Fuel I am getting an average of 27 and I only have 500 miles on it so far. I now have over 3000 miles and just got back from a long trip 1/2 of it hilly. I set the cruise on 67 and let it go averaged over 32mpg by the end of trip see full Chevrolet Impala review
2009	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Averaging 25.0 mpg in mixed driving, very good for the size of the vehicle and the the fact that it is a V6. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	Its a full size car that gives good performance and still gets 30 MPG on the highway. see full Chevrolet Impala review
2008	4dr Sedan 211-horsepower 3.5L V6 4-speed automatic FWD	If driven carefully, 22-30 MPG around town and 33-36 MPG highway. If you are a sloppy driver, make that 18-20 and 25 MPG. see full Chevrolet Impala review
2008	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	Mileage averages 23-24 around town and close to 30 on road trips which is quite good considering engine size and power. see full Chevrolet Impala review

2007	4dr Sedan 233-horsepower 3.9L V6 4-speed automatic FWD	Only get about 25 mpg on interstate with the 3.9 Active fuel management is a gimmick in my opinion and older GM cars with a V6 I have driven have been better with fuel economy than the 3.9. see full Chevrolet Impala review

Subaru Legacy Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
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

Subaru Legacy Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
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

2005	4dr Wagon turbocharged 250hp 2.5L H4 5-speed manual AWD	poor gas mileage for its size. getting about 18 mpg average in mixed driving. the car also requires 91+ octane. see full Subaru Legacy review
