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

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		 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
