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

Fuel Economy beats smaller sized cars, let alone others in the same class. 30mpg is not hard to attain. see full Chevrolet Impala review

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

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
