I have had my car for 3500 miles and this is what I am getting now. 41 mpg highway on hybrid alone a/c 69 mph cruise. 79 mpg highway on electric and hybrid a/c 69 mph cruise 35 miles highway distance 53 mpg city on hybrid alone no a/c 37 mph avg. 66 mpg 1/2 highway using electric and 69 mph cruise and a/c and 1/2 city with hybrid only and no a/c. my commute is 34 miles one way in city driving (main road with lots of lights driving around 55 mph between lights in the early morning with no a/c) 35 miles one way if I take the freeway. The 53 mpg has been a real suprise. however, using the a/c will pull that down into the 40's My best total mpg comes from using the city during the morning on hybrid (no electric) and using the saved electric in the evening and using the highway at 69 with the cruise and a/c.(in the evening the city section is so crowded that the transit time goes from 55 minutes to 1 hr 20 min).
