My 2012 Honda Fit is rated 27 city/33 highway. My overall average is 36 mpg. Avoiding braking by cutting the cruise when you see a red light ahead, driving in the right lane at the speed limit, and leaving a good gap between you and the vehicle in front, are my "hypermiling" habits. Also tempered by, as others have said, not being a big nuisance to other traffic. I have 68,000 miles on the vehicle (commute is too long, and we had a cabin for 2 years of this). At 65,000 miles, I felt for sure it would need brakes, so I took it into repair shop and they said brakes look fine, only about 1/2 wear. So at that rate, I'll get 130,000 miles on my brakes!
