Agree w/ Wayne. I had an approx. 5 mile round trip commute on suburban streets with few stops and was consistently able to beat 70mpg in my 5spd. The stops are critical. My current commute has many more stops and speedbumps in it, and I find it hard to get over 60mpg.xcel said:you might be able to squeeze some fantastic numbers out of a 5-speed Insight even in an all city environment.
