That is highway at 65mph. Top speed is 93mph. 6,000 miles since July. I get 87mpg all summer long. Low 90's at 50mph with normal cruising. It will be better next year with longer gears.

Now I gotta get me one of them magic Insights to go with my new magic tires. I've had my 2001 Insight since 05. Put 130,000 miles on it. New batteries ect. in 07. I hypermile and I draft. No kill switch, P and G, or MIMA though. Best tank under perfect conditions 69.5mpg. Tank fill not computer readout. The computers read high. Average lifetime summer mpg was 67 before they changed the gas and the engine started to get recently tired.
