But it'll be interesting to see those figures if they're available for these "1L" cars.

Hi MetroMPG,

No worries please make changes as you see fit. I make mistakes all the time in my typing and interpretations so I welcome you and anyone else to not hesitate if corrections need to be made here in this thread.

I agree that speed is a very big piece of the puzzle and one we need to analyze in depth for the cars that have thus far achieved 1L performance. I think we also need to determine what is real world speed. I suspect if you ask 100 different people you will get 50 different answers or more depending on region and accepted notions.

My idea of real world speed is between 40-60mph. This covers urban surface street driving as well as highway speed. Obviously you can go much faster on the freeways in some areas but in my state 55mph to 65mph is standard. The majority of in town speed is 45mph or under so I feel as though 40-60mph in my area is a good speed range for real world testing and interpretation.

US speed Limits = http://en.wikipedia.org/wiki/Speed_l..._United_States

I agree that it will be interesting to see just how fast cars such as the Fiat 600 went in order to achieve there 1 liter fuel consumptions. From quick reading I found in several articles that initially the Shell Eco Marathon used a minimum of 30mph baseline speed and then reduced this to 10mph. So I would like to figure out if possible at what speed the Fiat was tested at during its 1973 304mpg run. Hopefully Mr. Smith will have some kind of data on this to share.
