Ryan,
I don't know if you can find this in the internet. But in 1975? a
paper was presented at the SAE conference titled
"Is 150 mpg possible." There were a lot of papers on this subject
published back then? Hmm? Why aren't we conducting the same research
today.?
This paper contained a great graph showing the HP to overcome friction
due to drive train and wheel versus HP required to over come air
resistance by vehicle speed. Very interesting stuff.
In answer to you question. Around 50 mph you need 13 HP to drive the
vehicle if it is air dynamic (around o.3 drag coefficient) and have
tires around 35 psi.
Bob
