Dear Guy,
If you were travelling through a perfect void in outer space, you
could turn off the engine and coast. You would not slow down.
However, we live on the earth, where we have to deal with friction.
In automotive applications, friction shows up as air resistance,
rolling
I have developed an acceleration modeling program which demonstrates
many of these concepts. Let me know if anyone would like to play with
it and I will send it along. I can also send a full set of the
applicable equations.
Respectfully,
Forbes
I would. Thank you!
I would like a copy please.

resistance of the tires, which remains constant relative to velocity
(but not vehicle mass), and inefficiencies in the drivetrain and

A friend of mine tried something like this several years ago on a
human powered vehicle he was racing. He used fans to pull the air
going by closer to skin of his vehicle, causing air flow which
aproximated a laminar flow more closely. I am not sure how successful
he was, but everything
There is no energy consumed simply because an object is travelling at
a certain velocity; an object in motion tends to stay in motion.
If this were true, we'd just turn off the engine and coast...

Air resistance goes up dramatically as a function of speed, per the
following equation:
Power = 0.5*Cd*FA*V^3
where
Power is the power consumed by the vehicle
Cd is the drag coefficient of the vehicle
FA is the frontal area
