That's a pretty bad Cd, Doggie.
Can I use a 72 HP steam engine that makes max torque at near zero RPM?
Torque blows up pretty fast as the denominator goes to zero at just about
any HP :->
Torque=HPx5252/RPM

Hmmm, that's interesting. OK, here's a questions:
How much torque, at what RPM, with what overall gearing and tire rolling
radius would one need to make a car with a CD of 0.6, and a frontal area of
0.5 m^2 go 150 MPH in air with a density of 1.2 kg/m^3? And since power
doesn't matter, can it be done with less than 72 hp (without a tailwind or
going downhill)?
;)
