Drag
Posted: Mon May 11, 2015 8:46 am
Read an article recently, about aero drag and motorbikes. Saying how unaerodynamic a motorbike was compared to a car. That a good indicator of the drag is how much power is consumed to propel the vehicle to a certain speed, given that aero drag is by far the most deciding factor at high speed.
I go along the power consumption thing, but I have difficulty with what represents drag.
Reason I say this is because it seems that a modern car will need double the horsepower to achieve the same speed as a bike. Looking around the 130 mph mark.
So if consumed horsepower is the indicator of drag, a bike Seems to have less of it.
Clearly there's more to overall drag than just a slippery shape.
Ok, when it comes to saving the planet, or at least the oil reserves, how efficiently the respective vehicle musters up its necessary horsepower is a different thing again.
