So what can you guys tell me about finess ratios and their importance to achieving a low Cd ?
I have seen a lots of sports cars that look fast and have sloping front ends, but for the most part, all the low drag concept cars that I have seen have rather bulbous front ends.
From Wikipedia :
Fineness ratio - Wikipedia, the free encyclopedia
"Aircraft that spend time at supersonic speeds generally have high fineness ratios, a canonical example being Concorde.
At speeds below critical mach, one of the primary forms of drag is skin friction. As the name implies, this is drag caused by the interaction of the airflow with the aircraft's skin. To minimize this drag, the aircraft should be designed to minimize the exposed skin area, or "wetted surface", which generally implies the fuselage should be somewhat "egg shaped", with a fineness ratio about 4.5. A good example of such a design is the Questair Venture."
Since we aren't breaking the sound barrier with our cars, it would seem that the ideal front end shape would be that of an egg versus a spike.
So
with much respect to those of you that have done it, how does adding a pointed front end to our cars help to lower drag ?
( I'm not 'dissin' you guys that have done it, I'm just not smart enough to grasp the concept. )
Here is my other thread which asks the very same question ( I'm starting a new thread because that one is a mess. This one is dedicated solely to fineness ratios )

And Frank ... I can already see your eyes rolling.
