What is the terminal velocity of a falling car?

Probably 200-250kph in a tumbling scenario, if you managed to point it downwards to make use of it's CoD then who knows... would be a great experiment actually!  Maybe there's already data to extrapolate the CoD to a Tv...?

The tumbling scenario is a pure guess, but I just did some calculations (likely flawed) and the terminal velocity of a Ferrari F430 is 666kph, and a Lamborghini Murcielago is 777kph, a Toyota Poofter Car is 652kph. :tilt:

I might do more later, but I think it would be a cool new stat for manufacturers to add into the spec sheet... :cool:

How about another metric - like "potential"? :p

I made a formula - put it into an Excel thingy and you can just input the vital stats of a car and it gives you the realised potential vs theoretical.  (based on manufacturer specs)

Eg - an F430 achieves about 44% of it's aerodynamic potential on a horizontal plane... :tilt:

Very impressive Ash,  Thers been a formula for Terminal Velocity for sometime.  Which formula have you come up with.

I'm really impressed with the difference between the Ferrari and Lambo.  The old formula, had to have area, density, drag (which you can get from wind tunnel tests I guess) etc etc from memory.

Gees, I'll now have to go down stairs and blow the dust of the old text books and read up. :D

Oh ok I just modified the standard Vt formula and took into account a couple manufacturer specs also - and made a funky spreadsheet where it's simple to add those specs in and get a quick result.
