There are not many photos of this car,but if you'll do a search for the 1979 C-111 IV you'll notice that Dr.Liebold blunted the nose ('flachbau-schnoz' I think Porsche calls it) and then extended the boat tail out nearly all the way.
After festooning the car with induced-drag splitters and wings the car's drag remained at Cd 0.195.
At Fiat's Nardo,Italy test track,and with more power,the C-111 IV pushed over 250 mph.This is the record that GM's OLD's long-tail AEROTECH would beat in 1987,out at Ft. Stockton,Texas.
And we notice,that for the long courses,and highest speed,Ed Welborn also chooses the full boat tail.(A.J.Foyt saw 281-mph on one lap and this was not the top speed of that car).
