Howard;
As far as mid-engine "sports" cars are concerned, I'm afraid Landa is pretty
far off in his CP location. Those cars typically have 60% of the weight on
the rear wheels, so their CG is pretty far aft-- requiring a CP that is even
further aft.
Perhaps his "modern aerodynamic shaped track cars" definition covers this. I
suppose it depends on his definition of what the car is.
In any case, the car chassis, suspension, etc should handle well at moderate
speeds-- get it stable before going to high speeds where aerodynamics are
another concern. That is, if it handles like a pig at low speeds, making it
work at high speed by playing with aerodynamics is a nightmare. Old
swing-axle VWs were awful on the autobahn on a windy day!
It is far more rewarding and safer to get the car set up for good handling
and then work on high speed aerodynamic stability.
