Cd 0.137 and stability

Ford Motor Company claimed high speed stability for their 1985 PROBE-V,Cd 0.137,concept car.They incorporated a vestigial fin at the bottom of the rear slope to tune the center-of-pressure.GM/AeroVironment incorporated tail fins under the tail of the 1987 Sunraycer for the same reason.It's pretty obvious that,if you have a high speed aerodynamic stability issue,it can be resolved aerodynamically as well.Spirit of Ecomodder is rock solid under all driving conditions encountered so far.
