The General Motors web site has this to say about the '85 Wildcat that was developed while Irv Rybicki was in charge of GM styling. Rybicki's production designs tended to be cautious, but this concept car was quite the opposite. Perhaps that was because it was a pure show car and not the type of concept car intended to preview production styling features.
The '85 Wildcat was odd looking -- poorly proportioned, and its front and rear designs looked like they belonged on the opposite ends, as will be shown below. This was largely due to its mid-engine layout. I saw this Wildcat at Expo 86 in Vancouver, and it did not impress me.
The Wildcat's puffy fenders and aerodynamic pretensions strike me as being characteristic of GM styling studio thinking in those days.
