FSM Beskid
Beskid was a series of economy hatchback car prototypes in Poland designed by BOSMAL Automotive Research and Development Center during 1982-1987 that never went into mass production due to political reasons. All seven prototypes were to be destroyed, but three managed to be saved. The body style was patented, but BOSMAL lacked funds for the extension of the patent, and it was re-used by French Renault Twingo, released more than 10 years later, when the Polish patent expired.
