In 1968 Vignale built three prototypes for Tatra, the Czech luxury marque.
One of them was used in a crash test, the other two survived this ordeal.
Two models were proposed: a four door limousine and a two door coupe. Only
in 1972 production of the T613 sedans started in Czechoslovakia.The T613's
were primarily meant as transport for high government and as taxis, a small
number were exported. The coupe was never put into production. In style with
the Tatra tradition they were equipped with a V8-engine in the rear. In order
to obtain a better weight division, the engine was placed right above the
rear axle, a 'semi mid engine' so to say.
