After two prototypes "Ambrož" (December 1946) and "Josef" (March 1947), the 600 went into mass production in 1948.

In 1951, the state planning department decided that the Tatraplan should henceforth be built at the Skoda Auto plant in Mladá Boleslav, leaving Tatra to concentrate on truck assembly.

This was quite unpopular with the workforce at both plants: as a result Skoda built Tatraplans for one year only before the model was discontinued in 1952.

[2] The Tatraplan had a monocoque streamlined ponton-styled 6-seat fastback saloon body with front suicide doors and a drag coefficient (Cd) of just 0.32.

[2][3][4] It was powered by an air-cooled flat-four cylinder, 1,952 cc rear-mounted engine.
