Tatra 600

The Tatra 600, named the Tatraplan, was a rear-engined large family car (D-segment in Europe) produced from 1948 to 1952 by the Czech manufacturer Tatra. The first prototype was finished in 1946.

History
After World War II, Tatra continued its pre-war business of building passenger cars in addition to commercial vehicles and military vehicles. The factory was nationalised in 1946 two years before the Communist takeover. Although production of pre-war models continued, a new model, the Tatra 600 Tatraplan was designed in 1946-47 by Josef Chalupa, Vladimír Popelář, František Kardaus and Hans Ledwinka. The name of the car celebrated the new Communist planned economy but also referred to aeroplane inspiration ('éroplan' means aeroplane in colloquial Czech).

Originally the 600 was known as the Tatra 107, continuing from Tatra's previous aerodynamic cars- the 77, 87, and 97- as it was intended as a newer, smaller, and cheaper version to replace the outdated Tatra 57. Tatra switched to a new numbering system after WWII, with all car model codes began with 600; as a result, the Tatra 107 became the Tatra 600.

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.

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. It was powered by an air-cooled flat-four cylinder, 1,952 cc rear-mounted engine. 6,342 were made, 2,100 of them in Mladá Boleslav. In 2010, in the UK, the Tatraplan won the 'Classic Car of the Year' competition in the 1940s category.
