Chronology
Successor Tatra T97

The Tatra V570 was a prototype early 1930s car developed by a team led by Hans Ledwinka and Paul Jaray. The aim of the construction team was to develop a cheap people's car with an aerodynamic body. However the company's management decided that the revolutionary ideas introduced in the prototype should be introduced in large luxurious cars, and therefore the team abandoned the project of small cars in favour of the Tatra T77, the world's first serially produced aerodynamic car. The project of a small car was later continued and led to introduction of the Tatra T97. The second V570 was built in 1933, two years before the first Volkswagen, which bears a strong resemblance to the Tatra - it was misappropriated by Hitler and Dr. Porsche in circumstances about which the German company remains intensely sensitive.

In the early 1930s Tatra engineers, under the direction of Hans Ledwinka's son Erich and design engineer Erich Übelacker, started work on the development of a small people's car with a rear-mounted engine in a backbone frame. Ledwinka believed that a rear-mounted engine RR layout would bring with it several big advantages – i.e. reducing the efficiency loss, noise and vibration of the driveshaft of the FR layout. No driveshaft meant there would be a flat floor with no need for central floor tunnel so that the passengers' seating position would be lower and well forward of the rear axle, which would lead to a lower centre of gravity, more favourable inter-axle weight distribution, and lower overall height. Mounting the engine in the rear would mean shortening the front part of the body to make a longer tail possible, which was consistent with the laws of aerodynamics. Also, engine noise would not disturb the passengers and would not be heard when driving at a speed of over 50 km/h. Air-cooling would be simpler and more effective at coping with the extremes of temperatures during the depths of winter and height of summer, than water cooling systems of the time, considering the climate in Central-Europe. As the company was considering starting to manufacturing aeroplanes, it got experience with laws of aerodynamics and decided to apply them for the prospective car.

The initial proposal of the concept was presented by Tatra designer Erich Übelacker, who previously worked on the Tatra 57 car. However, at the time Übelacker's proposal was strongly criticised by Ledwinka. When he was facing the prospect of leaving the company, he finally presented the project with aerodynamic car body with a teardrop rear, which would be used to accommodate the whole drive-line of the car. Paul Jaray, the noted Zeppelin designer, produced a prototype aerodynamic body for the Tatra 57. Übelacker was a mercurial young engineer with great imagination and a lot of enthusiasm - however he lacked the perseverance needed to bring his ideas to fruition, and that is when Ledwinka stepped in to finish the work which might otherwise have come to nothing. The new design was initially tried under a body which was not aerodynamic (the first V570 prototype). Two pieces of the first V570 were made in 1931.
