The Tatra V570 was a prototype 1931-33 car developed by a team led by Hans Ledwinka, Erich Ledwinka and Erich Übelacker. The aim of the construction team was to develop a cheap people's car with an aerodynamic body. The first T57-V570 prototype with rear air-cooled two-cylinder engine placed in the former rear luggage compartment of conventional T57 two-seater dropped head coupe was completed late in 1931. 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, now streamlined V570 four-seater was built in 1933, two years before the first Volkswagen, which bears a strong resemblance to the Tatra – it was misappropriated in the opinion of Tatra, by Adolf Hitler and Dr. Ferdinand Porsche in circumstances about which the German company remains intensely sensitive.

The Tatra 77 (T77) is one of the first serial-produced, truly aerodynamically-designed automobiles, produced by Czechoslovakian company Tatra from 1934 to 1938. It was developed by Hans Ledwinka and Paul Jaray, the Zeppelin aerodynamic engineer. Launched in 1934, the Tatra 77 is a coach-built automobile, constructed on a platform chassis with a pressed box-section steel backbone rather than Tatra's trademark tubular chassis, and is powered by a 60 horsepower (45 kW) rear-mounted 2.97-litre air-cooled V8 engine, in later series increased to a 75 horsepower (56 kW) 3.4-litre engine. It possessed advanced engineering features, such as overhead valves, hemispherical combustion chambers, a dry sump, fully independent suspension, rear swing axles and extensive use of lightweight magnesium alloy for the engine, transmission, suspension and body. The average drag coefficient of a 1:5 model of Tatra 77 was recorded as 0.2455. The later model T77a, introduced in 1935, has a top speed of over 150 km/h (93 mph) due to its advanced aerodynamic design which delivers an exceptionally low drag coefficient of 0.212, although some sources claim that this is the coefficient of a 1:5 scale model, not of the car itself. Recent article confirmed the Tatra 77/77a drag coefficient for real full-size car as 0.36.
