Tatra T77
The Tatra 77 (T77) is one of the first serial-produced, truly aerodynamically-designed automobiles, produced by Czechoslovak 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 rear-mounted 2.97-litre air-cooled V8 engine, in later series increased to a 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 due to its advanced aerodynamic design ...

Tatra 57
The Tatra 57 are a series of two-door compact cars, built by Czechoslovakian company Tatra from 1932. They are popularly known by the nickname ''"Hadimrška"''. Tatra updated the model as the 57A in 1936, and as 57B in 1938. A military adaptation, the 57K, (for ''Kübelwagen'') was introduced in 1941. Through 1945, more than 5,000 Tatra Kübelwagens were built. All versions have a characteristic Tatra backbone chassis, with the drive-shaft running encased in its central structural tube. Tatra ended production of the 57K in 1947, and of the 57B in 1949. With that the company altogether withdrew from making compact cars; from 1948 its smallest model was the 2 litre Tatra 600.

Wind Tunnel
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on Building, buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. ...
