STUDIES IN STREAMLINING FROM THE DAYS OF HORATIO PHILLIPS TO MODERN TIMES. EVOLUTION OF AUTOMOBILE FROM ITS BEGINNING TO PRESENT STREAMLINED SHAPE IS EXEMPLIFIED IN THE 1941 CHEVROLET.

Originally a public domain film from the Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

A streamliner is a vehicle incorporating streamlining in a shape providing reduced air resistance. The term is applied to high-speed railway trainsets of the 1930s to 1950s, and to their successor "bullet trains". Less commonly, the term is applied to fully faired recumbent bicycles. As part of the Streamline Moderne trend, the term was applied to passenger cars, trucks, and other types of light-, medium-, or heavy-duty vehicles, but now vehicle streamlining is so prevalent that it is not an outstanding characteristic. In land speed racing, it is a term applied to the long, slender, custom built, high-speed vehicles with enclosed wheels...

Streamline Moderne is an international style of Art Deco architecture and design that emerged in the 1930s. It was inspired by aerodynamic design. Streamline architecture emphasized curving forms, long horizontal lines, and sometimes nautical elements. In industrial design, it was used in railroad locomotives, telephones, toasters, buses, appliances, and other devices to give the impression of sleekness and modernity.

In France, it was called the Style Paquebot, or "Ocean liner style", and was influenced by the design of the luxurious ocean liner SS Normandie, launched in 1932...

Automobiles

The defining event for streamline moderne design in the United States was the 1933-34 Chicago World's Fair, which introduced the style to the general public. The new automobiles adapted the smooth lines of ocean liners and airships, giving the impression of efficiency, dynamism, and speed. The grills and windshields tilted backwards, cars sat lower and wider, and they featured smooth curves and horizontal speed lines. Examples include the 1934 Chrysler Airflow and the 1934 Studebaker Land Cruiser. The cars also featured new materials, including bakelite plastic, formica, Vitrolight opaque glass, stainless steel, and enamel, which gave the appearance of newness and sleekness. 

Other later examples include the 1950 Nash Ambassador "Airflyte" sedan with its distinctive low fender lines, as well as Hudson's postwar cars, such as the Commodore, that "were distinctive streamliners—ponderous, massive automobiles with a style all their own"...

The drag coefficient is a common measure in automotive design as it pertains to aerodynamics. Drag is a force that acts parallel and in the same direction as the airflow. The drag coefficient of an automobile impacts the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics. Aerodynamic drag increases with the square of speed; therefore it becomes critically important at higher speeds. Reducing the drag coefficient in an automobile improves the performance of the vehicle as it pertains to speed and fuel efficiency. There are many different ways to reduce the drag of a vehicle. A common way to measure the drag of the vehicle is through the drag area...
