A vintage 1930 advertisement promoting the sleek, aerodynamically engineered cars of the future.
The earliest automobiles were little more than horse-drawn carriages fitted with engines. Their tall passenger compartments, exposed wheels, upright windshields, running boards, and boxy front ends generated significant aerodynamic drag. At the relatively low speeds of the early 1900s, this was not a major issue. However, as engines became more powerful and road networks improved, air resistance increasingly limited both speed and efficiency.
During the 1920s and 1930s, engineers began applying lessons from aviation and conducting wind-tunnel testing to better understand how air moved around vehicles. Their research revealed that sharp edges, exposed parts, and abrupt rear sections created turbulence that greatly increased drag. As a result, designers started rounding bodywork, integrating fenders into the overall shape, sloping windshields, enclosing rear wheels, and tapering the rear of the vehicle to allow air to flow more smoothly.
Some of the streamliners developed during this period were remarkably advanced. One of the best examples was the Tatra 77, introduced in 1934. Depending on the measurement method used, its drag coefficient has been estimated at roughly 0.21 to 0.36—an impressive achievement that remained competitive with many vehicles built decades later.
