The Tatra 87 has unique bodywork. Its streamlined shape was designed by Hans Ledwinka and Erich Übelacker and was based on the Tatra 77, the first car designed with aerodynamics in mind. The body design was based on proposals submitted by Paul Jaray of Hungarian descent, who designed the famous German Graf Zeppelin dirigibles. A fin in the sloping rear of the Tatra helps to divide the air pressure on both sides of the car, a technique used later in aircraft. Tatra 87 had a drag coefficient of 0.36 as tested in the VW tunnel in 1979 as well as reading of 0.244 for a 1:5 model tested in 1941.
