Continuing Charles Nash's decades of success by building cars "embodying honest worth ... a price level which held out possibilities of a very wide market." Mason began exploring the possibilities of aerodynamics for automobile designs and used of wind tunnel tests during World War II. Nash’s Chief of engineering, Nils Erik Wahlberg, worked with Theodore (Ted) Ulrich in the development of Nash's all-new and radically styled 1949 Airflyte models. This was a comprehensive adoption of aerodynamic principles in a low-priced mass-produced post-war automobile. The Airflyte's design also extended its body over car's front wheels, and these enshrouded front wheels remained a Nash hallmark until 1957.
