A phaeton is a style of open automobile without any fixed weather protection, which was popular from the 1900s until the 1930s. It is an automotive equivalent of the horse-drawn fast, lightweight phaeton carriage. A popular style in the US from the mid–1920s and continuing into the first half of the 1930s was the dual cowl phaeton, with a cowl separating the rear passengers from the driver and front passenger. Phaetons fell from favour when closed cars and convertible body styles became widely available during the 1930s. Eventually, the term "phaeton" became so widely and loosely applied that almost any vehicle with two axles and a row or rows of seats across the body could be called a phaeton. Convertibles and pillarless hardtops were sometimes marketed as "phaetons" after actual phaetons were phased out. History The term phaeton had historically described a light, open four-wheeled carriage. When automobiles arrived it was applied to a light two-seater with minimal coachwork. The term was interchangeable with spyder, derived from a light form of phaeton carriage known as a spider. Originally meant to denote a faster and lighter vehicle than a touring car, the two terms eventually became interchangeable. A detachable folding or rigid roof could be added before a drive in preparation for inclement weather, and side curtains or screens could be installed once the roof was in place. This was mainly temporary and partial relief rather than the more permanent, watertight protection offered by a convertible. As a result, a phaeton was much lighter than the sturdier, weather-ready convertible. Since the body was entirely open, it was easy to add or remove an extra row of seating where space had been left in the original construction. A phaeton differs from a convertible in having no winding or sliding windows in the doors or the body. Doubles and triples There were also double phaetons, with two rows of seats, triple phaetons, and closed phaetons. After 1912, American use of the term began to be most closely associated with the "triple phaeton" body configurations that had room for three rows of seats, whether all three were installed or not. This also led to the term "phaeton" becoming similar to, and eventually interchangeable with, the term "touring car". Specific use of the term phaeton is with the dual cowl phaeton, a body style in which the rear passengers were separated from the driver and
