The Landau began as a carriage design with a folding fabric top consisting of two sections supported by external elliptical springs. This landau roof design was adopted in early automobiles as a convertible top. The term, however, came to mean a simulated convertible.[1] A landau bar is an ornamental feature located on a car's c-pillar derived from the roof form, primarily used on hearses.[2]
The Nash Rambler Landau introduced in 1950 is a cabrio coach with a power-operated fabric top.[3]
