The Beetle Convertible with body by Hebmüller goes into production at almost the same time as the new export model VW 1100. As opposed to the convertibles that follow, this is a two-seater with a flat dropping rear and a top that can be completely lowered. Because of a large fire during the summer of 1949, Hebmüller was only able to deliver a few hundred of the 2,000 ordered units. This brief cooperation was followed by a long-term partnership with the Karmann coach works in Osnabrück. In 1949, they began producing a four-seat convertible for Volkswagen and built all open Beetles. These were based on the current export versions, which were superior to the standard models thanks to improved engineering and enhanced interiors.
