The Volkswagen Kübelwagen was a light military vehicle designed by Ferdinand Porsche and built by Volkswagen during World War II for use by the German military (both Wehrmacht and Waffen-SS). Based heavily on the Volkswagen Beetle. Kübelwagen is a contraction of Kübelsitzwagen, meaning 'bucket-seat car' because all German light military vehicles that had no doors were fitted with bucket seats to prevent passengers from falling out.—Wikipedia
