The 300 SL production sports car presented in 1954 was based on the successful competition version of 1952. Its space frame weighed only 110 lbs. and was particularly sturdy, but did not permit the fitting of normal doors because of the high frame side members. With its characteristic upward-opening doors, the dream car of the 1950s popularly became known as the Gullwing.
