Step 1 : Introduction to the question "What automaker started out as a motorcycle-sidecar business known as the Swallow Sidecar Company?"
Jaguar’s business was founded as the Swallow Sidecar Company in 1922, originally making motorcycle sidecars before developing automobiles. Under the ownership of S. S. Cars Limited, the business extended to complete cars made in association with Standard Motor Co. many bearing Jaguar as a model name. Its first use of the name Jaguar was on a 1936 model called the S.S. Jaguar - the S.S. was for Swallow Sidecar. After the Second World War, due to the unfavorable connotations of the SS initials, the company was renamed Jaguar Cars Ltd in 1945.
