Car and Driver (sometimes abbreviated C/D) is an American automotive enthusiast magazine. Its total circulation is 1.31 million. It is owned by Hearst Magazines, who purchased prior owner Hachette Filipacchi Media U.S. in 2011. Originally headquartered in New York City, the magazine has been based in Ann Arbor, Michigan since the late 1970s. Car and Driver was founded as Sports Cars Illustrated in 1955. In its early years, the magazine focused primarily on small, imported sports cars. In 1961, editor Karl Ludvigsen renamed the magazine Car and Driver to show a more general automotive focus. 2005 marked the 50th anniversary of Car and Driver . Car and Driver once featured Bruce McCall, Jean Shepherd, Dick Smothers, and Brock Yates as columnists, and PJ O'Rourke as a frequent contributor. Former editors include William Jeanes and David E. Davis, the latter of whom led some employees to defect in order to create Automobile Magazine.
