Pep Boys, the national auto part chain based in Philadelphia, maintains the use of the name by the Dearborn automaker would infringe on its trademarked brand name for tires, the Detroit News reports.
Ford announced in April it would build the Futura beginning in 2005 and that the name comes from its Ford Falcon Futura built between 1959 and 1962.
Ford has asked U.S. District Judge Nancy Edmunds to rule against Pep Boys. A Ford spokeswoman says the company has no plans to abandon the Futura name and is confident of success.
The mid-size Futura sedan is a key element of Ford's product plan and will fill a gap between the Ford Focus and the larger Ford Five Hundred.
