The Lincoln LS is a mid-size, rear-wheel drive executive sedan that was sold by Lincoln. For its production run from 1999 until 2006, it was based on the Ford DEW98 platform, which was shared with the Jaguar S-Type and Ford Thunderbird. LS versions were originally to be called LS6 and LS8 depending on engine choice, but those designations were replaced with "LS V6" and "LS V8" after Toyota's Lexus division became concerned about the potential for naming confusion with its Lexus LS.
