As the division entered the 21st century, Lincoln began a period of major transition. In addition to ending production of the long-running Mark series, the Lincoln Navigator SUV had entered production, nearly unchallenged by European and Japanese manufacturers. As buyers of mid-size coupes in the luxury segments had shifted towards sports sedans, Lincoln developed an entry for the segment in the place of the Mark VIII. For 2000, Lincoln introduced the Lincoln LS mid-size sports sedan; coinciding with Premier Automotive Group (see below), the LS was developed alongside the Jaguar S-Type. Though the two vehicles shared a common chassis and related powertrain, no body panels were common between the two vehicles. The shortest Lincoln ever produced at the time, the LS was developed to compete with European and Japanese-produced counterparts, in line with the Cadillac Catera. While the Catera was imported from Germany (as a rebadged Opel Omega), the LS was produced alongside the Town Car and Continental in Wixom Assembly.
