The Chrysler Millennium was a concept car, a four-door, four-seat sedan with a pillarless body, conventional front doors and rear sliding doors. Its proportions were derived from the Lamborghini/Chrysler Portofino, shown 16 months earlier at the Frankfurt IAA, though unlike that car's four scissor doors, the Millennium relied on its sliding rear doors to give access to the luxurious interior. While the Portofino used a Lamborghini mid-engine layout, the Millennium switched to a front-engine configuration; Chrysler did not disclose further details of its drivetrain. The car measured 495 cm in length, 191 cm in width and 135 cm in height, with a wheelbase of 310 cm.
Chrysler presented the Millennium as a preview of what car buyers might expect by the mid-1990s, promoting it as a safety-focused design incorporating the company's technology. Its features were grouped into four safety categories: monitoring systems such as ABS, traction control, a memory-equipped magnetic access card, voice-activated engine controls with self-diagnosis, an anti-dive seat system, and an electronic selective schedule transaxle; protective systems including airbags, a voice-activated satellite navigation system, a voice-activated telephone, an anti-theft system and a child safety seat; vision-related systems such as forward and rear-facing infrared radar, a head-up display, heated windscreen and rain-sensing wipers; and warning systems covering blind-spot monitoring, brake pad and fluid level sensors, tire pressure monitoring, automatic hazard flashers and a "Drunk Driver Disabler" intended to prevent impaired driving.
Notable styling details included a light band across the front and side protection trim rising toward the rear. The Millennium was shown at the Tokyo Motor Show in autumn 1989 but was not displayed in Europe.
