The door trim carries on the minimal, simple theme with the armrest, speaker grille and courtesy lamp all enclosed in a single, lightweight enclosure. The see-through Lexalite enclosure has a triangular theme that is repeated throughout the interior and includes the knobs and the seat itself. The enclosure is stepped off the door panel, echoing the sensation of being filled with air. The interior features unique materials including Lexalite acrylic panels on the doors, centre console and instrument cluster. The entire interior is tied together with smooth leather and metal accents. Following its world debut at the 2001 Chicago Auto Show, the HCD6 will be displayed at key auto shows around the world.
