Toyota unveils an automobile that it coyly calls a "car-shaped music player." The Toyota dB, a compact hatchback, is geared for customers who want to completely immerse themselves in sound. A subwoofer is located in the center console and eight additional speakers surround the interior of the car. The car, introduced in Japan on Tuesday, also includes 11 flashing lights located on the speakers, cupholders and door trim.

Toyota and other carmakers are revving up their car concepts in anticipation of the North American International Auto Show, which takes place in Detroit from Jan. 8 through Jan. 22, 2006.
