Abstract
This disclosure relates generally to motor vehicles, and more particularly to motor vehicle and device for visually indicating a speed of the motor vehicle, and method thereof. In one embodiment, a method is provided for visually indicating a speed of a motor vehicle. The method includes receiving an instantaneous speed of the motor vehicle from one or more odometry devices of the motor vehicle and an instantaneous temperature on an external surface of the motor vehicle from one or more temperature sensors. The method further includes configuring one or more thermoelectric couple strips to regulate temperatures of one or more corresponding thermochromic paint coating layers disposed on the external surface of the motor vehicle, based on the instantaneous speed and the instantaneous temperature, to dynamically control indication of a color pattern associated with a range of instantaneous speed of the motor vehicle.
