To monitor the FCX Concept's fuel and performance, the driver is faced with a concave instrument panel displaying a kaleidoscope of multicolored virtual gauges. Among these, a circular display expands, contracts, and changes color according to the level of hydrogen being used at any one time. A green semicircular power meter on the left of the instrument cluster illuminates in blue to indicate the amount of power drawn from the fuel cell, and in green when the car is running on battery power. On the right-hand side, a fuel gauge displays the level of hydrogen in the tank.
