The vehicle was somewhat limited in speed, as it was unable to drive faster than flowing lava, until Spock and Em/3/Green found a way to rewire the power pack for a high-speed run. It was also not suitable for the terrain, as it was unable to drive up a steep hill. The car ran on a complex power pack. It took the genius of both Em/3/Green and Spock to give the power pack the boost it needed to escape lava flow. It had nine wheels, the front wheel being long and cylindrical. It could hold up to five passengers and also the driver.
