The I.D.E.A KAZ was a luxury limousine concept. The KAZ, Keio Advanced Zero-emission vehicle, has a total of 8 wheels, 6 of which are involved in turning. Each of the KAZ\'s 8 wheels is powered by its own electric motor - hence the zero emissions.Unfortunately, whereas most luxury vehicles have names which evoke a sense of prestige and quality, the I.D.E.A KAZ sounds more like an electronic gadget.
