The Fine-N was a concept vehicle that was an update to the Fine-S and was shown at the October 2003 Tokyo Motor Show and the January 2004 North American International Auto Show.
The Fine-N uses a hydrogen fuel cell electric hybrid system which drives four independent 25 kW electric motors - one in each wheel. The hybrid system uses a Lithium-ion battery under the seats. Control is by drive-by-wire.
