Toyota concept vehicles (2000–2009) 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. The Alessandro Volta is a concept car developed in the collaboration of the Japanese manufacturer Toyota and the Italian design company Italdesign Giugiaro. The concept vehicle named after Alessandro Volta, the Italian physicist who invented the battery (and the namesake of the volt
Alessandro Volta Law of Capacitance, and it was for this work the unit of electrical potential has been named the volt. In 1779 he became a professor of experimental physics at the University of Pavia, a chair that he occupied for almost 40 years. Luigi Galvani, an Italian physicist, discovered something he named, "animal electricity" when two different metals were connected in series with a frog's leg and to one another. Volta realised that the frog's leg served as both a conductor of electricity (what we would now call an electrolyte) and as a detector of electricity. He replaced the frog's leg
