Toyota presented its concept car "Fine-N" as a prototype of a fuel-cell hybrid car at the 37th Tokyo Motor Show 2003.

Toyota has increased the electricity generated per unit mass of hydrogen by improving on ancillary equipment to supply fuel and air. Another key is to increase the pressure in a hydrogen tank from a conventional pressure of 350 to 700 bar. Into the same volume of a hydrogen tank, about 1.5 times more hydrogen can be filled under 700 bar than under 350 bar. As a result, the number of tanks (four with conventional technology) has been reduced to three, with the total amount of stored hydrogen rising as well.

Another major feature of Fine-N is a security system based on face recognition technology for starting the engine.
