Hyundai, like practically every other automaker in Frankfurt, is showing off its green-wares. The i-Blue is the poster-child for the automaker's environmentally focused future, with a 100 kW motor powered by a fuel cell. Developed by Hyundai's Design and Technical Center in Chiba, Japan, the i-Blue's platform shares the concept's name, and will likely underpin future D-segment crossovers with a 2+2 seating arrangement.
