Consider that this ovoid wonder weighs only 150kg (330 lbs) despite its high-tensile steel plate frame. According to Topia president and CEO, Hideki Sasaki, "If a vehicle of the same size as HUVO is made with existing technologies, it would weigh about 300kg (660 lbs)". They accomplish this feat by using aluminum alloys, carbon fiber reinforced plastic, and ABS resin. The windshield is polycarbonate instead of glass. The actual building techniques are also impressive. The company designed and built its own press molds and utilized equipment ranging from lasers to a rapid prototyping system. The only thing lacking in this concept is the concept of "sexy".
