The Teijin Group recently unveiled a super-lightweight electric concept car made with proprietary materials and technologies including carbon fiber composites, polycarbonate resins and bio-derived polyester. Weighing 437 kg, less than half that of conventional electric vehicles, the PU_PA EV (as in “pupa electric vehicle,” a reference to metamorphosis) embodies Teijin’s vision of what a vehicle will look like on the market in five to ten years.
Capable of 60 km/h (37 mph) and a cruising range of 100 km (62 miles), the PU_PA EV offers the functionality and structural integrity of a practical automobile. As a symbolic electric concept car, it features a number of proprietary advanced technologies:

Weight Reduction. The body incorporates a core structure made of carbon fiber composite material. Windows made of polycarbonate resin with a heat absorbing function weigh only half as much as glass. Modularized parts are made with single-piece molding, etc., reducing total parts to about 20.
Biotechnology. Interior items (seats, floor mats, etc.) are made with bio-derived polyester.
Reduced Environmental Burden. Metal-toned TEFLEX PET film is used as an alternative to chrome plating. Low-noise tire cord is made with TEONEX polyethylene naphthalate (PEN) fiber.
Electronics. Multi-device communication using CELL FORM two-dimensional communication sheet.
The vehicle is being exhibited in the Teijin Mirai Studio, a showroom located in the same building as Teijin’s headquarters in Tokyo that presents the group’s materials and technologies.
Teijin will use its innovative concept car as a marketing tool to showcase the group’s environmentally responsive technologies and customer-oriented solutions.
The Teijin Group is cultivating markets and developing technologies in four strategic sectors: automobiles and aircraft, information and electronics, healthcare, and environment and energy. The Teijin Technology Innovation Center and the Teijin Composites Innovation Center were established in 2008 to pursue joint-development initiatives with customers. Along with the Plastics Technical Center, the facilities have enabled the Teijin Group to enhance its “customer lab” program of solution-oriented collaboration with customers.
The Mobility Business Project, a department overseen directly by the CEO, was established in April 2009 to support business expansion in the automobiles and aircraft sectors, focusing on the development of materials and technologies for lightweight, hybrid and electric vehicle designs.
Based in Tokyo and Osaka, Japan, Teijin is a global technology-driven group operating in five main fields: synthetic fibers (aramid fibers, carbon fibers and polyester fibers); films and plastics; pharmaceuticals and home health care; trading and retail; and IT and new products. The group had consolidated sales of US$10.5 billion (JPY 943.4 billion, USD 1=JPY 90) in fiscal 2008 and employs 19,453 people worldwide, with 169 companies around the world.
