2007 Toyota 1/X Concept

The 1/X (pronounced 'one-Xth') is a concept vehicle that redefines from its very roots the idea of what it means to be environmentally considerate. Among its attributes, the vehicle-with a design that aims to harmoniously coexist with people and society-weighs only '1/Xth' that of other vehicles in its class.

• Maintains an interior space on par with that of the Prius, with an aimed-for fuel efficiency that is double and a weight reduced to 420 kilograms (about one third the weight of the Prius).

• Combines fossil fuel consumption-reducing FFV* technology and a plug-in hybrid powertrain with a displacement of only 500cc that allows charging from an external power source and a longer electric-motor cruising distance; thus, in addition to being adapted for energy diversity, emits less CO2 and contributes to the prevention of air pollution.

• Locates the power unit beneath the rear seat (for a midship, rear-wheel-drive system) to contribute to an innovative and highly efficient package.

• Adopts light but highly rigid carbon fiber reinforced plastic (CFRP) throughout the body frame to ensure superior collision safety, while allowing narrower pillars for a better field of vision.
