Tokyo Preview: Toyota 1/X Concept |

As we said before, with the Tokyo Show close, we’re gonna be invaded with Asian concepts. After yesterday we’ve presented the Honda Puyo and the Honda Cr-Z Concept, today we’re gonna have a whole bunch of them. Here’s the first one, the Toyota 1/X Concept. The car, which looks a lot like the current Prius, is a concept vehicle that “maintains an interior space on par with that of the Prius.” Using carbon fiber reinforced plastic, Toyota engineers managed to reduce the weight of the Toyota 1/X concept to about one-third that of the Prius.

The 1/X uses fossil fuel (FFV) technology and a plug-in hybrid powertrain and is powered by a 500cc motor that allows charging from an external power source. Toyota says that the 1/X has a long electric-motor cruising range and while have low CO2 emissions. More photos after the jump.

Tokyo — TOYOTA MOTOR CORPORATION (TMC) announced today that it plans to exhibit eight concept and 13 other vehicles at the 40th Tokyo Motor Show* under the theme: “Harmonious Drive—a New Tomorrow for People and the Planet”.

In keeping with its tradition of highlighting new, automotive possibilities at the Tokyo Motor Show in the form of a wide variety of concept vehicles and groundbreaking technologies, TMC’s exhibit, this time as well, is meant to provide new proposals for the automobile. Planned highlights include a vehicle that completely redefines what it means to be environmentally considerate and one that rewrites the rules of auto design with a proposal for ultra-efficient vehicle packaging.

Through the exhibit, TMC aims to showcase its pursuit of the essential emotional appeal of cars—being fun to drive and a pleasure to use—and to indicate its approach toward making sustainable mobility a reality so that people can coexist in harmony with the environment.


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.
