Toyota 1/X Concept Makes North American Debut At 2008 Chicago Auto Show

07 February 2008

Chicago: The Toyota 1/X concept vehicle made its North American debut today at the 2008 Chicago Auto Show.

Developed by Toyota Motor Corporation, the Toyota 1/X compact hybrid offers a glimpse into the next era of automotive technological design. It redefines from its very roots the idea of what it means to be environmentally considerate.

Pronounced 1/Xth, the name is derived from its vehicle mass, fuel consumption and emissions output, each totalling a fraction of that of other vehicles in its class.

The 1/X features an aerodynamic ultra-lightweight design that maintains the interior space of the Toyota Prius hybrid and is approximately one-third the weight of the Prius. Its low 926-pound curb weight is partially achieved through the use of a light but very strong carbon fiber reinforced plastic (CFRP) throughout the body frame.

The aerodynamic shape of the 1/X and unique cabin design result in smaller pillars, allowing passengers more visibility and helping to create a greater sense of openness and freedom with its outer surroundings for driver and passengers. The CFRP material is lighter and stronger than traditional metals, creating a shock-absorbing like structure with cross-sections that help absorb energy during an impact.

The 1/X roof is produced from a bio-plastic made from environmentally-responsible material derived from kenaf and ramie plants. The result is a roof that improves heat insulation, emits less carbon dioxide, increases the amount of light entering the cabin, and reducing noise.
