Toyota 1/X Concept Makes North American Debut

The Toyota 1/X concept vehicle made its North American debut at the 2008 Chicago Auto Show, with a carbon fibre reinforced plastic (CFRP) throughout the body frame.

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 fibre reinforced plastic (CFRP) throughout the body frame.

Developed by Toyota Motor Corporation, the Toyota 1/X compact hybrid offers a glimpse into the next era of automotive technological design. The Toyota 1/X 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 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.

On the inside, the 1/X employs four ultra-lightweight seats made of polyester fibre that is knitted three-dimensionally for added comfort. The material functions like a spring or damper that helps create a cushion-like feel for all occupants.

The ultra-lightweight stature of the 1/X also helps contribute to a fuel efficiency target that would double that of the Prius and allow the 1/X to operate with an ultra-small hybrid powertrain located under the rear seat. The system combines a home rechargeable plug-in hybrid unit with a small 500cc 0.5-liter flexible-fuel engine that is 1/4th of the total weight of the Prius powertrain. The hybrid plug-in concept is designed to accommodate a lithium-ion battery that would be rechargeable at home. The result is a vehicle with the possibility of traveling over 600 miles on a small four-gallon tank of fuel and achieving the acceleration performance that is equivalent to the Prius.
