The RX-9 is configured to seat four passengers comfortably. It conveys the visual signature of a futuristic, two-door coupe. However, it incorporates two smaller rear doors (that deploy in a clamshell fashion) easing ingress and egress for rear passengers. The doors and inner doorframe are part of a larger internal structure that combines an aluminum space frame with composite exterior surfaces. The Mazda RX-9 is an exciting expression of the visual and functional possibilities of a new kind of grand touring car. A low-slung, two-plus-two vehicle motivated by a hybrid drive train, the RX-9 enables the driver to be environmentally conscious while allowing the full enjoyment of an athletic automobile. It is truly the world's first practical, and economical GT car.

Michelin E.A.P. is a tire system designed to take advantage of current and forthcoming advances in hybrid drive train technology. E.A.P. stands for Electroactive Polymer which are also known as artificial muscles for their functional similarity to natural muscles. E.A.P.s are plastic materials that change shape and size when a given voltage or current is applied.

Michelin E.A.P.s work in conjunction with the Mazda RX-9's hybrid drive train, electrostatic collectors, and onboard capacitor. The E.A.P. wheel and tire assembly draws voltage from the hybrid engines' batteries and capacitor. This voltage activates the articulated treading that responds to changing road conditions.

Michelin E.A.P.s are designed to "morph" from one mode to another when voltage is applied to the electroactive polymer that each tire is made up of. This allows the tires' tread pattern to change shape and depth. In this way, the tire can be optimized for various road conditions. / Michelin Design Challenge Winner 2006
