The Mazda RX-9 concept 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, carry four full-size adults, and enjoy athletic performance. This vehicle concept is paired with Michelin Electro-active Polymer tire technology that takes full advantage of the efficient, electrically-boosted drivetrain.
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.
Michelin Electro-active Polymer tires 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 power from the hybrid engines' batteries and capacitor. This power activates the articulated treading that responds to changing road conditions.
Michelin E.A.P. tires are designed to "morph" from one mode to another when electricity is applied to the electroactive polymer that each tire is made of. This allows the tires' tread pattern to change shape and depth. The tires can then be optimized for various road conditions. / Michelin Design Challenge Winner 2006.
