Batman Forever-style Batmobile, your Tumbler's up on blocks in the front yard, and you're itching for a new project. It's not too early to start planning a DIY version of Gordon Murray's newly unveiled Bat-ride (part of the Batman Live World Arena Tour). The designer drew on his experience with the McLaren F1 for his new concept car, which includes a healthy dose of imagineering: there's a carbon-fiber body that "breathes," as well as LED-lit "virtual wheels." We're not sure how carbon fiber breathes or what virtual wheels are, but as Murray explains in the video below, they're based on Formula One materials as he imagines them 15-20 years from now. He also envisions a greener Dark Knight, whose ride runs on hydrogen fuel cells and lithium-ion batteries -- no longer will the caped crusader suffer a guilty conscience due to his excessive carbon dioxide emissions.
