Getting in on the "Green" theme of the Frankfurt Motor Show (or is that nearly every show now-a-days?), Fiat is unveiling the Panda Aria concept, which comes packing plenty of eco-friendly technology both inside and out.

Motivation comes courtesy of an 800cc turbo'd two-cylinder engine that produces 80 HP, which can run on either gasoline or a methane-hydrogen mixture, plus it comes equipped with the oh-so-en vogue start-stop technology. Both the interior and exterior are comprised of a number of ecological materials, from the upholstery to the body panels, most of which is either recycled or recyclable.

You can get all the details in Fiat's press release after the jump.
