Italdesign's highly novel MPV is called the Structura. Based on the Audi A8, but designed to take VW's W12 engine, the car aimed to promote "the hidden side of design, the internal technological structure." With its lower door sections glazed and aluminum structure exposed for inspection, this see—through vehicle certainly does that. The windows are fixed for added rigidity because the designers regard opening windows as being unnecessary in the future; climate control will be highly efficient, and tolls will be paid electronically. The rear doors open only if those in front are opened first, and the vehicle has ten airbags.
