If you are going to do a concept car, then at least make it wacky. At least, that seems to be the French way of thinking. This large one-box wagon-cum-minivan brings slinkiness to a market where the Chrysler Pacifica settled for safety. The C-Airlounge is a roomy four- or five-seater with a low, low drag coefficient of 0.26 and a semi-active suspension. Inside, occupants can use light projected by optic fibers and video projectors in the carpet and armrests to change the interior ambience from clinical to baroque colors.
