The designers get a lot of freedom to experiment, but it is often challenging to create an interesting concept. To to do this, they look anywhere for inspiration.
Toyota turned to music culture as their source when developing their latest concept for the young adult market. This mini-van serves a dual purpose, transforming into a DJ's sound-stage.

Others look elsewhere. Earlier this year, Renault introduced the Fluence, a sports coupe concept. It's the interior where most of the innovation lies; from the video-game derived joystick driving controls, to the seats of the car that unfold like fans when the doors open. The inspiration for this idea came from the natural world. To understand how the seat might work, the designers looked at flowers to learn how petals open. They did this by going back to science class and watching time-lapse films and looking at petals under microscopes.
