This is the EDAG Light Cocoon, not a proper, working car but a concept shown at Geneva that demonstrates just how little material you actually need to make a functioning vehicle.
The whole structure of the car, which is said to be inspired by bat's wings and leaves, has been 3D printed, meaning that only as much material needed is used, eliminating the waste that comes with metal stamping and pressing, and also making sure that the structure can be strong without being heavy.
Over that is then stretched a durable, waterproof fabric designed for EDAG by clothing maker Jack Wolfskin. Although it's weather proof, this stuff is seriously lightweight too - at just 19-grammes per square metre, it weighs about a quarter as much as an equivalent amount of photocopier paper...
All of that is then lit from within by LED lights, emphasising the light and simple layout of the car.
"We are pursuing the vision of sustainability - as demonstrated by nature: lightweight, efficient and without any waste," said EDAG's head designer Johannes Barckmann. "The EDAG Light Cocoon presents a stable, branch-like, load-bearing structure from the 3D printer, which uses material only where it is absolutely necessary."
