The EDAG Light Cocoon will be the German design consultancy firm's main concept car at the 2015 Geneva motor show, which will be held in March.

EDAG, whose name stands for Engineering and Design AG, wanted to create a body structure that did without any material that wasn't absolutely necessary. This lead the company to pattern the Light Cocoon's construction on that of a leaf.

According to Johannes Barckmann, EDAG's head designer, the Light Cocoon concept uses "a stable, branch-like load bearing structure from the 3D printer, which only uses material where it is absolutely necessary".

The consultancy performed a whole range of static and dynamic calculations and simulations to figure out what the optimal structural design would be for a coupe-style car. Once that was completed, EDAG approached clothing company Jack Wolfskin to supply a weatherproof outer skin that would be stretched over the car's under-structure.

EDAG claims that the Jack Wolfskin-supplied covering weighs a mere 19 grams per square metre, and is about four times lighter than the standard type of paper used in photocopiers.

The company has also fitted a backlight to highlight the car's minimalist web-like structure and tightly stretched translucent skin.
