His dark materials

This is the BMW Gina. Ostensibly a two-seater roadster, it's actually more of a philosophical statement that has informed BMW's current production line-up and will influence future vehicles.

Built on the short-lived Z8 Roadster platform, the Gina consists of a flexible 'skin' stretched over a metal wire structure enforced with carbon fibre. It allows the driver to change the shape of the car 'on the fly' - the rear spoiler can be raised, for example, while the rocker panels can effectively be bodykitted out.
