A car covered with cloth is something you would associate with the Flintstones, not the cutting edge of 21st century automotive design.
But BMW's latest concept car is exactly that - and it can change shape at the touch of a button.
The Gina - which at first glance looks like any other flashy sports car - is encased in fabric instead of metal panels.
Stretch limo: BMW's latest concept car has a cloth skin instead of metal
Open the door and the slinky fabric creases and wrinkles like skin.
Turn on the headlights and the covers peel up like giant eyelids - designed to make the sporty roadster more aerodynamic.
And its seamless skin - a single piece of durable fabric - can be morphed at the flick of a switch to suit its owner's mood, offering an aggressive or classic look.
BMW's Christopher Bangle said: 'This revolutionary solution opens up new design and production potential.
'The outer skin can move and do things a metal skin couldn't do.'
The German car maker's pioneering vehicle is based on the chassis of a BMW Z8.
Open sesame: The car doors wrinkle and the bonnet opens like a doctors' bag
Its skin is made of a silver expansion-resistant textile which stretches across movable metal wires controlled by hydraulics. The Gina (Geometry and Functions In Adaptions) has no bonnet, roof or boot.
Instead, a single sheet of cloth is layered over its frame, cocooning the driver in the ultra-modern cabin.

'The high-precision fit of the material to the metal mesh also allows surface changes without slackening the tension,' a spokesman said.
'It has a major impact on the interaction between driver and car and enhances it by offering a variety of entirely new options.'
Shut eye: Fabric 'eyelid covers the headlights
There is no need to lift the bonnet to get a look at the engine of this flexible motor - it opens from the centre like Hulk Hogan tearing off his T-shirt.
Opening and closing is similar to the mechanism on a doctor’s traditional medical bag, where clip-lock fasteners are held together in the middle by a rail.
