There are numerous elements of the 2011 Citroen Tubik concept that are inspiring. The nose itself is very chic, and sets the tone for the Tub’s wild, semi-spherical curving panels.

White gloss effect acrylic forms the entire nose and tail of the machine, but the central section is a floating layer of stainless steel.

The idea has aero principles, recalls Apple’s best product designs, and is a fresh take on the corrugated steel panels of the original Type H vans from the 1930s.

The interior, like many French concepts, completely drops the ball.

It is far too space-age, with silly purple velour everywhere, un-produce-able seating with no seat belts, and no real dashboard. It makes clear that this van concept is a million miles from showrooms.

This is a shame because it makes the exterior, which is very production-friendly, seem just as far-fetched.

The Tubik’s flowing panel shapes have carried onto production models, but offer none of the clean, future-tech style of this simple work-van shape.

The side windows are fantastic, with ability to change from a mirror finish, to dark tinted glass, and to clear glass via electric particles in the glass.
