The Rinspeed BamBoo represents a concept car which will be revealed by the Swiss company at the 2011 Geneva Motor Show which will run from March 3rd to 13th.
The Rinspeed BamBoo is a ‘grown-up golf cart’ and as the name suggests, many of its interior components are made from bamboo fibers. However this is not some kind of weight saving measure, as the idea behind the Rinspeed BamBoo was to create an open top vehicle, light and easy to maneuver, reminiscent of the 70s for people who love the summer and the beach.
Despite its retro appearance, the Rinspeed BamBoo features an electric drive, however nothing that is directed towards ridiculous amounts of power. 
More details with the Rinspeed BamBoo at the time of the show.
Rinspeed press release :
Car Visionary Rinderknecht’s Focus at the Geneva Motor Show 2011 is on Back to the Roots
The names of the concept cars from Swiss car visionary Frank M. Rinderknecht are more than marketing-driven slick onomatopoeia that polls well with focus groups. At Rinspeed names often have a deeper meaning.  That is also true for the latest creation from Rinderknecht. “BamBoo” is the name of his latest ‘baby’ that resembles a grown-up golf cart and is bound to evokes plenty of admiration at the next Geneva Motor Show which runs from March 3rd through 13th, 2011.
Nomen est omen – the name says it all – is immediately apparent: Many interior components are made from bamboo fibers. But the four-seater “BamBoo” takes it to a whole new level – to the Meta level so to speak: This open-top vehicle awakens the longing for sun, summer, for lightness and easiness, the desire to be at the beach. It is a reminiscence of the Seventies, of the south of France and St. Tropez. And one would expect to find Brigitte Bardot behind the wheel with playboy Gunther Sachs at her side heading towards Tahiti beach..
Anyone who might think that this is simple retro design for nostalgia’s sake underestimates the boss of the Swiss concept powerhouse. Yes, Rinderknecht incorporates the automobile references of the time. But he doesn’t leave it at that. He reinterprets them and evolves them into the future. And he focuses in them the yearning to get back to the roots, paired with the absolute desire to be in harmony with creation. That makes electric drive, also for the onboard foldable two wheeler for the last “mile”, a must.
Anyone not blinded by horsepower orgies, chrome tinsel and top-speed frenzy should take a closer look. “BamBoo” pushes the ‘reset’ button, clears the mind for a new way of thinking. It sports simple, clean lines. No bells, no whistles.  Nothing is superfluous. Plain aesthetics in their purest form. As stated before and even in a figurative sense: Nomen est omen. Simply bamboo.
