Of all the concepts prepared every year for the Geneva Motor Show, those made by Rinspeed are typically the most outlandish and forward-thinking. And this is the latest from Frank Rinderknecht and company.

Though Rinspeed's been known to build entirely original vehicles from the ground up, it tends to base its creations on production models: Following the Tesla-based XchangE from last year, the Smart-basedDock+Go of 2012, the Fiat-based E2 from 2009 and the Lotus-based sQuba in 2007, the new Budii concept is based on the BMW i3. That means, of course, that it's powered by electricity, but the technology demonstrator is focused more on autonomous driving tech.

The Budii incorporates a periscopic camera and laser scanner to map the terrain and the road ahead from above, and a drive-by-wire steering system that allows the steering wheel on an articulated column to be passed between driver and passenger or tucked out of the way to let the electronics take over. Once unburdened of the task of driving, the occupants can enjoy the proliferation of touchscreens, the "wellness shower" (whatever that is) installed in the headliner, the automatic watch-winder on the steering column and the interior accoutrements furnished by Mansory.

The whole thing rides on a lowered suspension with 19-inch Borbet alloys, with a rainbow Knight Rider-style grille in the nose. But to appreciate the full scope of the consortium of suppliers that collaborated with Rinspeed to bring the Budii to life, you'll want to delve into the press release after the video below and scope out the dozens of high-resolution images in the slideshow above.
