9. sQuba

The "sQuba" was presented by Rinspeed at the Geneva Auto Show in 2008. It is known as the "world's first diving car." You just gotta watch the video for full comprehension and some ridiculous entertainment, but apparently this transformer can be submerged at depths of 33 feet and for some odd reason remains a convertible while your admiring the marine world. No worries though, you may get wet but at least you've got "futuristic Carbon Nano Tubes" to hold you and your pal safe secure in the vehicle and thir is a supply fresh air to breath from the self-contained on-board system.
