But there's another sub project in the works for Tesla's superstar CEO.

Some years ago, the famous James Bond submarine that appeared in "The Spy Who Loved Me" was purchased at auction by Tesla Motors CEO Elon Musk.

For $866,000, Musk got a functioning sub. Actually, it's little more than a white Lotus Epirit with some fins glued on that's capable of moving underwater.

Right now, if deployed in the water, Musk's sub would reportedly function as a wet sub (meaning the driver would require a breathing apparatus).

Basically, it's a movie prop and nothing more. Heck, it can't even transform from car to sub, as it appears to do in the movie. And it will not move by itself on the pavement.

As Musk told the press back then:

"I was disappointed to learn that it can't actually transform. What I'm going to do is upgrade it with a Tesla electric powertrain and try to make it transform for real."

Well, apparently that idea was too far-fetched. His Lotus sits today the same as it did when he purchased it years ago.
