We're getting closer and closer to being able to download cars. Case and point: this teeny tiny Ariel Atom, made in a 3D printer.

The standard has been raised in the world of bonkers motoring. Behold, the Ariel Atom 500. The Honda inline-four is replaced by a naturally-aspirated 500-hp 3.0-liter V8. Considering the Atom's slightly heavier than an eyelash, this will be spectacular. Updated.

Want to outrun Bugatti Veyrons in an open-wheeled roadster? It'll cost you at least $160,000. But with a 0-60 time of 2.5 seconds, with the Ariel Atom V8, you'll at least be getting your money's worth.
