The Lunar X-Prize winning condition was "landing a robot on the surface of the Moon, traveling 500 meters over the lunar surface, and sending images and data back to the Earth."
The Falcon Heavy test payload was a Tesla Roadster with multiple cameras. The static engine test was one day after the X Prize Foundation announced nobody would claim the prize by the deadline, but launched 53 days before the deadline passed.
If Musk had wanted to win that prize, could he have done so with that payload? (Presumably telling the foundation that an attempt would be pending the result of the engine test so they didn't prematurely call an end to it).
If not, what further changes would the payload (/final stage) have required to win?
