Tesla Model X or 3? Caught Testing [VIDEO]

Youtuber Juan del Real shot this video of a Tesla Model X being tested at the former naval air station in Alameda California about 30 miles north of Tesla's factory in Fremont.

Based on the size of the Model S in the background, Jalopnik think the camouflaged prototype looks too small to be a Model X and believe this may in fact be the first sighting of a Model 3.
