[[WP:NOT]] a crystal ball says "scheduled or expected future events should only be included if the event is notable and almost certain to take place".

At this point, given the lack of reliable sources (and the equivocating by the more reliable sources), it's impossible to say for certain that the car will be released in the future.

[[WP:NOT#Wikipedia_is_not_a_crystal_ball|NOT a crystal ball]] says that articles on future events/products should only be kept if the event is "almost certain to take place".  Given that this car's release has never been certain, (no semi-[[WP:RS|reliable sources]] talked about its release with any certainty) the article could probably have been deleted long ago.  --~~~~
