The rendering you see here was created by an organization called goldRush Rally, which published the image on its Facebook page. The claim is that this rendering was based on a "snapshot of a plaque with a sketch of the new supercar." We certainly won't speculate as to what kind of "presentation" a luxury-rally throwing company like gRR would be invited to – to say nothing of why there was a plaque bearing the image of a supercar that has been so well cordoned off from public eyes – but we'll roll with it because we love the internet.
Even if the story is completely true (big if), we're fairly certain the details of the rendering miss in some places relative to the real deal car. The front wheel wells, for instance, seem comically thin around the top, and hold wheels that are way out of proportion with the spy shots and videos we've seen so far. More promising, however, is the detailing of the door and sill of the F150 – portions of the car that have consistently been covered in spy shots.
For what it's worth we're virtually certain that the source photograph for this rendering was taken in front of the Maranello Palace hotel just down the street from the Ferrari factory, and likely started as one of the many F150 test mules that have been photographed there. One small win for authenticity, at least.
