Technically inaccurate, as others pointed out, but I would have been surprised if they kept BFR as a name. Yes, it includes the joke of "Big F..alcon Rocket", but it sounds very technical and it doesn't carry the appeal like e.g. Falcon does. And whilst some may disagree, I think Musk very much cares about how his products and companies are perceived.

But it won't even go to other stars!

You only say that so we'll have a Jefferson Starship.
