There's an order of a magnitude difference (at least) between different, real-world cars particularly when you'll be driving one around versus fictional terminology that differs in a SF show that has no bearing on reality (particularly when the difference was in a one off that occurred extremely early in production)..
They have set the expectation, they have sold it to us, if they don't deliver some folks will be disappointed.
Though it doesn't matter to me as I'm just treating it as its own thing and will judge it accordingly.
