I think it's exactly the same. The Hotwheels plastic model is just a crude representation.
Yeah, but crude representations (which it is - Hot Wheels is no FFG!), tend to lose detail, not add what's not there...
For example, look at the detailing behind the R2 unit - it's a low detail "short hand" for the detail you'd normally find on an X-Wing ... looks, kinda of right, captures the "essence" of what should be there.
Now look at the detailing beside the engines on the wing ... there's extra detail that whole panel gets another raised panel on top with holes all over it. They went out of their way there to add detail that is just not there on an X-Wing.
