Forgive the cluelessness of this question, but I was in my 20s when Transformers came out as a children's cartoon with a cool toy line. So I'm not familiar with the canon of this franchise.
I remember a few years ago a big to-do about a wreck on the set of a Transformers movie and that the Autobot named Bumblebee was a camaro in car form. (And easily totaled out as a stunt car, but I digress.) Now in this new movie he's a vintage VW Beetle. Can a transformer transform between different types of cars as well as between car and robot?
