Director Michael Bay took to his official website today to reveal yet another version of Bumblebee in Transformers 4. Back in May, the director posted a photo featuring the 1967 Camaro SS version of this yellow Autobot, with today's shots showcasing a 2014 Concept Camaro that will also be used in his sci-fi action sequel. It seems possible that the filmmaker will take a page out of his original Transformers movie, with Bumblebee starting out as an older car before using his powerful technology to transform into a newer model. At any rate, take a look at the photos, along with the description from Michael Bay's website.
