New movie, new cast, new Optimus Prime: Guess Michael Bay wasn't kidding when he said Transformers 4 would be different, and he's just given us a sneak peek at three new-look Autobot vehicles on his official website.

Optimus Prime has traded in his old parts for a slick Western Star model (an offshoot of Daimler), while his new friends include a Bugatti Grand Sport Vitesse and a C7 Corvette Stingray. They're looking seriously shiny, and ready for action.

Much and all as we're delighted to get a sneaky peek at the cars, we wouldn't mind a few cheeky snaps of our own Jack Reynor in action. The more we hear about this one, the more we get excited about a young Irish lad like himself being involved.

We just don't know how we'll have the patience to wait until June 27th 2014 now...
