While the above vehicle has yet to transform, this robot in disguise will be one of at least two new additions to Michael Bay's Transformers 4.  Currently filming in Monument Valley, Transformers 4 stars Mark Wahlberg, Nicola Peltz and Jack Reynor, but the real draw are the massive autonomous fighting robots at the heart of the franchise.  Seen above is the $2.4 million Bugatti Grand Sport Vitesse, a 16-cylinder engine with quad turbochargers pumping out 1,200 horsepower.  While there's no word as of yet on just which Autobot this beast will transform into, you can bet it will be nasty.  Hit the jump for another new car that will make an appearance in Transformers 4.

Now this is pure conjecture on my part, but a Bugatti has served as the base model for the Transformer Smokescreen, as well as for Jazz and his twin brother Ricochet in the past.  Although, car models will vary between Transformers properties and toy lines, so it's hard to say just which Autobot this beast will be.  Any guesses?  Perhaps an entirely new Bot?

As for the second picture of the Chevrolet C7 Corvette Stingray - based on the company's 2014 model - we've seen this car before, both in Transformers: Revenge of the Fallen and in Transformers: Dark of the Moon.  The Autobot character Sideswipe - voiced first by André Sogliuzzo and then by James Remar - appears to have gotten a model upgrade and a new paint job, as long as the movies keep consistent.

Also starring Stanley Tucci, Kelsey Grammer and Sophia Miles, Transformers 4 is set to debut on June 27, 2014.

UPDATE: And here is the "upgraded, custom-built" Optimus Prime:
