MichaelBay.com has posted another new car that is part of Transformers 4. From the site, "Unveiling yet another surprise . . . the extraordinary and exhilarating 2013 Lamborghini Aventador LP 700-4 Coupe. High resolution photo: http://bayhem.com/16OKk8T".

It is probably a safe bet to assume this is a Transformers alt mode, but for what character? Traditionally the Autobot Sideswipe was a red Lamborghini in his G1 incarnation but traditions can change. If sticking with G1, Decepticon Breakdown (member of the Stunticons) was based on a white Lamborghini Countach. Hopefully he will find out soon. Thanks to Sam N. for the heads-up.
