First Image from Transformers 4 Teaser Trailer

Thanks to Feris O. here is the first image from the Transformers: Age of Extinction Super Bowl teaser trailer that is just hours away from release. It seems the robots alt mode is the green 2014 C7 Corvette Stingray. As for his name, speculation has narrowed it down to Crosshairs or Slingshot but still no official confirmation of names with alt modes (except for Prime and 'Bee of course). I wonder how a metallic cape works?
