Two Different 2014 CTS Mules?

[Rob]

Scroll over the picture below and take a close look at the two 2014 CTS test mules. Pay close attention to the front grilles and the mirrors. Possibly a 2014 CTS-V mule in the back?

Maybe. Maybe not.
The one in the back has an extra set of vertical grill openings. GM just might be testing 2 different standard grills to see which works better in summer testing.
