I found this info in an article written about the 2016 Cadillac ATS-V:
The enemy of a performance car - beyond speed cameras and over-zealous highway police - is heat, and Cadillac has left nothing to chance there. Every grille and vent has a purpose, and in fact the engineers had to get creative to accommodate every heat-exchanger they wanted to install.
So, there are eight heat-exchangers in total, along with an 850W cooling fan. Each of the “grillettes” - the lower side grilles - has an intercooler, linked with the main cooler for the engine. The auto transmission alone gets two coolers, one in the traditional place behind the grille, and another mounted flat on the underside, near the front, the only spot Caddy had left.
