In photo's of the Panamera Turbo and the GTS, there is what looks to be a camera located in the front bumper? I know with part assist there is one in the rear, but what is this lens looking part in the front bumper?

 

I think its the adaptive Cruise control

 

It is.

 

I purposefully bought a PTT without that option after reading all the negative remarks about how it works poorly. Camera looks cool though

 

Personally, I LOVE the adaptive cruise control! Especially on the interstate on long trips. It works awesome; maybe twice it has braked more than it should have when a car ahead of me pulled into a left turn lane; otherwise it has been flawless.
