Maybe, but with only a quick glance, I don't see any real "spoiling" of air flow taking place in the pics, related to my earlier intuitive definition of what a spoiler does.

I do see a "lip", which as has been discussed here elsewhere, helps the rear turbulent air behind the vehicle air reattach better to the rear airflow off the trunk lid.

I am not trying to open a semantics discussion, but believe clarity is important here.

On a historical note, I saw my first real spoiler on the winning 250 TR Ferrari at the 1962 Sebring 12 hrs. It was not intuitive as to its purpose or method at the time.
