Production rear spoiler reduced center height.

Is there some aerodynamic advantage to the reduced height of the center approximately 1/3 of the rear spoiler on recent Ford and Mopar products or is it just for better rear view mirror sight line?ok

I always figured those spoilers were mostly decorative.  I figured it's for increased visibility.  

Toyota Camry TRD has the same - I too figured it's to see out the back.

Looks like the corvette has something similar on some variants

Performance wise it is a thing at the pointy end of the scale. Think of it like a twisted wing to take better advantage of the local air angle of attack on a rear mounted wing. For a spoiler the ends are doing most of the work.

Styling/production wise it is a way to create a link to motorsport and reduce the number of long straight lines (anti-cyber truck). In the production world I bet ther was more than one discussion of the cost of tooling per car versus performance (drag reduction) when looking at simple versus complicated shapes.

I have personally witnessed the conversation about a more robust splash pan costing $0.05 more per vehicle and did it provide enough drag reduction to be worth the effort.

Thanks for the reply! Interesting information.

It looks like in that application it improves center rear brake light visibility it nothing else, mainly from a lawyers  POV?
