Why does the Audi A8 utilize a split-frame grille design?

I've noticed that the Audi A8 has a unique grille design, with the frame split in half. What is the purpose of this design choice and what benefits does it provide?

The split-frame grille design on the Audi A8 serves both an aesthetic and functional purpose. On the surface, it gives the car a distinct and stylish look, setting it apart from other luxury sedans. However, the split-frame also allows for better air flow to the engine, improving overall performance and efficiency. Personally, I find it to be a subtle yet eye-catching touch on an already impressive vehicle.
