Why does Audi have a single-frame grille and how does it affect the car's aesthetics?

I noticed that many Audi models have a feature called a 'single-frame grille', but I'm not sure what purpose it serves. Can someone explain its purpose and how it affects the overall look of the car?

The single-frame grille is a signature design element of Audi cars and serves as an air intake for the engine. This design choice also gives the car a more aggressive and sporty appearance.

Having a single-frame grille reduces the number of gaps and seams on the car's front, which improves aerodynamics and fuel efficiency. Plus, it's a sleek and modern design.

Audi actually introduced the single-frame grille in 2004 as a way to unite their various car models under one recognizable design element. It has since become a defining feature of their brand.
