Why do some Audi 80 models have a different body style compared to others?

I've noticed that some Audi 80 models have a more angular and aggressive body style while others have a softer and more rounded shape. What is the reason for this difference? Is it purely for aesthetics or does it serve a functional purpose?

The different body styles in Audi 80 models are due to different design decisions made by the company. Some models may have been designed to appeal to a certain audience or to evoke a specific image, while others may have been designed for practicality and aerodynamics.
