What is the difference between the Audi A5 and its Sportback model?

I am torn between buying the Audi A5 coupé or the Sportback. What are the distinguishing factors between these two models in terms of performance, features, and pricing?

The Audi A5 is a classic and sleek coupé, designed for pure performance and driving pleasure, while the Sportback model is a practical and versatile five-door hatchback version that offers more interior space. Both models have similar performance specs and features, but the Sportback may have a slightly higher price point due to its added functionality.
