Why is the Audi R8 considered a 'supercar'?

I've heard people refer to the Audi R8 as a 'supercar', but I don't understand why. What makes it different from other luxury cars?

The Audi R8 is considered a 'supercar' because of its high performance capabilities. It has a powerful engine, advanced suspension and braking systems, and a lightweight construction. These features allow it to reach top speeds and handle corners like a true supercar.

In addition to its performance, the Audi R8 also has a luxurious and exotic design. Its sleek silhouette, aggressive grille, and signature LED headlights give it a bold and unique appearance that sets it apart from regular luxury cars.
