Why does the Audi A6 have 4 doors instead of 2?

I notice that most sports cars have 2 doors, while the Audi A6 has 4 doors. Is there a specific reason for this, or is it just a design choice?

The reason for the 4-door design is to enhance practicality and make it more accessible for everyday use. This allows for easier access to the back seats for passengers and also makes it more functional for everyday tasks such as grocery shopping or hauling larger items. Additionally, the A6 is known for its luxury and comfort, and the extra doors add to the overall spaciousness of the car.

The 4-door design also allows for easier access to the front seats for the driver and passenger. This makes getting in and out of the car more convenient, especially for taller individuals who may have trouble maneuvering in and out of a 2-door car. It also adds to the overall convenience and comfort of the A6.
