Why does the Audi 80 have a longer wheelbase compared to other sedans in its class?

I've noticed that the Audi 80 has a slightly longer wheelbase compared to other sedans in its class. Can someone explain why this is and what benefits it provides?

The longer wheelbase in the Audi 80 allows for better weight distribution and improved handling, resulting in a smoother and more stable ride.

In addition to better handling, the longer wheelbase also provides more legroom and cabin space, making it a more comfortable and spacious option for passengers.

The longer wheelbase in the Audi 80 also contributes to better aerodynamics, resulting in improved fuel efficiency and performance.
