What is the purpose of the Audi 80's torsion beam suspension?

I have noticed that many Audi 80 models have a torsion beam suspension instead of a traditional independent suspension. How does this type of suspension differ from independent suspensions and what benefits does it offer?

The torsion beam suspension in the Audi 80 allows for a more compact design and reduces the overall weight of the vehicle. It also provides better handling and stability compared to a traditional suspension system.

The main benefit of a torsion beam suspension is its cost-effectiveness. It requires less parts and is easier to manufacture compared to an independent suspension, which translates to a lower cost for the consumer.
