How is the torsion bar in an Audi 80 different from other suspension systems?

I've read about torsion bars in cars, but I'm not clear on how they work in the Audi 80. Can someone explain how it differs from other suspension systems and any potential pros and cons?

The main difference between the torsion bar in an Audi 80 and other suspension systems is that it uses a twisting motion to create the necessary spring force, instead of using traditional coil springs. This allows for a more compact suspension system and can improve handling and stability. However, the torsion bar can be more difficult to adjust and may require some specialized tools.
