How does the engine of an Audi 80 differ from other Audi models?

I've heard that the Audi 80 has a different engine setup compared to other Audi models. Can someone explain the specifics of this difference?

The Audi 80 actually has a longitudinal engine setup, while most other Audi models have a transverse setup.

This design change was implemented to improve handling and performance, making the Audi 80 a more agile and responsive vehicle.

In terms of maintenance, the longitudinal engine setup can make it a bit more time-consuming and expensive to work on compared to the transverse setup.
