What is the difference between Audi 80 Quattro and non-Quattro models?

I've been browsing through used Audi 80s and noticed that some have the 'Quattro' badge while others do not. What exactly is the difference between the Quattro and non-Quattro models and how does it affect the driving experience?

The main difference between Quattro and non-Quattro models lies in their drivetrain. Quattro models have all-wheel drive, which provides better handling and traction in inclement weather conditions. However, this also means they are generally heavier and less fuel efficient compared to non-Quattro models.
