What is the difference between Audi 80 and Audi 90 engines?

I am considering buying an Audi 80 or 90, but I am not sure about the differences in their engines. Can anyone provide some insight?

The main difference between the Audi 80 and Audi 90 engines is their size and power output. The Audi 80 typically has a 2.0L engine, while the Audi 90 has a 2.3L engine, resulting in a 16hp difference in power. The Audi 90 also has a slightly higher torque rating, giving it more acceleration potential.
