What are the key differences between the Audi 80 and Audi 90 models?

I am currently looking to purchase a used Audi and I'm deciding between the Audi 80 or Audi 90. What are the main differences between these two models?

The main difference between the Audi 80 and Audi 90 is in the engine configuration. While the 80 model was equipped with a 1.8-liter 4-cylinder engine, the 90 model had a 2.0-liter 5-cylinder engine. Generally, the 90 model has better performance and acceleration than the 80 model.

In terms of design, the Audi 80 had a more traditional and conservative look compared to the sleeker and sportier design of the Audi 90. Additionally, the 90 model also had some exterior upgrades such as a rear spoiler and alloy wheels.

Both the Audi 80 and 90 models were available in both sedan and wagon body styles, but the 90 model also had a rare convertible option. If you are looking for a convertible option, the Audi 90 may be the better choice for you.
