What are the key differences between the Audi A4 and A4 Premium?

I'm thinking of purchasing an Audi A4, but I'm not sure what the difference is between the regular A4 and the A4 Premium. Are there any significant differences in terms of features and performance?

The main difference between the Audi A4 and A4 Premium is the level of luxury and technology offered. The A4 Premium includes features such as a panoramic sunroof, virtual cockpit, and leather seats, while the regular A4 does not.

In terms of performance, the A4 Premium offers a more powerful engine and sportier suspension for a more dynamic driving experience. However, it also comes at a higher cost.
