What are the differences between the Audi A6 2021 and the previous model?

I'm considering buying a new Audi A6, but I'm not sure what has changed from the previous model. Can anyone shed some light on this?

The 2021 Audi A6 has a few notable updates, including a refreshed exterior design, improved technology features, and a more powerful engine. It also has a new high-performance S6 trim level for those seeking a more sporty driving experience.

I recently purchased a 2021 Audi A6 and have been very impressed with the new technology features, especially the virtual cockpit and updated infotainment system. Overall, I highly recommend it.
