What are the main differences between the 2019 and 2020 Audi A8 models?

I am looking to buy an Audi A8, but I'm unsure if I should go for the 2019 or 2020 model. Can someone explain the key differences between the two?

The main difference between the 2019 and 2020 Audi A8 models is the technology. The 2020 model features upgraded infotainment, including a larger touchscreen and improved voice recognition. It also comes with advanced safety features such as lane departure warning and automatic emergency braking.

Another significant difference is in the engine. The 2019 Audi A8 is equipped with a V6 engine, while the 2020 model comes with a V8. This results in a more powerful and smoother driving experience in the 2020 model. However, it also comes at a higher cost.
