What are the differences between the 2021 Audi A8 and the previous model?

I am considering purchasing a new Audi A8, but I'm not sure if I should go for the latest model or the one from the previous year. Can someone with knowledge on both models explain the differences in terms of design, features, and performance?

The main differences between the 2021 Audi A8 and the previous model can be seen in the design and technology updates. The 2021 model has a more angular and aggressive front grille, along with new OLED taillights and improved interior features.

From a performance standpoint, the 2021 Audi A8 comes with a new 3.0-liter turbocharged engine, which provides more power and better fuel efficiency compared to the previous model. It also offers new driver assistance features, such as predictive active suspension and rear-wheel steering.
