What are the key differences between the 2021 Audi A5 and its previous model?

I am looking to purchase a new Audi A5 but want to know how it differs from the previous year's model. Can anyone give me a breakdown of the main changes and updates?

For the 2021 model year, the Audi A5 has received a facelift with updated front and rear bumpers, a new grille design, and updated LED headlights.

The engine options have also been updated with a more powerful 2.0-liter turbocharged four-cylinder engine now standard on all trims, delivering 261 horsepower and 273 lb-ft of torque.
