What is the difference between Audi A8 50 TFSI andAudi A8 60TFSI?

I am interested to know the difference between Audi A8 50 TFSI and Audi A8 60 TFSI models. Both of these are in the same category but do they differ in any way performance-wise or features-wise?

The main difference between Audi A8 50 TFSI and Audi A8 60 TFSI lies in their engine sizes and power output. The A8 50 TFSI comes with a 3.0-liter V6 engine while the A8 60 TFSI is equipped with a larger 4.0-liter V8 engine, resulting in a higher horsepower and torque output for the latter model.
