What is the difference between an Audi A7 55 TFSI and 60 TFSI?

I am considering purchasing an Audi A7 but I am unsure of the difference between the 55 TFSI and 60 TFSI models. Can someone explain the technical differences between these two options and how they may impact the performance of the vehicle?

The main difference between the Audi A7 55 TFSI and 60 TFSI lies in their engine sizes and power output. The 55 TFSI has a 3.0-liter turbocharged V6 engine, while the 60 TFSI has a 4.0-liter twin-turbo V8 engine. This translates to a higher horsepower and torque in the 60 TFSI, resulting in a faster and more thrilling driving experience.
