What is the difference between the Audi A7 45 TFSI and the Audi A7 55 TFSI?

I am considering purchasing a new Audi A7, but I am unsure of the difference between the 45 TFSI and the 55 TFSI models. Can someone please clarify?

The main difference between the Audi A7 45 TFSI and the 55 TFSI is the engine size and power. The 45 TFSI has a 2.0-liter four-cylinder engine with 248 horsepower, while the 55 TFSI has a larger 3.0-liter V6 engine with 335 horsepower. If you're looking for a more powerful and responsive ride, I would recommend the 55 TFSI.

In addition to the engine, the Audi A7 55 TFSI also includes more premium features such as a Bang & Olufsen sound system and a heads-up display. If these features are important to you, I would recommend opting for the 55 TFSI model.
