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

I am looking to purchase an Audi A7 but I am confused about the difference between the 45 TFSI and the 45 TDI engines. Can someone help clarify?

The main difference between the 45 TFSI and the 45 TDI is the type of engine. The 45 TFSI has a gasoline engine while the 45 TDI has a diesel engine. Both are efficient and powerful, but it ultimately depends on your personal preference and driving needs.

The Audi A7 45 TFSI and 45 TDI have similar performance and features, but the TDI engine offers better fuel efficiency and torque. If you prioritize fuel economy and towing power, then the 45 TDI may be the better option for you.
