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

I am considering purchasing an Audi A7, but I am unsure of the difference between the TFSI and TDI models. Can someone provide some insight?

The main difference between the A7 TFSI and TDI models lies in their engines. TFSI stands for turbocharged fuel stratified injection, meaning it has a gasoline engine with turbocharging and direct injection. On the other hand, TDI stands for turbocharged direct injection and refers to the diesel engine. So, it ultimately depends on your preference in terms of fuel type!

Apart from the engine, the other major difference between the A7 TFSI and TDI models is their fuel efficiency. In general, TDI diesel engines offer better fuel economy compared to TFSI gasoline engines. However, TFSI engines have been improving and their fuel efficiency is now comparable to TDI engines. Consider your driving habits and the availability of diesel fuel before making a decision.
