What is the difference between the Audi R8 TFSI and TDI models?

I am trying to decide between purchasing the Audi R8 TFSI or TDI models, but I am unsure of the major differences between the two. Could someone explain the distinctions in terms of performance, fuel efficiency, and overall driving experience?

The main difference between the Audi R8 TFSI and TDI models lies in their respective engines. The TFSI model features a gasoline-powered engine, while the TDI model has a diesel-powered engine. In terms of performance, the TFSI offers a higher horsepower and quicker acceleration, while the TDI offers better fuel efficiency. It ultimately comes down to personal preference and driving preferences.
