What is the difference between Audi A7's 55 TFSI and 50 TDI engines?

I am trying to decide between the Audi A7's 55 TFSI and 50 TDI engines. Both seem to have similar specs, but I am not sure which one would be the better choice. Can someone explain the main differences between the two engine options?

The main difference between the 55 TFSI and 50 TDI engines in the Audi A7 is the fuel type. The 55 TFSI engine runs on gasoline while the 50 TDI engine runs on diesel. Generally, gasoline engines tend to offer better performance while diesel engines are more fuel-efficient.

Another difference between the 55 TFSI and 50 TDI engines is the power output. The 55 TFSI has a higher horsepower and torque, which means it offers quicker acceleration and a more dynamic driving experience. The 50 TDI, on the other hand, has slightly lower power but better fuel economy.
