The Audi A8 50 TDI has a V6 diesel engine, while the Audi A8 55 TFSI has a V6 petrol engine. If you're looking for better fuel efficiency, the diesel engine may be the better option.

The 55 TFSI has a higher horsepower and torque than the 50 TDI, providing a more powerful and responsive driving experience. However, the 50 TDI has a higher fuel economy rating.
