What is the difference between Audi A8 variant 55 TFSI and 50 TDI?

I'm considering buying an Audi A8 but I'm unsure about the differences between the 55 TFSI and 50 TDI variants. Which one would suit my needs better?

The main difference between the 55 TFSI and 50 TDI variants is the type of engine they have. The 55 TFSI has a 3.0-liter V6 engine, while the 50 TDI has a 3.0-liter V6 diesel engine. If you value fuel efficiency and lower emissions, the 50 TDI would be a better choice.

While the 55 TFSI offers a more powerful and smoother driving experience, the 50 TDI provides better torque and can be a more suitable option for drivers who prioritize towing or hauling heavy loads.

Another key difference between the two variants is the type of transmission. The 55 TFSI has a 7-speed automatic transmission, while the 50 TDI has an 8-speed automatic transmission. The 50 TDI's extra gear can result in improved performance and fuel economy.
