What is the difference between the Audi A7 55 TFSI engine and the Audi A7 50 TDI engine?

I'm interested in buying an Audi A7, but I'm not sure which engine option is better for me. Can someone explain the main differences between the 55 TFSI and 50 TDI engines in terms of performance, efficiency, and cost?

The Audi A7 55 TFSI engine is a gasoline engine with a 4-cylinder turbocharged engine that delivers 248 horsepower and 273 lb-ft of torque, while the Audi A7 50 TDI engine is a diesel engine with a 6-cylinder turbocharged engine that produces 282 horsepower and 457 lb-ft of torque. It really depends on your driving preferences and budget.

In terms of fuel efficiency, the A7 50 TDI engine has a higher mpg rating compared to the A7 55 TFSI engine. However, the 55 TFSI engine has a quicker 0-60 mph acceleration time. So if you prioritize power and speed, go for the 55 TFSI engine.

The cost difference between the two engines is not significant, but the diesel option may require additional maintenance and repairs in the long run. If you drive long distances frequently, the 50 TDI engine may be a better choice for you.
