What is the difference between Audi A7 45 TFSI and 55 TFSI engine?

I'm trying to decide between the two engine options for the Audi A7 and I'm wondering what the main differences are in terms of performance, fuel efficiency, and overall driving experience.

The Audi A7 45 TFSI has a 2.0-liter turbocharged 4-cylinder engine, while the Audi A7 55 TFSI has a 3.0-liter turbocharged V6 engine. In terms of performance, the 55 TFSI offers more horsepower and torque, resulting in a quicker and more dynamic driving experience. However, the 45 TFSI is more fuel-efficient, making it a better option for those looking for a more economical choice.

Both engines offer strong performance, but the 55 TFSI takes it to the next level with its available sport differential and adaptive damping suspension. These features provide better handling and a more responsive driving experience. If you prioritize power and handling, the 55 TFSI is the way to go.
