What are the differences between the Audi A4 40 and 45 TFSI?

I am considering buying an Audi A4 and I am unsure about the differences between the 40 and 45 TFSI models. Can someone explain the technical differences and which one would be a better option?

The main difference between the 40 and 45 TFSI models is the engine. The 40 TFSI has a 2.0-liter four-cylinder turbocharged engine, while the 45 TFSI has a more powerful 2.0-liter four-cylinder turbocharged engine with a higher output and torque. If you want a better performance and acceleration, the 45 TFSI would be the better option.

Besides the engine, the 45 TFSI also comes with standard Quattro all-wheel drive, while the 40 TFSI only has front-wheel drive. This can make a difference in handling and traction, especially in adverse weather conditions. If you want better control and stability, the 45 TFSI would be a better choice.
