What is the difference between Audi A4 40 TFSI and 45 TFSI?

I'm interested in purchasing an Audi A4 and I noticed there are different versions such as 40 TFSI and 45 TFSI. What is the difference between them and which one would you recommend?

The main difference between the Audi A4 40 TFSI and 45 TFSI is their engine size and power. The 40 TFSI has a 2.0L engine with 188 horsepower while the 45 TFSI has a 2.0L engine with 248 horsepower. I would recommend the 45 TFSI if you want more power and performance.

In addition to the engine size and power, the Audi A4 40 TFSI has a front-wheel drive system while the 45 TFSI has Audi's famous Quattro all-wheel drive. If you live in an area with inclement weather, I would recommend the Quattro system for better traction and control.
