What is the difference between an Audi A5 40 TDI and 45 TDI engine?

I am looking to purchase an Audi A5 but I am unsure about the differences between the 40 TDI and 45 TDI engines. Can someone please explain the distinctions between these two options?

The main difference between the 40 TDI and 45 TDI engines is their power output. The 40 TDI has a 2.0L engine with 201 horsepower, while the 45 TDI has a 3.0L engine with 261 horsepower.

In addition to the power difference, the 45 TDI also has a higher torque. This means it has better acceleration and can handle heavier loads.

Another key distinction between the two engines is the fuel efficiency. The 40 TDI has a higher mpg (miles per gallon) rating, making it a more budget-friendly option for long-term use.
