What is the difference between the Audi A4 35 TFSI and 40 TFSI engine?

I am a potential buyer of the Audi A4 and cannot seem to understand the difference between the 35 TFSI and 40 TFSI engine. Can someone explain the technical variations and any performance differences between these two engines?

The main difference lies in the power output and torque capabilities. The 40 TFSI has a higher power output and torque compared to the 35 TFSI, resulting in better overall performance and acceleration. However, the 35 TFSI is more fuel efficient, making it more suitable for those looking for a car with better fuel economy.

The main difference is the engine size. The 40 TFSI has a 2.0L engine while the 35 TFSI has a 1.4L engine. This leads to differences in power output and torque, with the 40 TFSI having more power and torque. Additionally, the 40 TFSI also has a higher fuel consumption compared to the 35 TFSI.
