What is the difference between Audi A3 variants 30 TFSI and 35 TFSI?

I'm trying to decide between the Audi A3 variants 30 TFSI and 35 TFSI. What are the main differences between these two options and which one would be a better choice for me?

The biggest difference between the Audi A3 30 TFSI and 35 TFSI is the engine size. The 30 TFSI comes with a 1.0-liter engine while the 35 TFSI has a larger 1.5-liter engine. If you want more power and stronger acceleration, the 35 TFSI is the way to go. But if fuel efficiency is a priority for you, then the 30 TFSI may be a better choice.
