What is the difference between Audi A1 30 TFSI and 35 TFSI engines?

I am trying to decide between the Audi A1 hatchback 30 TFSI and 35 TFSI engines. Can someone explain the difference between these two engines in terms of performance, fuel efficiency, and reliability? I want to make the most informed decision before making a purchase.

The Audi A1 30 TFSI engine has a displacement of 1.0L while the 35 TFSI has a displacement of 1.5L.

In terms of performance, the 35 TFSI has a higher horsepower and torque output than the 30 TFSI.

However, the 35 TFSI also has a higher fuel consumption rate compared to the 30 TFSI. It ultimately depends on your priorities and driving habits.
