What are the differences between Audi A3 45 TFSI and 40 TFSI?

I am considering buying an Audi A3 but I am unsure about the difference between the 45 TFSI and 40 TFSI models. Can someone explain the distinguishing factors and which one would be a better choice?

The main difference between the two models is the engine size and power output. The 45 TFSI has a larger 2.0-liter engine and produces 228 horsepower while the 40 TFSI has a 1.4-liter engine and produces 147 horsepower. It really depends on your personal preference and how much power you want from your vehicle.

Another difference is the fuel efficiency, with the 40 TFSI getting slightly better gas mileage due to its smaller engine size. However, the 45 TFSI offers more torque which can be beneficial for a smoother driving experience.

When it comes to price, the 40 TFSI is more budget-friendly while the 45 TFSI is a bit pricier. If you want a more affordable option, go for the 40 TFSI. If you prioritize power and don't mind spending a bit more, the 45 TFSI may be a better fit.
