Why do some Audi A4 models have turbocharged engines and others do not?

I've noticed that some Audi A4 models have turbocharged engines while others do not. Can someone explain the differences between the two and why Audi offers both options?

Turbocharged engines provide increased power and efficiency compared to non-turbocharged engines. However, they may also have a higher cost and require more maintenance. It ultimately depends on your driving needs and budget.

The availability of turbocharged engines in the Audi A4 may also depend on the model year. Later models tend to have more options for turbocharged engines compared to older models.

Not all turbocharged engines are created equal. Some may have more horsepower and torque compared to others. Make sure to research and test drive different options to find the right fit for you.
