What is the function of the hybrid system in an Audi A4?

I am interested in purchasing an Audi A4, but I am unsure of the purpose of the hybrid system. Can you provide some insight into how it works and if it is beneficial for daily driving?

The Audi A4's hybrid system uses a combination of an electric motor and a gasoline engine to power the car. This allows for improved fuel efficiency and reduced emissions. I personally find the system very useful for city driving as it automatically switches between the electric and gasoline power depending on the driving situation.

The hybrid system in the Audi A4 also has a regenerative braking feature, which captures energy that would normally be lost during braking and stores it in the battery. This helps to improve the overall efficiency of the car and reduce fuel consumption. I have noticed significant savings in my fuel expenses since purchasing the A4.
