What is the hybrid system in an Audi A2 and how does it work?

I've heard that the Audi A2 has a hybrid system, but I'm not sure how it operates. Can you explain it to me in simple terms?

The Audi A2 features a parallel hybrid system, meaning it has both an electric motor and a traditional combustion engine. This allows for better fuel efficiency and reduced emissions. To put it simply, the electric motor provides additional power to the engine when needed, such as during acceleration or going up hills.
