How does the hybrid engine work in an Audi A2?

Can you explain the mechanics and operation of the hybrid engine in an Audi A2? What makes it different from traditional engines?

The Audi A2 uses a parallel hybrid engine, which uses both an electric motor and a gasoline engine to power the car. When the car is running at low speeds, the electric motor is the primary source of power, and the gasoline engine kicks in at higher speeds for increased performance.

The hybrid engine in the Audi A2 is able to charge itself through regenerative braking, meaning that the car can recover some of the energy used during braking and use it to power the electric motor. This leads to increased fuel efficiency and lower emissions.
