What does the Audi A2 hybrid engine consist of?

I'm looking to understand the specific composition of the Audi A2's hybrid engine. Can anyone break it down for me?

The Audi A2 has a parallel hybrid system, meaning it can be powered by both its electric motor and its 1.4L internal combustion engine. This allows for greater fuel efficiency and lower emissions.

The A2's hybrid engine also includes regenerative braking, where kinetic energy from braking is captured and stored in the battery for later use. This helps recharge the battery while driving and maximizes the car's efficiency.

In addition to the motor and combustion engine, the A2's hybrid system also includes a clutch and a synchromesh transmission to seamlessly switch between power sources and provide a smooth driving experience.
