What is the efficiency of the Audi A2's regenerative braking system?

I've heard that the Audi A2 has a regenerative braking system. Can you explain how it works and how efficient it is compared to traditional brakes?

The regenerative braking system in the Audi A2 is a form of energy recuperation that converts the kinetic energy of the car into electrical energy. This energy is then stored in the car's battery and can be used to power the car's electrical systems, reducing the strain on the engine.

The efficiency of the regenerative braking system in the Audi A2 depends on various factors such as driving habits, terrain, and battery charge. However, studies have shown an average energy efficiency of about 65-70%, which is significantly higher than traditional braking systems.
