How does the hybrid engine in the BMW i5 work?

I am interested in learning more about the technical details of the hybrid engine in the BMW i5. Can you provide an overview of how it works and any unique features it offers?

The hybrid engine in the BMW i5 combines a traditional combustion engine with an electric motor. This allows for increased efficiency and reduced emissions. The electric motor can also work independently, providing a more eco-friendly driving option.

One unique feature of the BMW i5's hybrid engine is the regenerative braking system. This captures energy that would normally be lost during braking and stores it in the battery, helping to extend the range of the electric motor.

In addition to saving fuel and reducing emissions, the hybrid engine also offers a smoother and quieter driving experience. This is due to the electric motor providing instant torque and working seamlessly with the combustion engine.
