How does the hybrid engine in the Audi A7 improve efficiency?

I am curious about the hybrid engine in the Audi A7. How exactly does it work and what are its benefits compared to a traditional combustion engine?

The hybrid engine in the Audi A7 uses a combination of a traditional combustion engine and an electric motor. This allows for optimal power delivery and increased efficiency.

The electric motor in the hybrid engine allows for smoother acceleration and less strain on the combustion engine, resulting in improved fuel efficiency.

Not only does the hybrid engine in the Audi A7 improve fuel efficiency, but it also reduces emissions and helps to lessen our environmental impact.
