How does the Audi A7's hybrid system work?

I'm considering purchasing an Audi A7 and I've heard it has a hybrid system. Can you explain how this system works and if it is worth the extra cost?

The Audi A7's hybrid system combines a traditional gasoline engine with an electric motor. This allows the car to switch between power sources for increased efficiency. When driving at lower speeds or in stop-and-go traffic, the electric motor can power the car, reducing fuel consumption.

The hybrid system in the Audi A7 also has a regenerative braking feature, which recaptures energy that would normally be lost during braking and stores it in the battery. This allows the car to use more electric power and less gasoline, further increasing fuel efficiency.

It's also worth noting that the hybrid system in the Audi A7 adds a significant amount to the overall cost of the car. Whether or not it's worth it for you depends on your driving habits and willingness to pay for increased efficiency.
