What is the efficiency of the Audi A8's hybrid engine?

I am considering purchasing an Audi A8 with a hybrid engine. I want to know how efficient this system is and if it will save me money on fuel costs. Can anyone provide me with more information about the overall efficiency of this engine?

The hybrid engine in the Audi A8 is quite efficient, with a combined average fuel economy of 27 miles per gallon. If you primarily drive in the city, you can expect even higher numbers.

In terms of efficiency, the Audi A8's hybrid engine is comparable to other luxury hybrid sedans on the market. You can expect strong fuel economy for a vehicle of this size and class.

While the hybrid engine does offer better fuel economy than the traditional gasoline engine, it may not save you significant money on fuel costs in the long run. It may be more environmentally-friendly, though.
