What are the advantages of the Audi A8's lightweight construction?

I've heard that the Audi A8 is much lighter than other luxury cars in its class, but how does this actually benefit the car? Does it impact performance, fuel efficiency, or something else?

The lightweight construction of the Audi A8 has several practical benefits for both performance and efficiency. By using a mix of aluminum and steel, the car is able to achieve a lower weight without sacrificing strength and stability.

The reduced weight of the Audi A8 has a significant impact on the car's handling and agility. It allows for more responsive steering and better overall control, making it a pleasure to drive on both highways and winding roads.

Not only does the lightweight construction of the Audi A8 improve its performance and handling, but it also has a positive effect on fuel efficiency. With less weight to move, the car requires less energy and therefore uses less fuel.
