What is the Audi A8's top speed and how does it achieve it?

I am interested in the Audi A8's capabilities and want to know how it can achieve such high speeds. Is it primarily due to its engine, aerodynamics, or a combination of both?

The Audi A8's top speed is 155mph, which is achieved through a combination of its powerful engine and advanced aerodynamics. The engine is optimized for performance and has a high horsepower output, while the car's sleek design minimizes drag and increases speed.

In addition to its impressive engine and aerodynamics, the Audi A8 also features advanced driving technology such as an adaptive suspension system and all-wheel drive to help maintain stability and control at high speeds.
