How does the Audi A7's electric power steering work?

I've heard that the Audi A7 has electric power steering, but I'm not sure how it differs from traditional hydraulic power steering. Can someone explain the mechanics behind it?

The Audi A7's electric power steering uses an electric motor to assist with steering instead of traditional hydraulic fluid. This provides more precise control and reduces energy consumption, resulting in a smoother and more efficient driving experience.

Electric power steering in the Audi A7 is controlled by a computer system, which can adjust the amount of assist based on driving conditions. This means that the steering can feel lighter or heavier depending on the speed and road conditions, providing optimal control and comfort for the driver.

Compared to traditional hydraulic power steering, the Audi A7's electric power steering is more responsive and can provide variable levels of assistance for different driving situations. Plus, it also eliminates the need for regular fluid changes and reduces maintenance costs in the long run.
