What are the different driving modes available in the Audi e-Tron and how do they affect the vehicle's performance?

I am considering purchasing an Audi e-Tron and am wondering about the various driving modes. I want to know how these modes work and what impact they have on the car's performance in terms of speed, efficiency, and battery life.

The Audi e-Tron has three main driving modes: Efficiency, Comfort, and Dynamic. Each mode has its own settings for the suspension, steering, and throttle response.

The Efficiency mode is designed for maximum range and energy efficiency. It limits power and throttle response, adjusts the suspension for a smoother ride, and enables one-pedal driving for regenerative braking.
