How does the predictive efficiency assistant in the Audi A5 work?

I've heard about the predictive efficiency assistant in the Audi A5. Can someone explain how it works and if it actually helps with fuel efficiency?

The predictive efficiency assistant in the Audi A5 uses real-time traffic data to optimize the car's route and suggest fuel-efficient driving strategies. In my experience, it has definitely helped improve my fuel efficiency and save me money on gas.

The predictive efficiency assistant works by analyzing traffic data and adjusting the car's speed and gear changes to improve fuel efficiency. I've found it to be pretty accurate and helpful, especially during rush hour traffic.

I've noticed that the predictive efficiency assistant tends to favor longer, alternative routes to save on gas consumption. While this may work for some, it may not be the most practical or time-efficient option for others.
