What is the difference between Quattro and Quattro Ultra on the Audi A5?

I'm considering purchasing an Audi A5 and I'm having difficulty understanding the difference between the Quattro and Quattro Ultra systems. Can someone explain the technical differences and which one is better for daily driving?

Quattro is Audi's all-wheel drive system that uses mechanical differentials to distribute power between the front and rear axles. Quattro Ultra is a more advanced version that uses a predictive algorithm to determine when power needs to be sent to each wheel, resulting in improved efficiency and traction.

In general, the Quattro system is better for daily driving as it provides better stability and handling. Quattro Ultra is more suited for performance-oriented driving as it can quickly adjust power distribution for better acceleration and cornering. Overall, it comes down to personal preference and driving style.
