What is the difference between Quattro and Quattro with ultra technology in the Audi A5?

I am wondering what the difference is between the Quattro and Quattro with ultra technology in the Audi A5. Do they both provide the same level of traction and handling? Is one more fuel efficient than the other? Do they have different maintenance requirements?

The main difference between Quattro and Quattro with ultra technology is the all-wheel drive system. While both provide excellent traction and handling, the Quattro with ultra technology also utilizes a predictive efficiency assistant to help improve fuel efficiency. This system can deactivate the rear axle when not needed, reducing drag and improving fuel efficiency.

Another difference between the two is the maintenance requirements. Quattro with ultra technology requires additional maintenance due to the added components for the predictive efficiency assistant. It is important to follow the recommended maintenance schedule to ensure optimal performance and longevity of your Audi A5.
