What are the differences between Audi's popular Quattro and ultra Quattro systems?

I am considering purchasing an Audi and I am curious about the different options for their all-wheel-drive systems, specifically the Quattro and ultra Quattro. What are the main differences between these two systems and how do they impact the performance of the car?

Both the Quattro and ultra Quattro systems provide all-wheel-drive capabilities in Audi vehicles. However, the Quattro system is a traditional mechanical system, while the ultra Quattro is a more advanced electronic system. The Quattro system distributes power equally to all four wheels, while the ultra Quattro can vary power distribution based on driving conditions for better control and efficiency.

The main difference between Audi's Quattro and ultra Quattro systems is their technology and implementation. The Quattro system uses a center differential to send power to all four wheels, while the ultra Quattro relies on a combination of sensors and electronic control to adjust power distribution. This can result in significant improvements in handling and traction on uneven or slippery roads.
