What is the difference between Quattro and Quattro with Ultra all-wheel drive system in Audi models?

I have been looking at various Audi models and have noticed that some come with Quattro all-wheel drive and some with Quattro with Ultra all-wheel drive. What are the differences between these two systems and which one should I choose for my Audi?

The main difference between Quattro and Quattro with Ultra all-wheel drive systems is that the Quattro with Ultra system is more lightweight and efficient, making it ideal for fuel economy. However, the standard Quattro system offers better performance and traction in more extreme weather conditions.

It really depends on your driving needs and preferences. If you live in an area with harsh winters and need maximum traction, go for the Quattro system. But if fuel efficiency is a priority and you don't regularly face extreme road conditions, the Quattro with Ultra system is a great choice.

In terms of price, the Quattro with Ultra system is usually less expensive than the standard Quattro system. But keep in mind that the Quattro system may offer better resale value in the long run.
