What is the difference between the Audi A8's standard Quattro and optional Quattro with Sport Differential?

I am trying to decide which drivetrain option to choose for my Audi A8. Can someone explain the specific differences between the standard Quattro and the optional Quattro with Sport Differential? And is it worth the additional cost?

The standard Quattro system is a reliable and capable all-wheel-drive system that distributes power evenly between the front and rear axles for improved traction. The optional Quattro with Sport Differential, on the other hand, includes additional torque vectoring technology that can actively send power to individual wheels for enhanced handling and agility.

In my experience, the Quattro with Sport Differential is worth the extra cost for those who prioritize performance. The torque vectoring system allows for better cornering and a more engaging driving experience.

If you mostly drive in normal road conditions and don't plan on pushing the car to its limits, the standard Quattro should suffice. But if you want the ultimate driving experience and are willing to pay for it, the Quattro with Sport Differential is a must-have.
