How does the Audi A5's Sport Rear Diff perform on different terrains?

I've heard that the Audi A5's Sport Rear Differential offers better handling, but I'm wondering how it performs on different types of terrain such as wet surfaces or gravel roads.

The Audi A5's Sport Rear Differential uses advanced torque vectoring technology to distribute power between the rear wheels, providing improved grip and stability on all types of terrain. However, for optimal performance on wet surfaces or gravel roads, consider switching to the off-road mode in the Audi Drive Select system.
