What is the difference between quattro and 4Motion in Audi vehicles?

I've noticed that Audi uses the term 'quattro' for their all-wheel drive system, while Volkswagen uses '4Motion'. Are they essentially the same thing or are there notable differences?

Both quattro and 4Motion are all-wheel drive systems, but there are some differences in the technology used. Quattro uses a center differential to distribute power to all four wheels, while 4Motion uses a Haldex coupling system. This means that Quattro is better suited for performance and off-road driving, while 4Motion is more efficient for everyday use.
