What does the 4-wheel drive system of the Vauxhall Grandland do?

I'm considering purchasing a Vauxhall Grandland, but I don't understand the purpose of the 4-wheel drive system. Can someone explain its function and whether it's necessary for my driving needs?

The 4-wheel drive system in the Vauxhall Grandland is designed to provide better traction and control in challenging driving conditions, such as slippery roads or rough terrain.

If you regularly drive in areas with harsh weather or uneven roads, I would recommend opting for the 4-wheel drive option. It can also be beneficial for towing heavy loads.

However, if you mainly drive on well-maintained roads and don't encounter extreme weather or terrain, the front-wheel drive option should suffice.
