Benefits of Golf Alltrack 4Motion All-Wheel Drive
Volkswagen Golf Alltrack 4Motion AWD SystemBoth four- and all-wheel drive systems send engine power to all four wheels, but it’s the way that the power is sent that separates the two. The former distributes equal power to all of the wheels, whereas the latter is able to control how much power it sends to each wheel. It monitors traction of all four wheels, and if it detects any slippage, it takes power away from the traction-less wheel and ships it elsewhere. As soon as the wheel gets traction again, power is returned. The method helps to provide maximum traction.
If you’re familiar with four-wheel drive, you’ve probably heard that turning it on can really hurt your fuel efficiency. That’s because there is a transfer case that power to the other two wheels must be sent through. There is a lot of energy loss that causes you to burn more fuel. With all-wheel drive, the transfer case is designed to be more efficient, as the system is one that needs to be turned on at any given time.
To further save fuel, the Golf Alltrack operates in front-wheel drive mode until the vehicle senses that more traction is needed. If you suddenly hit a puddle of rainwater leftover from the night before, the system will flip on to get you through that puddle safely. As soon as the conditions return to normal, the all-wheel drive is shut down and the vehicle returns to front-wheel drive mode. It’s efficiency at its finest.
