What does the term 'four-wheel drive' (4WD) imply?

The term 'four-wheel drive' (4WD) indicates that power is delivered to all four wheels of the vehicle simultaneously. This configuration enhances traction and control, especially in off-road conditions or slippery surfaces where extra grip is essential. By engaging all four wheels, 4WD systems help distribute engine power more evenly across all tires, allowing for improved performance in challenging driving situations.

While some vehicles allow for a two-wheel drive mode, the definition of 4WD specifically emphasizes the capability to drive all four wheels at the same time. Additionally, 4WD vehicles can be designed for both off-road and on-road use, so the notion that they are limited to highway use only is not accurate. Such versatility in vehicle performance is what makes 4WD an appealing choice for drivers who require enhanced off-road capabilities and better control under various conditions.
