The Aspects of All-Wheel Drive and Four-Wheel Drive

There are still many people who think that all-wheel-drive and four-wheel-drive are one and the same. While it is absolutely true that both terms denote that power is given to all the wheels of a vehicle to give more traction, it is also true that they each serve a different purpose.

Four-wheel drive systems operate by lowering the gear ratio and providing a split differential. The configuration is found in pickup trucks and SUVs of a larger nature that are used in off-road activities. Four-wheel drive is mainly used for off-road and rugged terrain activities.

All-wheel drive is meant for vehicles that run on paved roads and that can deliver a smoother passenger riding experience. Crossover vehicles, sedans, and high-performance cars are the usual recipients of the all-wheel drive setup. A steady source of power is sent to each wheel, with some variables to compensate for differing road conditions. All-wheel drive does very well in terrible weather conditions such as heavy rain, snow and ice.
