All-weather traction is a popular feature these days. But while some vehicles offer true four-wheel drive (4WD) systems, there are many vehicles that offer a variation of 4WD called all-wheel drive (AWD). While both offer all-weather traction, AWD is becoming more popular and is usually the system of choice among most crossover vehicles such as the Volvo XC90, the Honda CR-V, or the Toyota RAV4.

Although both systems offer added traction over 2WD drivetrains,Comparing 4WD and AWD Systems Articles 4WD and AWD are not the same, despite common confusion. The systems operate differently, and provide different levels of traction to meet the needs of different types of drivers and requirements.

A true 4WD system transfers power to all four wheels through a two-speed transfer case and drive axles. The purpose of the transfer case is to allow the vehicle to switch between Low and High range. The High range is acceptable for most bad weather or off-road conditions, while the Low range, notes Los Angeles Ford dealers, is reserved for the toughest of terrains.

Although AWD also sends power to all four wheels, it does so without a two-speed transfer case. The lack of a two-speed transfer case, explains Saturn Denver dealers, means that the system can’t handle the most severe of conditions, such as deep snow or thick mud. If yous vehicle is heading into these conditions, it’s likely you’ll need chains or other tools according to Toyota accessories retailers as the system will not deliver the level of traction needed. Although this system isn’t designed for serious off-roading, the system is certainly capable providing advanced traction on wet paved roads.

The lack of a transfer case is one of the main differences between 4WD and AWD, but the systems also different in terms of bias says Mercedes Benz Pittsburgh dealers. An AWD system tends to send more power to the front wheels in the majority of driving conditions and often automatically transfers power to a variety of wheels based on any potential loss of traction.

4WD on the other hand is often based on a rear wheel drive setup by default. Once the system is engaged by the driver will power be sent to all four wheels, rather than having a system do it automatically.

For more drivers at Used Cars Albuquerque, the AWD systems available on most crossovers will provide more than enough traction. If you desire added traction and safety for all-weather driving, AWD is certainly your best bet. The system is lighter and drains less fuel than a standard 4WD system as well. For those who want the ability to have advanced off-roading capabilities, 4WD is a heavier duty option that you may want to consider, but it might only be available on trucks and traditional SUVs as most crossovers only offer AWD systems. Before heading to the dealer with AWD or 4WD vehilces  such as Cadillac Philadelphia, decide what your needs are or if you need it at all, so that you get the right features that you’re going to use.
