What does fwd mean

The front wheels do not receive any power and are free to manoeuvre the vehicle. The disadvantage of a RWD vehicle are that they do not perform well in poor weather conditions such as rain or snow because they are more prone to loss of traction on slick roads.

The biggest advantage of a 4WD vehicle is that it provides the versatility and power to take on any terrain or weather condition. All-wheel drive: A drivetrain that employs a front, rear and center differential to provide power to all four wheels of a vehicle. As the name implies, all-wheel-drive systems power both the front and rear wheels all the time. It is especially helpful in slushy road conditions and when driving over moderate off-road terrain.

The AWD system can help you both get going and keep moving through mud and snow. Typically, AWD systems will deliver power specifically to one of the two sets of wheels, front or rear, meaning that when slippage is detected at one axle, power is diverted to the other axle, in hopes of finding more traction there.

AWD systems are best for quickly changing weather conditions like driving on a road or highway with intermittent snow and ice. While four-wheel drive 4WD and AWD are titles that are often used interchangeably in marketing literature, there is a difference. Generally, 4WD is best suited for severe off-road driving situations with low-traction surfaces. Nonetheless, it is also a great vehicle system for snowy driving conditions because they offer more traction than standard FWD.

Modern 4WD systems are either full-time, meaning they are always engaged; automatic, where the vehicle will automatically engage and switch between two- and four-wheel-drive mode according to driving conditions; or part-time, which requires the driver to manually put the vehicle in four-wheel drive.
