4-wheel drive vehicles are cars, in which all four wheels to receive torque from the engine simultaneously power.
Four railcars are also referred to as 4WD or 4x4 cars.
The first four refers to the number of wheels, while the second four refers to the number of wheels to receive the power from the engine.
4W vehicles are better adapted better on low traction terrain to run as mud, snow, ice, loose gravel and slippery surfaces where 4x2 may not be the most appropriate.

A vehicle with a four-wheel-drive system can bring many benefits for those who buy them. The system itself increases the performance of the tires on a surface without having to hold slipping.
This is a big advantage especially if you like to ride in muddy areas, sand or even on slippery surfaces.
When people hear this kind of system, most of them connect the SUVs and trucks. Because of this feature can be a part of the vehicles cost a little more usual in comparison with the.
Although it so expensive, people use more people choose to buy them.



Although the term "all wheel drive" refers to a capability that can have a vehicle, it is also used to represent the entire vehicle itself.
The term 4x4, as a four by four is read, is used to indicate the total number of wheels to a vehicle, and is applied commonly equipped in vehicles with full or part-time four-wheel drive.
This term is widely used in North America.
The first all-wheel drive vehicle, Spyker 60 HP, was manufactured in 1903 by Dutch brothers Jacobus and Hendrik-Jan Spijker Amsterdam. 4X4 designs in the US came from the Twyford company of Brookville, PA 1905. The first US all-terrain vehicle was in 1911 by the all-wheel drive car company (FWD) of Wisconsin made.
Some of the first all-wheel drive cars were made different rally cars like the Ford RS200 1984-1986. In 1989 Panther Westwinds built a four-wheel drive, the Panther Solo. 2
Today, all-wheel drive systems in many sophisticated commuter vehicles and sports cars. In a 4x4 truck, when one wheel out of control, a brake is automatically applied to that wheel.
Torque will then be matched, which are power, divided between a road and a brake. It can cause brake wear, but it is effective.
