The term “all-terrain vehicle” is used to describe a number of small open motorised buggies and tricycles designed for off-road use. The 4-wheeled versions are most commonly called “quads,” “four-wheelers” or “ATVs” in the United States and Canada, and “quad bikes” or “quad cycles” in other English-speaking countries. Models with 3 wheels are typically known [...]

A Limited Slip Differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In a car or automobile, such limited slip differentials are sometimes used in place [...]

When a part-time four wheel drive system is enabled, the transfer case connects both the front and rear drive shafts with the transmission. These drive shafts are connected to differentials which distribute torque to the wheels via the axle. The sum of the output angular velocity of the two output shafts (connected to the wheels) [...]

Trials are probably the safest form of motorsport. All progress is made at low speed, and the emphasis is on skill rather than finishing first. However, trialling can be highly competitive. Trials take many forms, but the most common in the UK is the club trial. An area of land (often farmland or woodland – [...]

In an automobile and other wheeled vehicles, a differential is a device for supplying equal torque to the driving wheels, even as they rotate at different speeds.
In some vehicles such as karts, torque is simply applied evenly to all driving wheels using a simple driveshaft. This works well enough when travelling in a straight line, [...]
