Wheel

A wheel is a device that allows heavy objects to be moved easily through rotating on an axle through its center, facilitating movement or transportation while supporting a load, or performing labor in machines. Common examples found in transport applications. A wheel, together with an axle,...

Torque

Torque, moment or moment of force , is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist....

 from several motors independent of each other. This term is coined to identify those electric vehicles whereby each wheel is driven by its own individual electric motor.

These vehicles inherently have a range of characteristics built-in that are more commonly attributed to Four-wheel drive

  Anti-lock braking system
  An anti-lock braking system is a safety system that allows the wheels on a motor vehicle to continue interacting tractively with the road surface as directed by driver steering inputs while braking, preventing the wheels from locking up and therefore avoiding skidding.An ABS generally offers...
  
  
• Anti-skid

Other features

• If one motor fails, the other motors are powerful enough to drive the vehicle to the nearest repair shop.
• Low maintenance.
• Easy replacement of motors.
• No central gear box.

The motors that are used in these vehicles are generally known as Wheel hub motor
