What is FWD, RWD ,4WD and AWD?

FWD - Front Wheel Drive

- While driving, engine's power is routed to the front wheels.

- Most of the vehicles are designed with additional component to send power to rear wheels when need arises.

- Manufacturing is cheaper.

- Since engine's power is more at front,it has a better pulling capacity while climbing hills.

- Most passenger vehicles use FWD.

RWD - Rear Wheel Drive

- While driving engine's power is routed to the back wheels.

- Commonly found in pickup trucks,sports car,luxury sedans and heavy duty vehicles.

- pulling capacity is more with heavy load.

- But on a slippery road,it doesn't have a better pulling capacity(Traction).

AWD - All Wheel Drive

- Feeds variable amount of torque to each axle and the driver doesn't control this.

- Great for on-road usage as it send power to the wheels that need the most.

4WD - Four Wheel Drive

- Feeds fixed amount of power to each axle and can be switched on and off by driver.

- Great for off-road and other low traction scenarios like climbing over boulders,crossing deep water.
