How does AWD work?
Generally, AWD systems work with no input from the driver but there are some vehicles that allow a certain degree of control over how much power goes into each wheel. The power distribution is indicated in percentage, so if a system is “70/30”, it means a maximum of 30 per cent of engine power goes to the rear wheels and remaining to front. Some systems go even further to distribute power to each wheel.
Why do people use all wheel drive?
The fact that you do not need to provide any input or instruction for the AWD system to work seems to be one of the main reason most people are into all-wheel-drive vehicles. The system is constantly active, thanks to its computer-controlled system and because of that, the system provides the necessary power to each wheel whenever lack of traction is detected.

What is AWD in Subaru?
Most full-time AWD systems split the torque evenly between the front and rear axles with the use of a center differential, though there are full-time systems that vary the amount of power sent to the front or rear wheels depending on available traction. Other full-time AWD systems offer a fixed torque split, usually with a rear bias to better mimic the behavior of a rear-drive car. Subaru uses this system in its vehicles equipped with manual transmissions, including the Impreza sedan. But manufacturers are moving away from this system to a more sophisticated type of full-time AWD that incorporates automatic engagement capability.

What is the difference between all wheel drive and four wheel drive?
All-wheel drive is different from four-wheel drive. By our definition, four-wheel-drive vehicles use systems that can't vary the individual axle speeds, meaning you cannot drive them on dry streets and roads. Do so and the axles will bind—remember, your vehicle's inside wheels turn slower than the outside wheels when you go around a corner—and the car will hop awkwardly around tight turns. All four-wheel-drive systems are intended for part-time use only. They are designed for driving off-road or when the roads are extremely slippery. At all other times, these vehicles must be driven in tw0-wheel drive.
