Included on all continuously variable transmission (CVT) models like the Forester, Legacy and Outback, this option splits torque in a 60/40 ratio between the front and rear wheels.
How does AWD torque split work?
How it works: The Mazda Active Torque Split All-Wheel Drive system’s resting state sends 100 percent of torque to the front wheels. However, depending on the vehicle’s grip needs, an electromagnetic center differential can divert power to the rear wheel for up to a 50/50 torque split between the front and rear axles.
Does AWD have more torque?
Full-Time AWD This occurs whether the road is slippery or dry. 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.
What is a torque split?
A split torque transmission is a form of automatic motor vehicle transmission which is able to send power to two separate places at once, and even control how much power is sent to each output source. Such transmissions were first invented for use in helicopters, to control both main and tail rotors at once.
Why is Subaru AWD different?
Compared to rival car companies, Subaru’s famed full-time Symmetrical all-wheel-drive system is a little different. Other AWD systems wait for slippage to happen before sending power to certain wheels (often referred to as “slip and grip systems”), but Subaru’s system sends power to all four wheels all the time.

What are the problems with all wheel drive?
AWD and 4WD drive systems can add hundreds of pounds to a car’s curb weight, and that extra bulk can have a big impact on fuel economy. That’s because an engine has to work harder to move a heavier car, which means more fuel is used to move an AWD car the same distance as one with 2WD.
What is better for snow AWD or 4WD?
Is All-Wheel Drive or Four-Wheel Drive Better For Snow? All-wheel-drive systems deliver power to all four wheels at the same time, or they automatically engage torque to all four wheels when needed. That’s why all-wheel drive is best for driving on snowy and icy roads.
Is AWD just as good as 4WD?
Both AWD and 4WD will provide better traction than two-wheel drive vehicles in most everyday driving scenarios in winter weather. Large trucks and SUVs are great for towing and hauling heavy loads and usually come with 4WD over AWD. That means buyers that need to tow heavy loads should consider 4WD.
How does torque splitting work?
When we say the torque split is 50/50 “under normal conditions”, this means that when all wheels have the same adhesion (all wheels are on a dry tarmac), the moment of force that is applied to the front wheels and the rear wheels is equal. This depends on which wheels are favored and receive more torque.
What is the torque split for symmetrical AWD?
The true torque split is always variable depending on actually conditions of the axles – reaction forces of their whells and can change from 0:100 to 100:0 (or more under special conditions yet) “Symmetrical AWD” is a description of the mechanical layout of the system, not the power distribution.
What is the torque split on a Subaru?
This Subarus’ “default” torque split is 50/50, but torque can be transferred in the range from 100/0 to 0/100 front to rear, depending on which axle loses traction. Now let’s take a vehicle with automatic all wheel drive systems as an example (assume the vehicle is front wheel drive under normal conditions).
What is the torque split ratio at full lock?
At full lock, torque split becomes 50/50. Now, if front wheels lose traction completely (ice, rollers, or raised in the air), 0% torque goes to the front wheels, 100% of torque goes to the rear wheels, but the ratio stays 50/50. Understand the two things: torque split ratio can vary from 100/0 to 50/50.
How does torque split work on a transfer clutch?
When front wheels slip, the transfer clutch attaches the rear axle. At full lock, torque split becomes 50/50. Now, if front wheels lose traction completely (ice, rollers, or raised in the air), 0% torque goes to the front wheels, 100% of torque goes to the rear wheels, but the ratio stays 50/50.
