What is VTD AWD?
Variable Torque Distribution (VTD) For this AWD system, Subaru installs a planetary gear-set as the center differential, and uses a multi-plate clutch to implement the limit slip functionality. The multi-plate clutch only acts as limit-slip protection, and it will not kick in unless wheel slip is happening.
What is Subaru VTD?
VTD = variable torque distribution. This is a marketing term used by Subaru for the AWD system used on the 5-speed automatic transmission, which is used with the 3.6 engine. It uses a planetary differential to direct power to the front and rear drive shafts.
Which Subaru has Vtd?
ONLY the 2007-2008 Forester Sports XT (with VDC) have the VTD transfer case; the XT Limited has the MPT transfer case but with a VLSD in the rear.
What is a Vtd transmission?
VTD adds a twin planetary center differential to the clutch and therefore has a static, starting torque split calculated on the planetary gear ratio, with the most common being 45:55. Active Torque Split and VTD are found in both generations of the 4 speed while the 5 speed uses only VTD.
How does Subaru Symmetrical AWD work?
Symmetrical All-Wheel Drive sends power to all wheels simultaneously for maximum traction and acceleration. In wet and slippery conditions, that power instinctively flows to the wheels with the best traction. The balanced design of Symmetrical All-Wheel Drive helps add control through uniform stability.
What year did Subaru start using CVT in outback?
2010
Either transmission helps make the 2010 Outback 2.5i models more responsive in everyday driving. Subaru has adopted a chain-type CVT, the world’s first longitudinally mounted CVT system for AWD production vehicles.
Is Subaru Outback full time AWD?
There’s a lot to love about Subaru vehicles, and their AWD system is just one of the many, many elements that make their vehicles unique….Shop Subaru AWD at Quantrell Subaru.

Is Subaru Outback AWD or 4WD?
The Subaru Outback is typically an all-wheel-drive as all Subaru car models are. All Outbacks are equipped with all-wheel drive, which Subaru says is better than ever at pushing power to each of the car’s four wheels when additional traction is needed, whether it be through snow, mud, or over the slippery ground.
What does VTD mean on a Subaru Outback?
Variable Torque Distribution (VTD) For this AWD system, Subaru installs a planetary gear-set as the center differential, and uses a multi-plate clutch to implement the limit slip functionality. Schematic illustration of the VTD AWD system.
What kind of AWD system does Subaru have?
Similar to the above VLSD AWD system, some Subaru models equipped with this Active Torque Split AWD are also equipped with a rear viscous LSD, please refer to the list at the end of this article. 3. Variable Torque Distribution (VTD)
What is the difference between VTD and CVT and AWD?
The newer CVT-equipped Subies make use of yet a third Symmetrical AWD system. The hardware is similar to the VTD system described above — both use electronically controlled multiplate clutches to control torque split — but the CVT-equipped system defaults to a front-biased 60:40 nominal torque split.
What is the torque distribution of the VTD AWD system?
Default front/rear torque distribution is 45:55; maximum adjustment is 50:50. Since there is minimal wear within the planetary gear-set, the VTD AWD system is very durable, and is capable of demanding driving conditions when engine load is constantly high, and the variance between front/rear axles’ rotation speed frequently changes.
