Subaru's Symmetrical Awd Is More Than Just Branding – Here's How It Works

It's challenging to image an Outback, Forester, aliases Crosstrek without instantly conjuring images of these vehicles handling rugged terrain aliases plowing done snowfall pinch ease. The logic is that Japanese automaker Subaru has made an effort to marketplace its models pinch all-wheel thrust (AWD). In fact, we sewage a clasp of a 2025 Subaru Crosstrek pinch Symmetrical AWD and X-Mode, uncovering it a awesome fund action for those who admit functionality complete flashy extras.

While it tin beryllium difficult to sift done each nan trading motto thrown astir by various companies eager to scoop up your money, Subaru's AWD strategy is worthy of attention. The automaker really has respective AWD configurations, but nan astir communal will beryllium nan Active Torque Split (ATS) strategy offered pinch its models that person a CVT (continuously adaptable transmission). This peculiar configuration doesn't usage a halfway differential, but alternatively leans connected a multi-plate halfway clutch battalion to administer torque successful a 60/40 ratio beforehand to back.

Subaru's AWD ATS type is continually adjusting torque via braking unit to prime wheels, offering a full-time AWD setup. By monitoring information from various sensors measuring each wheel's traction level, Subaru's Symmetrical AWD useful to support optimal grip, nary matter what type of aboveground you're navigating.

The "symmetrical" explanation refers to Subaru's design, which eliminates nan request for redirecting powerfulness many times owed to nan observant positioning of nan vehicle's components. This symmetrical, low-mounted layout besides helps administer weight evenly and keeps nan halfway of gravity lower, improving handling. However, nan problem pinch having to redirect powerfulness to nan axle is that it results successful power nonaccomplishment and reduced response. This is an rumor pinch immoderate different AWD systems, arsenic nan location of nan motor and transmission don't statement up for optimal powerfulness delivery.

In addition, galore AWD systems are advertised arsenic "part-time," meaning they are only selectively engaged. This results successful a conveyance operating arsenic a two-wheel drive, unless nan strategy senses much traction is needed. The rumor pinch part-time AWD is that location tin beryllium a hold earlier it enables powerfulness to nan rear wheels, for example. So, essentially, your conveyance is already losing grip connected nan roadworthy earlier nan strategy automatically kicks in. 

Conversely, Subaru's AWD is ever progressive and making adjustments. This is peculiarly useful erstwhile walking during inclement weather, but tin besides beryllium highly useful successful different scenarios, arsenic evidenced by the champion Subaru models for off-roading. Basically, nan full-time AWD takes a much preventive attack to traction nonaccomplishment versus a part-time strategy that only responds aft nan fact.

The method Subaru uses to power powerfulness to nan wheels of its vehicles is called brake-based torque vectoring. Instead of sending much powerfulness to a peculiar wheel, nan strategy utilizes nan brakes connected nan other broadside to set powerfulness delivery. For instance, while cornering, a measured magnitude of braking unit connected nan wrong instrumentality focuses torque to nan extracurricular wheel, improving stability. While this is simply a cost-effective system, it isn't arsenic blase arsenic immoderate different options that usage mechanical torque vectoring, which typically offers enhanced capacity and consistency complete nan brake-based variety.

In addition, Subaru's attack whitethorn besides induce greater deterioration connected nan braking system, since it's continually utilized erstwhile adjusting torque transportation for traction, peculiarly successful challenging scenarios. This is further analyzable by nan truth you could spot brake pads deterioration down unevenly crossed nan 4 wheels, making attraction a spot much of a guessing game.

Lastly, while location are disadvantages to part-time AWD, a large positive comes successful nan shape of amended substance economy. If you're driving mostly successful two-wheel mode, nan motor doesn't person to pain much substance moving each 4 wheels. While Subaru claims nan quality successful ratio will beryllium minimal for regular driving, it does admit its full-time AWD tin usage much gas, particularly successful much demanding instances. Despite this, nan automaker has managed to connection new Subaru models that person nan champion MPG successful its lineup, pinch bully figures considering nan full-time AWD systems.
