Subaru Symmetrical All-Wheel Drive
Seen on: Practically every Subaru vehicle
How it works: Subaru built its reputation on its Symmetrical All-Wheel Drive system, so it's no surprise that nearly every vehicle that wears the automaker's Pleiades-inspired badge is underpinned by it. Subaru's system starts with a 50/50 torque split between the front and rear axles (hence the symmetrical moniker), but can send as much as 80 percent of power to either end of the vehicle in the event of slip or divert the majority of its power to a single wheel if that's all the grip it has. Some automatic transmission-equipped models can send even more power (up to 90 percent) in either direction, but the center differential's design prevents Subaru's system from ever locking completely in front- or rear-wheel-drive modes.
