Detailed introduction of Subaru's four-wheel drive system: 1. Full-time four-wheel drive structure: Subaru has added a bevel gear-type central differential to the transfer case, with a rigid gear connection. The electronically controlled multi-plate differential inside is only responsible for adjusting the torque distribution between the front and rear axles and cannot separate them. Therefore, the front and rear axles always receive power. Under normal conditions, the power distribution between the front and rear wheels is 70:30, making it a true full-time four-wheel drive structure. 2. Active Torque Distribution Full-time Four-Wheel Drive System: The Active Torque Distribution Full-time Four-Wheel Drive System transmits power directly from the transmission to the central differential in the transfer case, which then distributes it to the front and rear axles via a multi-plate clutch. The electronically controlled multi-plate differential receives commands from the computer and adjusts torque distribution in real-time based on road conditions, offering better reliability and practicality.
I've always driven Subaru vehicles, and they give me great confidence in rain or snow because of their Symmetrical All-Wheel Drive system, which means it constantly distributes power to all four wheels, unlike some cars that only engage four-wheel drive when needed. The engine is horizontally opposed, giving it a low center of gravity, making the ride stable and agile—no worries about slipping during turns. The system automatically distributes torque via sensors, such as sending more power to the rear or front wheels on slippery roads to ensure smooth driving. It performs well on highways or mountain roads and even includes X-Mode to enhance off-road capability, with simple operation and no need for manual switching. I recommend it to family and friends because it’s incredibly convenient for daily commutes, especially in northern mountainous areas during winter—my car has never left me stranded.
