How Auto LSD Works in Toyota Prius Prime
Understanding Limited Slip Differential (LSD)
When diving into how Auto LSD functions in the Toyota Prius Prime, it’s crucial to grasp the concept of Limited Slip Differential (LSD). LSD is a mechanism that enables power distribution between the wheels, especially when navigating uneven or slippery terrain. Unlike an open differential that sends power to the wheel with the least resistance, LSD ensures that both wheels receive power, even if one loses traction.
In simpler terms, imagine making a turn on a slippery road. With an open differential, the wheel on the icy or wet surface might spin excessively, leading to reduced control and stability. LSD, on the other hand, redistributes power to the wheel with more traction, allowing for smoother cornering and better handling in challenging conditions.
