What is the difference between rear-wheel drive and full-time four-wheel drive?

[TeaganLynn]

There are several differences between rear-wheel drive and full-time four-wheel drive: 1. Different functions: Full-time four-wheel drive means that the vehicle is independently driven by all four wheels at all times. Rear-wheel drive means that the rear wheels of the car have power. 2. Different principles: Full-time four-wheel drive distributes driving force to all four tires through a flexibly connected central differential and independent front and rear axle differentials. Rear-wheel drive uses computers and various continuously improved sensors to constantly judge the dynamic adhesion of the tires to the ground and the driver's intentions, actively controlling the differential state of the car's differential to balance the driving force of each wheel and optimize the car's performance.
