What is the phenomenon of CVT slipping?

[AubreyDella]

CVT slipping manifests as: when the car suddenly accelerates, the engine speed increases abruptly, but there is a noticeable lack of power during acceleration. CVT transmissions are more commonly found in Japanese car models and are often referred to as continuously variable transmissions. Unlike other types of transmissions, CVTs do not produce gear-shift jerks during acceleration, offering a smoother transition that drivers hardly notice inside the car. CVT transmissions operate on a linear shifting mode. Additionally, CVT transmissions boast better fuel economy and come with an ECO mode, effectively reducing vehicle emissions. Instead of using gear meshing, CVT transmissions transfer engine power through a steel belt. If the car accelerates too rapidly or is overloaded, this belt can slip, and in severe cases, it may even break, posing potential hazards. Despite the slipping phenomenon under rapid acceleration, CVT transmissions still provide a relatively smooth driving experience.
