Note that I didn't say: "现有汽车上使用的CVT，(根据你的贴子)在有

The "slippage" I'm talking about is purely from the fact that if you want to run the engine at 6000 rpm at under 5 mph, there is no magical CVT that can provide you with such a gear ratio. Then the clutch coupling the engine with the CVT must be slipping.

This is not a "极限情况", it's the "division by zero" that you cannot avoid with any transmission. And I am exactly analyzing what happens when you resolve the "division by zero" through a slipping clutch, and applying principals of physics to it. The conclusion is that you do not want to hold rpm at a constant 6000 all the way, whatever transmission you use.

Of course, you may choose to go really "ideal" and ignore certain laws of physics, but then it's your argument that is not applicable to real-world discussions, not mine.
