Another aspect to consider is the stock engine essentially runs at a constant speed. The CVT (transmission) performs all the torque conversion and provides the gear ratios to match speed and load.

That's why when the tachometer appears in the display in performance mode it is pretty much meaningless as a direct indication of engine speed.

can you explain further? the tachometer does not measure transmission in any way, so i'm trying to understand how you can say that the ct200h's sport mode tachometer is meaningless. it is following the rpm of the crankshaft, thus it is measuring the speed of the motor. it's not meaningless, the rpm's just rise steadily due to the cvt.
