I've been watching a lot of reviews and comparisons between the Nissan cube/Scion xB/Kia Soul etc etc and one thing that I've noticed is that a lot of reviewers don't seem to fully understand how a CVT works. That made me realize, I'm not really even sure how it works. From what I've gathered/assumed was that a CVT had one gear that was like a rubber band. The more you pressed the gas pedal, the more the "rubberband" would stretch and if you kept it at a certain speed, the band would ease itself and the engine would return to a lower RPM range even at highway speeds.
Some reviews say it shifts or feels like it shifts though. I can't say I've ever experienced that in my cube but I once had a Lancer GTS with a CVT and that had paddle shifters. I never used them, assuming they were pointless and maybe hooked up to something in the gauge cluster that would change a number on the display to make you think you were shifting?
Found a HowStuffWorks video that might help explain it:

i don't think its like a rubber band. More like a belt that is on a cone shaped, rotor? And it travels along the varying width of the rotor effectively changing rpm? I think that's right

There's a poor, poor gnome that does all the work.

It is definitely witch craft, and I love it. Honda has done a real good job getting rid of the rubber band feeling in the accord.

The CVT is easily understandable. Two pulleys that can vary their geometry, mated by a belt or chain. Small input pulley - big output pulley, low speed. As you accelerate, the input pulley becomes larger while the output pulley becomes smaller, thus decreasing the ratio.
Regular automatics, now that is witchcraft.
HFV has no HFV. But somehow has 2 motorcycles
