Infinitely variable is a misnomer. It has a limit to the ratios available.


Marketing-speak would say it's got non-discrete ratios, hence they are
continuous, hence infinitely many ratios, hence infinitely variable.:-)

But, yeah, it's bounded.

(And the Wiki entry on the Variomatic efficiency may be a poor translation from
another language? It's oddly phrased: "Due the fact the engine runs most of the
time in its best fuel economic speed, the fuel consumption of this car was at
accepted level...)

But is variable between the lowest and highest.


Plus the two extra-special modes, outside this range! Only available for a short
period!

(These are "goes nowhere with the engine running" and "goes somewhere even with
the engine off" -- if pushed, or rolling downhill.)

I'll concede that the extra-special modes are a bit spurious. (But one is very
fuel-efficient!)
