"Manual transmissions are still more efficient than belt-driven
continuously-variable transmissions"
quoted from some website....
cvt dun use gears, they use belts and pulleys to simultate arbitray
gear ratios, therefore there are infinite combination for gear
ratios.
the reason why u feel that cvt is lacking in pick-up is due to the
smoothness of the transmission.... because most drivers expect the
sudden jerks and will reject a perfectly smooth transmission as
lacking in apparent power.....
fuel economy also depends on driving habits..
a manual tachometer flactuates btw 2-4k rpm, whereas for a cvt user
who finds his car lacking in power will floor the pedal, thus the
tachometer will stay constantly at the same high rpm until he eases
off the accelerator...
