Hello folks. Just have a few hundred kilometers on the qx50. I'm concerned about engine speed. The cvt keeps the engine speed, in all gears and except when accelerating, at between 2500 and 3000. Even at highway speeds the revs stay at 2500. If I change to manual, I see the tranny is indicating "6th" even at 100 kph. I can manually force the tranny to 7th and 8th, and this shows an increase in fuel economy. But should the cvt not drop revs at highway speed by itself? Thank you all in advance.
