Innocent Bystander
The overdrive concept is simple enough, but was probably of greater interest in days gone by.
In my view, the more important descriptor today is the relationship between the engine rpm and the road speed. And the coupling between the engine's torque and power curves to the thrust and power road load curves for the trip.
The more gears you have, the better shot you have at getting the coupling you want.
Brake specific fuel consumption, engine torque, and volumetric efficiency are all pretty closely tied together. Modern cars will look for the sweet spot where BSFC is near its lowest level. More speeds in the transmission means that you will have a better shot at staying in the sweet spot for more road load conditions.
I'm not going to get stuck in this quagmire too though (the ethanol quagmire was sufficienty sobering - pun intended - to teach an old guy .... me).
Suffice it to say that, for those who do not want 6 speeds, it should be very easy for you to keep your Gen III, or to find a deal on a Gen III as new people migrate to the Gen IV. The idea that this is not legitimately Gen IV in the hearts and minds of anyone who does not own a Gen III is ludicrous.
