I doubt it's changed under real driving conditions, with hills, valleys and overtaking happening frequently, where all types of automatic transmissions perform poorly (they can't possibly anticipate an oncoming hill or overtaking, whereas the driver manually shifts to the correct gear beforehand).
- masklinn 4y agoEvery automatic car I’ve driven would e.g. quickly downshift when pressing down the accelerator, and while this can be laggy with older AMTs I’d assume it’s not an issue on modern gearboxes, at least the not-super-cheapo ones. But probably more relevant, all automatics I’ve driven have “manual” shifters (paddles or +/- selector on the gear lever) which let you override the gearbox’s decisions, to an extent. So nothing precludes anticipating your gearing, even on an automatic.
- kllrnohj 4y agoWhat you're talking about makes a manual have fewer torque brownouts for lack of a better term, but they'd cost efficiency not gain it. Being in a lower gear before you need it is worse for mpg than being in it slightly "too late"
