But you did say 1:1 (I guess you were saying that as an exaggeration type statement) and figured it was a general statement about EV motors which is why I used the Tesla stats I knew and that BYD use reduction gears. All good.
It's weird, I know what you're saying about torque multiplication with gears but electric motors seem to be doing things that you wouldn't expect (whether driven by a generator or batteries or both).
As with the F150 video, it's quite remarkable how capable they are without the need for a low range.
Heck, haulage trains have been using diesel electric for the torque advantages for years now.
And my point on them was to the comment about driving a PHEV (series like the Ranger) in pure EV mode (by someone else) would be average vs the Generator type setup with electric motors for propulsion.
