    I’m sure there’s concern there, but I would like to see how that is offset by the elimination of various extra systems a EV doesn’t need like the transmission, drive line, gear boxes, diffs, drive shafts, axles, and the various fluids needed for maintenance and lubricantion of these various systems.

    Then there is the mining for the various computer controlled components for these systems but that’s probably a wash.

      I don’t know how the numbers work out in a conversion like this, but in new cars EVs take about 1.5 to 2 times the emissions of ICE cars to build including battery. That being said, 91% of a ICE’s emissions are from the gas, not producing the car.

      Wtf. You obviously haven’t looked into EVs. There’s still all those things, a planetary gear set because you need Regen braking and you need wheel speed at X rpm and need to keep electric engine below… 12000? Rpm, likely lower.

      You don’t need fluid clutch, you can reduce brakes with Regen braking, but still need emergency braking. There are some designs with two motors for each wheel, but it complicated Regen energy storage.
