I agree with everyone.

Here's my Lexus 3rd member mocked up in the engine bay of a VW Beetle.

It weighs 98lb and has 68hp (according to Wikipedia the gas 1.0l engine is also 68hp). I understand that the similar unit in the new Toyota RAV4 has 115hp, with twin motors and an electric differential. That would be the one to have.

The weight savings over the gas engine go to batteries with newer alchemy.

The problem with running an electric through a transmission is that the shock load applying full torque is measured in milliseconds instead of microseconds. Shredded clutches, & blown automatics as far as the eye can see. The single-speed drivetrain has 100% torque at zero RPM, OTOH it need double the horsepower rating of a gas engine and big fat wires so they don't melt.

Get the RAV4 unit, or maybe the less evolved Leaf (IDK about them).

Edit: Are you watching back episodes of EVTV? They have a store full of useful widgets, and years of explaining the ins 'n outs.
