It's way too overpowered for most ICE conversion; so an even smaller and lighter one would be fine. Now where's the batteries... Edit:"After 20 seconds, the figures drop to 134 hp and 184 lb-ft of torque.". That's more like it.

Your main hurdle is the driveline surviving the initial torque shock, so even with that 20sec power drop you still have the initial torque from a full battery as a risk. Not at all unsolvable, you just want to consider it before you break your axles!

  At this size, you don't need axles, just mount them straight to the hubs and pay a little penalty in unsprung weight. Or use stubby half-shafts.

  This is already a solved problem, as the accelerator peddle in an electric vehicle isn't a simple on / off switch, it's connected to a computer that talks to an electronic speed controller, thereby providing drive-train safe power application. The same sorts of governing functions are computer managed in an ICE powered vehicle too.

    Of course, this is in response to an engine swap, just talking out that these are all decisions to be made and thought about. People regularly drop in bigger ICE motors and blow their drivelines up. There is absolutely the option of plonking in a big torquey electric motor and sending all you've got through it, without upgrading axles or using the right settings/setup in your motor controller.

  This isn't a theoretical problem, even some ICEs with a lot of torque have warnings against flooring them from standstill to avoid axle/drivetrain damage.

    Oh I didn't mean solveable in the theoretical sense, I meant it is very much a practically solveable problem. Buy bigger axles, use a nuanced motor controller etc. It's a problem you have to solve for ICE swaps/tunes too. Just discussing that it's something you will likely want to consider if you're swapping from something low torque.

I wonder how a 100hp variant would look.
