No idea. I equated motor to motor. I assumed that when the price was stated for the electric motor it was for the motor alone, it did not specify motor, transmission unit, controller or management systems.

If you want to compare setups that contain engine and transmission it’s still cheaper on the ICE side. An engine and transmission kit, plus engine controller, can be had for around $15k starting price.

But again, we have to note that only one engine and transmission are required in an ICE car, whereas tesla may require up to four motors. I am also picking modest V8 engines and associated transmissions. You could also pick a 4 cyl Honda engine and transmission for a little over half the cost of the V8 package. A new Honda 1.5l 4 cyl can be had for $2500. Also, again, I am pointing out retail costs. OEM costs will be significantly cheaper.

So yeah…electric motors, installed with or without any transmission parts, are more costly.

Edit: prices for tesla motors did not state it included drive unit, but I am suspicious of the source. I would conservatively place a new OEM motor at 10k retail, single unit, base model.
