No way does an electric motor cost that much.

Have you seen the amount of precision engineering that goes into building a combustion engine? That is ridiculously expensive.

    Did you check numbers before you posted or did you disagree out of hand with zero thought to it? I didn’t pull these numbers out of my ass.

    https://gbtimes.com/how-much-is-a-tesla-motor-replacement/

    $10k-$30k, I posted a midrange price. Another site had them as “cheap” as 7k, but either way if you need 2-4 of them it’s not cheap.

    That precision engineering has been establishing itself for well over a century, we get the cheaper price thanks to the economy of numbers. piston engines were driven by steam well before ICE. Yes, I am abundantly familiar with ICE engines having built several and in fact have one under assembly in my garage right now. There’s a massive difference between a boring consumer grade crate motor and any purpose-built high-end track motor as far as engineering goes even if the parts are essentially the same.

    You seem to be comparing a crate motor with the full cost of replacement of the Tesla motor. Also, is that the motor, or the whole drive unit, which from my understanding includes the differential?

    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.
