    Supposed to save "space", made for other manufacturers, but note that the biggest space user in an EV is the BATTERY, not the motor/inverter. I picture some OEM buying this motor, cramming batteries in the trunk, down the center hump, and scattered around the "space saver" motor in front. Oh, wait a minute. They're only going to offer 22 kWh, so we don't need the batteries in the front.

    Most of the OEMs will never get it. Like McDonalds trying to do burritos. They can't figure out how to roll those 3 part buns around a hamburger.

    Some other non obvious advantages:
    - much shorter cables from inverter to motor
    - EMF shielding can go around one package instead of 2 ( and no exposed cables cables carrying high frequency + AC )
    - one package to cool instead of two

    And the most obvious advantage is that you can get a much higher power charger instead of being constrained to 3.3 or 6.6 kW.

    The idea of integrating AC charger functionality in the inverter was promoted by Tom Gage, then-CEO of AC Propulsion. Most ACP drivetrains feature that (ACP T-Zero, Tesla Roadster, BMW Mini-E). See http://www.acpropulsion.com/pressreleases/11.20.2008%20BMW%20Press%20Release.pdf.
    Tesla turned away from that concept with Model S and went with separate, modular AC charger units of 10kW each. You can order one additional on board unit giving 20kW. They sit near the rear axle "torque box" and length of cable is not really a problem for 20kW. Separate cooling loops are more of a hassle.
