    "If we can make the inverter just half a percent more efficient, that’s half a percent less battery pack that we have to put in the car or half a percent more range that the customer gets..."

    If true, the small size of the basic battery is beginning to make sense now; a bigger battery could easily push over 300 miles.

    Can somebody smarter than me fill me in as to why you would not have a DC motor for one of the motors in a dual motor?

    That way you can have a smaller, cheaper inverter and not use an inveter at all under low power demand conditions.....most conditions.

    I think for one Tesla wants to keep rare Earth metals used to a minimum. So you don't want to have large permanent magnets in a DC motor.

    It, also, might make it more difficult to synchronize the two motors, not to mention just making things more complicated.

    And finally the company is named Tesla which is a reference to the AC design used.

    Great news. The definition of ludicrous is "so foolish, unreasonable, or out of place as to be amusing; ridiculous" IMO since the M3 is going to have ludicrous mode its 0-60 should be less than 4 seconds..... anything higher than that will not be considered ludicrous in my book

    DC motors have brushes...yuck. Also, they have lower RPM so you would need a transmission with gears. AC is the way to go.

    Each type of electric motor has different characteristics (efficiency, cost, power density, control, etc). There are lots of different types of electric motors, and each make sense in different situations and applications. Tesla thinks the AC induction motor they use makes the most sense for their cars. It is efficient, allows very precise and accurate control, contains no rare earth permanent magnets, maintenance free, etc.

    300kW = ~402hp. Pretty close to my P85 (advertised as 416hp). Does 0-60 in 3.9-4.2 secs depending if I can get traction. Smaller, lighter Model 3 with same/similar power sounds wonderful.

    I agree. I'm looking for 0-16 to be sub 3seconds.

    Was hoping for 1 hp for every 9lbs or better.

    Someone more familiar correct me if I am wrong, but aren't these specs just for the rear motor?

    the HP/weight ratio might very well get to your 9lbs/lb-ft in AWD.

    I'd love for this to be a standard SLA, but I don't think the ModX achieves this.
