    The first question, is their any electric motor (ac/dc) that has 180 horsepower and can fit comfortabley in a car. Second question, (if no for the first question disregard this one) how much power would be needed to power it, amps and voltage.

    Note that one horsepower = 745.699872 Watts (according to Google Calculator, anyway.) This means that if you need 180 HP, you are looking at a 135 kW output electric motor, to give you an idea of what you need :)

    The Tesla one would be 288 hp, which is 215 kw. That means you need more power than that to actually spin the motor, if I'm not mistaken. According to 375V, 900A, 3 phase AC, that's... 550kW? That seems high...
